File S/P-6, obtained from Captain Paul Clampitt, Everett, WA - Vessel name Majestic, hailing port Seattle, converted 1923 wood schooner, LOA 65' x LWL 58' x Beam 16' x Draft 13' x 33 Tons - Sea anchor: 24-ft. Diameter Para-Tech on 600' x 3/4" nylon braid rode, with 3/4" bronze ball-bearing swivel - Full trip line - Deployed in a southeasterly gale in 300 fathoms of water about 40 miles south of Yakutat Bay, Alaska, with winds of 40-50 knots and seas of 20-30 ft. - Vessel's bow yawed 20°

Washington fisherman Paul Clampitt is the owner of the 65-ft. schooner Majestic. While longlining, he routinely uses a 24-ft. diameter Para-Tech sea anchor for station keeping, allowing the crew to get a good night's sleep offshore. On the occasion of this file the same 24-ft. sea anchor was used in a southeasterly gale in the Gulf of Alaska. The para-anchor did a good job of holding the bow of the boat into the seas - bearing in mind that this is a converted 1923 wood schooner with a full keel and stern draft of 13 feet. Transcript:

The parachute sea anchor requires some skill to learn how to properly deploy. We deploy it using a "flying set," by setting the chute off the stern and allowing it to open, then turning the helm upwind with the engine in neutral. The main advantage in using the anchor is in getting a good night's sleep without having to man the helm through a gale. We have yet to use the chute in true storm conditions, because in life-threatening situations I don't want to experiment, and prefer to have a man on constant watch - so we might as well maintain steerage way by jogging up into the seas. But it is a comfort to know the chute is available for deployment in case of loss of power.

In our case the chute doesn't really help that much in stopping the boat from drifting, however, because most of our drift occurs from strong tides in our areas of operation and the vessel and chute drift at the same rate in these situations.

24-Ft. Dia. Sea Anchor

Force 8-9 Conditions

File S/P-5, obtained from Captain Dennis Crosby, Youngstown, FL. - Vessel name Ashly G, hailing port Panama City, FL, Thompson trawler, LOA 55' x LWL 50' x Beam 18' x Draft 10' x 60 Tons - Sea anchor: 24-ft. Diameter Para-Tech on 400' x 3/4" nylon three strand rode, with 3/4" galvanized swivel - Partial trip line - Deployed in low system in deep water about 150 miles south of Mobile, Alabama, with winds of 35-45 knots and seas of 15 ft. - Vessel's bow yawed 10° - Drift was estimated to be 4-5 n.m. during 24 hours at sea anchor.

Ashly G's partially torn sea anchor came back for repairs a number of years ago. Upon inspection the first thing Victor Shane noticed was that the canopy was inside out! The skipper of the boat could not recall how this came about. Most sea anchors and parachutes have a heavier, skeletal, web framework that cradles and reinforce the lighter canopy material. If the parachute is used inside out high loads may tear the canopy away from the radial basket, which is probably what had happened here.

Upon further inspection Shane also noticed heavy damage in the vent-hole area.

The vent-hole is the discharge orifice incorporated into the top of the canopy to afford stability and shock absorption. This is a very critical area where there is tremendous water pressure trying to squeeze through a small hole. The nylon cloth of the parachute is not strong enough to withstand the pressure, so the vent-hole has to be heavily reinforced with webbing - it is the strong webbing that takes up the strain, and not the lighter canopy material. And indeed, in this case it had been redundantly reinforced.

So what could have happened?

Further investigation revealed the culprit: CHAFE! The trip line has to be tied off to something. Usually that something is the webbing that reinforces the vent-hole. In daily use the trip line rubs and pulls against the webbing. Chafe does the rest. Once the reinforcing webbing has chafed through the high loads have to be born by the lighter canopy itself, usually resulting in failure of major proportions.

Shane was quick to bring the matter to the attention of Para-Tech's Don Whilldin. A master parachute rigger and veteran skydiver (more than 1000 jumps), Whilldin went to work and redesigned the critical vent-hole area.

All Para-Tech sea anchors now have a separate recovery bridle, to which the trip line may be attached independently of the critical webbing that reinforces the vent-hole.

Diameter Para-Tech on 600' x 7/8" nylon braid rode, with 5/8" galvanized swivel - Full trip line - Deployed in a whole gale in deep water about 150 miles SE of Morgan City, Louisiana, with winds of 45-60 knots and seas of 15-20 ft. - Vessel's bow yawed 10° - Drift was 8-10 n.m. during 48 hours at sea anchor.

Captain Gorman III is one of numerous commercial F/Vs that work the Gulf of Mexico out of Panama City, Florida. Many are equipped with sea anchor. Some carry 1000 feet of nylon rode on a hydraulically operated reel. Captain Gorman III routinely uses her 24-ft. diameter Para-Tech sea anchor for sea layovers and station-keeping offshore. In March 1988 her skipper, Bobby Lucas, deployed it about 150 miles south of the Louisiana coast in a gale. Transcript:

I am a longliner fisherman for tuna and swordfish, and I fish anywhere from 100 to 200 miles offshore. During the winter I am in a lot of rough weather. I used to idle into the sea or idle with the sea to keep from lying dead in the water and getting hit broadside by big waves. It is very dangerous not to have any way of anchoring. Now I always carry my 24-ft. sea anchor so that I can get my bow around into the sea and keep from lying in the trough in rough weather. I have been anchored in 50 knot winds, gusting 70, and seas of 12-20 ft. for as long as 48 hours. Without the sea anchor it would have been a very uncomfortable ride and possibly I would have had to steam in to port. Offshore, it is necessary to have a sea anchor.

File S/P-3, obtained from Captain Michael Monteforte, Kenyon, RI. - Vessel name First Light, hailing port Point Judith, RI, commercial F/V, designed by Walter Bechman, LOA 66' x LWL 62' x Beam 21' x Draft 12' x 120 Tons - Sea anchor: 32-ft. Diameter Para-Tech on 150' x 1¼" nylon three strand rode, with 3/4" stainless steel swivel - Full trip line - Deployed in a whole gale in shallow water (60 fathoms) about 150 files from Boston with winds of 55 knots and seas of 20 ft. - Vessel's bow yawed 10°.

According to the Bureau of Labor Statistics, commercial fishing ranks as one of the most hazardous occupations in the United States.

Those of us who sail offshore for pleasure can pick our season and our route, and change both if necessary. But the skipper of a commercial F/V is up against an economic imperative. "Breaking up a trip" can be an expensive proposition. He has spent hundreds of dollars in fuel, ice and provisions, and the crew has to get paid whether they catch fish or not. So what happens when the Weather Service issues an untimely bulletin? Given today's shaky economic picture, the skipper has to make a difficult decision as to whether to go ahead with the trip, or to abort and head back for port with the holds empty.

In the course of interviewing scores of offshore fishermen, Victor Shane discovered that, as a general rule, most will stay on the fishing grounds and ride out the average gale, especially if the trip is still young. The majority will steam back for port in the event that the forecast is upgraded from "gale" (34-40 knots sustained) to "storm" (48-55 knots sustained). Sometimes they get caught out there in between.

Now when a commercial F/V runs into an offshore gale it is standard procedure to "jog into it" - an expression used by commercial fishermen themselves. The engine is placed in slow forward and the F/V makes just enough way to enable the helmsman to keep the bow pointed as high into the teeth of the gale as possible. Fuel is spent in jogging into the seas; the hull may pound some; there is the wear and tear on everything and everyone. And if the vessel loses power, if she springs a bad leak, or if something major - like a pump - breaks down, she may end up needing the assistance of the Coast Guard.

This is why commercial fishermen were among the first to use parachutes at sea. With the parachute set they can shut down all engines and stay on top of the fishing grounds, anchored to the surface of the ocean in relative comfort. Transcript of Captain Monteforte's testimonial:

I used sea anchors for four years on my last boat, the Dyrsten. She was 60' long by 20' wide, made of yellow pine planks with oak ribs. Her gross weight was 38 tons. We used surplus parachutes then, but suffered with the problem of the chutes blowing out, so we always carried a spare. I thought about a chute for my new boat, First Light, but because she is at least three times heavier than Dyrsten, I didn't follow up on the idea, until last January, when I called Para-Tech, after seeing their ad in National Fisherman. I purchased a 32' diameter chute... a well-made, extremely rugged looking sea anchor.

We started using it on the very next trip. We would fish all day, and lay to the chute during the night. What we experienced at sea anchor was a very peaceful motion, as the bow of the boat tracked its way into the oncoming swells. The ride was different than if you were to jog into it. I suppose there was just less pitch, allowing for a good night's sleep. On one particular trip in March '88 we were fishing at least 150 miles offshore when, on the second or third day of the trip, the barometer started to fall rapidly. Now, ordinarily, we are left with two choices if the weather deteriorates: steam home, or lay to. Unless the forecast is really bad, we invariably lay to. At any rate, we set the chute before dark and when I got up at dawn the wind had already shifted to the northeast and was blowing 30 knots. Having noticed that the barometer was still low, I decided to remain at sea anchor a while longer. As it turned out we remained at sea anchor for another day and night. The wind increased to fifty five, sixty knots, with higher gusts.

The whole time that we were hove to the sea anchor we were comfortable and relaxed. When it was over, we were rested, in good shape, and anxious to get back to work. In my opinion, a sea anchor, used with good judgment, is an invaluable tool.

File S/P-2, obtained from Captain Marc Palombo, Sandwich, MA. - Vessel name Holly & Michael, hailing port Sandwich, commercial F/V, designed by Washburn and Doughty, LOA 65' x LWL 60' x Beam 16' x Draft 6' x 43 Tons - Sea anchor: 28-ft. Diameter C-9 military class parachute on 450' x 3/4" nylon three strand rode, with 5/8" galvanized swivel - Full trip line - Deployed in a whole gale in shallow water (45 fathoms) about 75 miles SE of Nantucket with winds of 45-55 knots and seas of 18 ft. - Vessel's bow yawed 10° - Drift was estimated to be 15 n.m. during 24 hours at sea anchor.

 

Captain Marc Palombo is president of Calico Lobster, Inc.. He has a number of commercial F/V's that work out of Sandwich, Massachusetts. These lobster boats, designed by naval architect Bruce Washburn, have proven to be extremely stable platforms at sea. Because of their hard chines they don't roll very much. Their low profile allows them to fish in high winds, and their wide open after decks can accommodate hundreds of lobster traps. Palombo called Victor Shane's company a number of years ago about C-9 parachutes for the boats. It seems that a member of his crew, Arthur Davey by name (see previous file), kept insisting that they should have one on board.

Shane explained to Captain Palombo that he had a few C-9's in stock, but that in his opinion they were not suitable for a big, 40-ton commercial F/V. He reminded Palombo that they were parachutes, designed for one man jumping out of an airplane. Captain Palombo insisted that he wanted three of them. He said Arthur Davey had told him they should be adequate.

Shane said "O.K", but went to great lengths to explain the importance of the long rode, "Remember, the long rode acts as a load buffer. THE LONGER THE RODE, THE LESS THE STRAIN ON EVERYTHING!"

Those C-9 parachutes were subsequently used by the Calico fleet in heavy weather, in conjunction with 400-500 feet of nylon rode. They didn't tear, and some were still in use years later. In 1986, for instance, the Holly & Michael used one in a November gale on the Georges Bank - 45 fathoms. Transcript:

I am writing to compliment you on the usefulness of the PARA-28 [28-ft. C-9]. As an offshore Lobster Fisherman I have deployed the parachute many times. I am completely satisfied with its operation. In one instance, we deployed the chute in a November 1986 gale, 75 miles south-east of Nantucket. The weather conditions deteriorated rapidly and we found ourselves sitting in 45 knot winds with about twelve foot seas....

"Through the toughest twenty hours of the storm we lay to the parachute.... The PARA-28 kept our bow into the seas as we drifted. We did not pound into the seas, nor did we lie beam-to. It was a soft, comfortable manner to ride out the storm." (Photo courtesy of Captain Marc Palombo, Calico Lobster, Inc.)

For about twelve hours the National Weather Service out of Boston had storm warnings up. Through the toughest twenty hours of the storm we lay to the parachute. We were as comfortable as could be expected under these conditions. The PARA-28 kept our bow into the seas as we drifted. We did not pound into the seas, nor did we lie beam-to. It was a soft, comfortable manner to ride out the storm. The parachute enabled us to stay and ride out the storm. Some of the other vessels went into port with broken trips. We stayed and were able to complete our trip. In this respect the anchor paid for itself tenfold. I must stress that there is no substitute for good common sense in some of the decisions to either go home or stay out. But if I were to decide to stay and ride out a storm, I would definitely want a parachute sea anchor out.

Commercial F/V

50' x 22 Tons

28-Ft. Dia. Parachute Sea Anchor

Force 10 Conditions

File S/P-1, obtained from Captain Arthur Davey, Yarmouth Port, MA. - Vessel name Sea Roamer, hailing port Hyannis, MA, commercial F/V, designed by Gallagher, LOA 50' x LWL 48' x Beam 16' x Draft 6' x 22 Tons - Sea anchor: 28-ft. Diameter C-9 military class parachute on 150' x 3/4" Poly-Dacron rode with 5/8" galvanized swivel - No trip line - Deployed in a storm in shallow water (60 fathoms) 75 miles east of Chatham, Massachusetts, with winds of 50 knots and seas 20-30 ft. - Vessel's bow yawed 10° - Parachute disintegrated after 20 hours (probably due to short, low-stretch rode).

This file was derived from numerous telephone conversations with Captain Arthur Davey, along with an article called The Wreck Of The Sea Roamer by William P. Coughlin of the Boston Globe (courtesy Boston Globe).

At the time, Captain Arthur Davey was a 30-year veteran of the commercial fisheries. He has been through more storms than he can remember. This one was different, however.

On the night of Tuesday 15 December 1981, Sea Roamer, a steel-hulled gillnetter out of Hyannis, was about 75 miles offshore, riding to her 28-ft. diameter parachute in 30-knot winds. The rode consisted of about 150 feet of 3/4" low-stretch Poly-Dacron. The barometer was dropping. There were warnings of two weather fronts, with an interval of 12-18 hours forecast between them. A faster moving upper altitude TROUGH was about to overtake and reinforce a surface LOW (classic "bomb" type storm development, similar to Fastnet '79.)

By 8 a.m. the next morning it was blowing 45 knots as Sea Roamer's bow, snubbed to her parachute, lifted in what now were 30 ft. combined seas. One and a half hours later it was blowing 50 knots - with 90-knot gusts recorded at Chatham Weather Station.

The 150 feet of Poly-Dacron rode was not long enough, nor did it have sufficient elasticity to absorb the dynamic loads imposed by the wind and the seas on the 22-ton commercial F/V. Those loads were being transmitted directly to the lightweight surplus parachute in the water, and it began to fail - panels began to blow out.

Sea Roamer's bow began to swing off the wind in an increasing arc. The parachute finally disintegrated and Captain Davey had to cut away its remains. Sea Roamer came beam to the seas and began rolling heavily, rails buried. The skipper fired up the engine and put her on a westerly course, the 300 horsepower Caterpillar Diesel chugging at 1200 RPM. That was when the two weather fronts came together. They fell into synch, "Right on top of us," Captain Davey said. No 12-18 hour interval. No window of escape for Sea Roamer. The forecast had been wrong.

The seas rapidly built until some of them started to curl over and break. Arthur Davey was at the helm, trying to call them. He had to steer carefully, using Searoamer's bow as a shield. When he saw one coming he would head into it by putting down the wheel and easing off on the throttle. The wave would slam against the bow, making the hull pivot on its CLR. The skipper would then apply throttle again, inching westward, rounding up north to parry off another wave, then inching westward....

Captain Davey: "Once in a while, one would break over the bow, but I wasn't concerned. I had been caught in it before. And, if worse came to worse, I figured we could go further to south'ard and go in the deep water route by Great Round Shoal Channel."

An hour later the wind was screeching at hurricane force - 75 miles per hour sustained. The sea had become white with foam and was now delivering hammer blows at Sea Roamer's steel hull.

Already the Coast Guard had its hands full. For that was the dreadful night in which the 94-ft. F/V Pioneer went down and all hands had to be rescued. Meanwhile, Marjorie and Arthur Davey Sr., the skipper's parents, had been calling Sea Roamer over the base station from their home at South Yarmouth - to no avail. Their concern mounted until finally a call was put through to the Coast Guard. Soon they were listening on Channel 16 as the Coast Guard station at Chatham put out its own calls: "Come in Sea Roamer. Come in Sea Roamer." There was no answer.

Sea Roamer, apparently out of range, continued to inch her way through streaked, white mountains of water until 3:40 in the afternoon. That was when the hands on the ship's clock stopped - a watery giant, coming from a different direction, curled and exploded right on top of her.

"It was a rogue. A rogue wave of good proportions," Captain Davey said later, "I was at the wheel. I was on watch. That's all I remember to this day. How it hit, I don't know. I can vaguely remember the chopper, then the brain scan machine at the hospital. That's about it."

The wave ripped open and devastated Sea Roamer's heavily built oak and plywood wheelhouse. It also knocked the skipper unconscious. According to Roy McKenzie, mate for two years, "Everything was blown out in the wheelhouse. The captain was on the floor... the doorway was gone. Blood was pouring out of both his ears, his forehead and mouth. His eyes were open, rolled back."

Somehow McKenzie and deckhand Jack La France managed to get the unconscious Arthur Davey into a survival suit, and then put their own suits on. Sea Roamer lay dead in the water, with three of her five watertight compartments flooded forward. "The sea had gone to just foam. It was all white. Terrifying. You could hear the wind. That shrieking noise. That roaring," said McKenzie.

They deployed the life raft and struggled with it, but had to cut it loose, unable to put the unconscious captain in. The seas were now breaking regularly and Sea Roamer was lying a-hull, rolling heavily - up to 60°. Twilight descended. A tanker passed by, but didn't see the lights that they flashed at it - it was having troubles of its own. Exhausted, the men lay down on the steel deck next to their unconscious captain. Both recall having lifelike visions of their past lives.

By dawn the next day, the Coast Guard had a helicopter and a fixed wing Albatross out of Otis Field searching for Sea Roamer. On board the boat, Captain Davey suddenly groaned, opened his eyes, and looked around. "What happened?" he asked. "Get on the radio. Call the Coast Guard. And, Jack, Jeeze, will ya close the door. It's cold in here." There was no door to speak of - it had been blown away. The radio had been damaged - and the EPIRB lost - when the rogue wave hit. But McKenzie and La France bailed and managed to reconnect the battery line to the engine. They found the starter switch in the jumble of wires and hit it. The big diesel turned, stopped, turned again, caught and started to chug.

Sea Roamer was under way again, but her captain lapsed back into unconsciousness. The men steered for the west and kept bailing with buckets. At 12:39 p.m. on Thursday Dec. 17th, Lt. Steve Hilfery and co-pilot Lt. Ted Ohr, flying an Albatross seaplane out of Otis Field, spotted the little white hull of Sea Roamer in the rough sea below and a message quickly crackled back to the air station: "Located F/V Sea Roamer. Position, 41-dash-31 North latitude, 68-dash-50 West longitude, proceeding 330 degrees at five knots. Appears disoriented. There is damage to the pilot house."

The twin engined plane banked, turned and made a low-level pass over the boat. When the men heard the aircraft roar overhead they began sobbing uncontrollably. They came out and waved their hands.

CHOPPERAt 2:55 p.m. a Coast Guard helicopter lifted the unconscious Captain Arthur Davey to safety, the seventh human life it had plucked from the ocean on that day.

The ordeal ended the next morning when the cutter Point Bonita eased into her berth at Woods Hole, having put three Coast Guard seamen on board Sea Roamer for the slow tow to Hyannis, and having taken La France and McKenzie on board the cutter for initial treatment for "harsh exposure." Roy McKenzie's wife Melody and his son, Roy Jr., were standing at the dock as lines were heaved to the Point Bonita. Jack La France stepped onto the concrete dock and made a vow never to go to sea again, a vow that he has yet to break.

But Captain Arthur Davey? Well, no sooner did he get released from the hospital than he was right back offshore, staring down another winter gale on the Georges Bank. For cryin' out loud Arthur.

How would Sea Roamer have fared at sea anchor if she had used 600 feet of elastic nylon rode instead of only 150 ft. of low-stretch Poly-Dacron? Would she have been able to ride out the storm without damage? We will never know, but Arthur Davey told Victor Shane that he was never too old to learn. He still uses parachutes at sea. But now with a long NYLON rode.

The F-27 trimaran is trailerable, fast and seaworthy. Steven Wann used a para-anchor on his in a gale seventy miles off the New Jersey coast. Transcript:

I feel that I should mention that I have made one Pacific and four Atlantic crossings. While all of my ocean crossing have been in monohulls, I have made a few ocean passages in multihulls and expect that I will be doing more multihull ocean sailing in the future. I am aware of the differences between monos and multis, especially in regards to what I call "offshore tactics." For example, I have found that lightweight trimarans like the Corsair series do not go well to windward with waves coming from windward. As Sheldon Bacon mentions in his chapter entitled "Wind Waves" in the latest edition of Coles's Heavy Weather Sailing, seas take some time to build, and the "sea state" often lags behind the "wind state." Thus skippers of multis sailing offshore have to be aware that even though the wind might remain constant in strength and direction over a period of time, the ability of some mutihulls to continue to windward can diminish if the seas build.

In the case of my DDDB form for 19 July '97, it should be noted that the waves were not commensurate in size with the wind force: they were smaller. However, I deployed the sea anchor because

1) the wind and waves were from my destination,

2) I was single-handed and tired,

3) I was in no hurry, and

4) there was sufficient traffic in the area to make me feel that maintaining way and a good lookout would be impossible.

I would like to point out that I was not in any danger, I did not need assistance. In other words, I used the sea anchor not as an emergency device, but as part of my "normal" offshore tactics. I feel this is an important point.

In the case of my DDDB form for 16 August '97, I felt I was in an unsustainable situation: I had considerable gear failure (instrumentation, bowsprit and autopilot mounting, to mention a few), the wind and seas were from my destination and building, the weather forecast was for more of the same for the next two days, and I was exhausted. Thus I felt that I was unable to continue under those situations.

I would add that there are at least three situations in which I would use a sea anchor:

1) "I don't want to continue under the current weather conditions."

2) "I can't continue, but I don't need assistance."

3) "I can't continue and will need assistance when the present weather conditions moderate."

For the second deployment I had removed the trip line and float. I saw no advantage in their use during the first deployment and was concerned that the trip line could foul the chute in some way. Regarding bridles, I felt that Corsair's eyes near the bows of the outer amas were inadequate for the load that might be placed on them, were I to use a bridle. As I see it, the only advantage of a bridle on a multihull is to stop the boat from yawing, and in my case I did not see the yawing to be a problem. The yawing, which I felt was considerable, was in no way apparent belowdecks, and in any case is something that most multihull sailors have probably become accustomed to at ground anchor.

On deployment the first time, I was surprised how easy the movement of Dancer became instantly, and how things quieted down. It was a "time out." This was repeated on the second deployment.

I was also surprised at how much stretch there was in the rode, and how difficult it was to retrieve the rode and the sea anchor. The effort was much greater than just hauling in on a ground anchor rode, for at the time there was still considerable wind and sea. Even though the F-27 only displaces 2600 pounds, considerable effort was required to winch in the rode and sea anchor, and in the time it took to do so I worked up a good sweat. I had run the rode from the port fairlead to starboard of the bow cleat and back along the deck to the port winch, just forward of the cockpit. I would recommend this lead to other F-27 owners. There was so much strain on the rode that it would stretch six inches just from the bow to the winch!

Another surprise was that the sea anchor [without float] took a position not near the surface of the water, but down maybe 30° from parallel to the surface of the water. While I didn't have any chain on the rode, the weight of the sea anchor, fitting, swivel and line were enough to sink the setup considerably, possibly because of relatively light wind conditions [at retrieval time]. On retrieval, I learned to watch the bow drop into a trough and then winch like mad!

Gary Habersetzer is one of the original group of multihull builders/sailors who learned how to use parachute sea anchors directly from John Casanova (File S/T-1). The group included Carol Donovan, owner of the 35-ft. Horstman Tri-Star Lion's Paw, Jim Staggs, owner of the 41-ft. Nottingham trimaran Whither, Jack Beadle, owner of a 32-ft. Simpson Wild "Shifter" trimaran, and Bob and Marilyn Braggins, owners of the very first flush deck Horstman Tri-Star ever built, Puffin.

Gary bought his first surplus military parachute from John Casanova in 1975, using it in a whole gale aboard his first multihull, a 31-ft. Piver AA trimaran off Cape Mendocino, California. When Gary, along with Bob Braggins, was invited to fly over and help sail a newly-built Horstman Tri-Star from Seattle to San Diego, he brought along two parachutes.

The story about him boarding the plane with two 28-ft. C-9 parachutes rolled up under each arm - causing not too little anxiety among the passengers - is well known in multihull circles. Bringing those parachutes turned out to be a wise decision, however, because the Tri-Star ended up having to use one in a gale off the mouth of the Columbia River.

In the July/August 1979 issue of Multihulls Magazine Joan Casanova wrote about the dangerous behavior of the boat prior to deployment (reproduced by permission):

The small Tri-Star rose above the monstrous waves, sliding swiftly down each face. Every few waves which passed under the boat were just a little larger than the last ones. It sent the tri skidding off at a 45° angle, nearly coming to complete broaching position in the trough. the action gave the helmsman anxious moments before the boat would respond to the helm. All aboard knew the dangers of that position. They were aware that the tri exceeded a safe speed. Below decks all gear was rolling in the aisle. It was only a matter of time before the growing seas would roll the lightweight trimaran over. Bob Braggins, skipper of Puffin, reflects in his tone of voice those anxious hours, as if reliving them.

"I'm sure we would've gone over if we hadn't put out the chute. We had difficulty putting it over the side at first. The wind got hold and wanted to open it on deck. As soon as it took hold in the water, the boat began to ride easily and we began to relax. It was my first time using a chute, and believe me, I am sold!!"

Gary has used the parachute sea anchor too many times to list all of them. On the occasion of this particular file he and his wife Karen were sailing Amenity from San Diego to Cabo San Lucas when the wind and seas suddenly came up near Magdalena Bay. Amenity was hove-to for twelve hours, after which she resumed her cruise south. There is a photograph of Gary and Karen folding the parachute on Amenity's deck in the July/August '79 issue of Multihulls. The photo was taken by Joan Casanova.

In 1976 Gary Habersetzer went into business for himself as head of Marine Repair Service in San Diego. After two decades of multihull building experience he founded Pedigree Cats in Seattle in 1995. The company now builds large multihulls. At this writing there are several large Horstman Tri-Stars in the works, including one that is 105 feet long. A 52-ft. Shuttleworth design with a high-tech Aero-Rig is nearing completion. Pedigree Cats has also received an offer to build catamarans for an Austrian concern.

The short note that Gary sent in along with the filled out DDDB form reads thus:

I think you now know why we list the chute as standard equipment on all the cats we build. We have used them and know that you should not leave the dock without one.

ENCHANTS/T-19

Trimaran, Piver

55' x 25' x 15 Tons

24-Ft. Dia. Sea Anchor

Force 11-12 Conditions

File S/T-19, obtained from Mel Pearlston, Petrolia, CA. - Vessel name Surrender, hailing port Petrolia, trimaran ketch, designed by Arthur Piver, LOA 55' x Beam 25' x Draft 4' 7" x 15 Tons - Sea anchor: 24-ft. Diameter Para-Tech on 600' x 3/4" nylon three strand tether and bridle arms of 75' each, with 5/8" stainless steel swivel - No trip-line - Deployed in a North Pacific storm in deep water about 500 miles west of Humboldt Bay (California) with winds of 70-80 knots and seas of 50 ft. - Vessel's bow yawed 10°.

Mel Pearlston was sailing Surrender back to California from Hawaii in 1992 when she ran into a September storm. A 24-ft. diameter Para-Tech sea anchor was then deployed, which kept her three bows snubbed into the seas for about three hours. The anchored trimaran was then struck by a rogue wave coming in at an angle of 30-40°. As to what happened next, the best that Pearlston and Shane could determine after long telephone conversations is as follows. Either the trimaran was picked up and carried sideways, inducing considerable slack in the system, which allowed the yacht to lie a-hull temporarily. Or the sea anchor itself was picked up and thrown - possibly fouled - by the same rogue wave, causing the line to go slack and the yacht to lie a-hull. Or a combination of both (Fig. 40).

Although mercifully rare, large breaking rogues are capable of dealing swift and unexpected death blows to small craft. One needs to try to come up with additional tricks that might improve one's odds of survival in the event of such an encounter. Perhaps one such trick would be to deploy an auxiliary - smaller - sea anchor on a much shorter line off the approach ama, if one knew which side the rogue was going to come from. Or possibly the main hull, if one did not. This sort of strategy was once used on some of Richard Newick's earlier Vals, the idea being that if a capsize couldn't start it couldn't finish. Several OSTAR Vals, among them Three Cheers, rode out storms on double sea anchors. Perhaps this auxiliary sea anchor could be a weighted, 3-5 ft. diameter cone with a wire hoop sewn into the skirt to keep the mouth permanently open, deployed on 30-50 feet of line.

Conditions being life-threatening Pearlston made a quick decision to cut away the rig and run downwind. Transcript:

Surrender left Kauai, Hawaii in early September, 1992, when hurricane Iniki was just leaving the coast of Baja and turning west across the Pacific. There were three of us aboard Surrender, a modified Piver Enchantress, stretched to 55'. Surrender had been lovingly and heavily built over a twenty year period by a master craftsman, and I had been sailing her for five years in the Eastern Pacific. After sailing north on a port tack for a week, we turned right and headed across the top of the North Pacific High for our home port of Humboldt Bay. Just about this time hurricane Iniki was devastating Kauai, destroying every boat on the island. The distress channels were full of incoming calls, spread over a thousand mile radius. We were counting our blessings for having left when we did, thinking that we were home free.

I awoke three mornings later about five hundred miles west of Cape Mendocino to the blackest and most ominous horizon I had ever seen. The forecast was for a low pressure system to produce 40 knots of wind and seas of from 15 to 20 feet, but I didn't believe a word of it. The wind built quickly from the NNE to 45 knots, at which point I made the decision to deploy our 24' Para-Tech sea anchor. The anchor was attached to 600' of new 3/4" three strand, 75' bridle arms, a 5/8" SS swivel, and was secured to the boat by massive, custom-made stainless steel bails on the bow of each ama. No trip line was used, but two 24" diameter mooring balls were used for floats, together with a man overboard pole to make visual observations and recovery easier.

 

Surrender's close encounter with a rogue wave. Likely the rogue moved or threw the parachute and/or the boat, causing the line to go slack. Note that if the tether is 600 feet long and the rogue is approaching at an angle of 45° the pendulum would have to swing through an arc of 450 feet before the boat could get a full assist from the sea anchor. In this sort of situation it might make sense to additionally deploy a small auxiliary sea anchor on a much shorter line off the approach ama (in this case the starboard ama), which was a tactic used on board some of Richard Newick's Vals in earlier days, to keep a capsize from starting. Perhaps this auxiliary sea anchor could be a heavily weighted, 3-5 ft. diameter cone with a wire hoop sewn into the skirt to keep the mouth always open. The amount of assist rendered by the big parachute, of course, will depend on the angle at which the rogue is approaching with respect to wind direction. Either way, if the parachute is not hopelessly fouled it should eventually re-exert its pull as the pendulum swings back into the wind. It may take a minute.

Either way, if the parachute is not hopelessly fouled it should eventually re-exert its pull as the pendulum swings back into the wind. It may take a minute.

By the time the sea anchor was deployed and the boat buttoned up (which included lashing the helm amidships), the wind had built to fifty knots and the seas were building quickly. Over the next three hours we rode extremely comfortably to the sea anchor while conditions continued to deteriorate. The wind increased to a sustained 70 knots, gusting over 80. The larger waves were in the fifty foot range, and the swells were 600 feet apart. While riding to the sea anchor Surrender did not yaw perceptibly. As we rose to each wave the boat would rise and begin to be carried back until the anchor rode came up tight. Then, like a huge rubber band, it would gently pull us through the top of the swell. It was truly a testament to the use of the sea anchor. To this day I remember thinking how eerie it was that we could be so comfortable in such conditions.

At the height of the storm I felt the boat rising to a particularly large swell. At some point I realized that this wave had come from a point some 30 to 40 degrees off our starboard bow. At the top of the wave, after the anchor rode had stretched out and we were being pulled through the crest, something happened and the tension on the rode was suddenly released. Surrender free fell backwards down the face of the wave, and upon landing was completely submerged. Sometime during this fall one of the forward salon windows was broken. After assuring myself that the boat was still upright, I took stock of our situation. The main cabin had three feet of water in it. All of the items stowed on the starboard side of the boat were now on the port side. Upon going topside, I found that our decks had been swept clean of all stowed gear, including items that had been secured with heavy webbed strapping. I nailed a piece of plywood, with a closed cell foam gasket secured to one side, over the broken window. Next I went forward and cut loose the sea anchor bridles because the boat was broadside to the swell and there was no appreciable tension on the rode, and I assumed that the sea anchor was gone. I did this so that the rode would not foul our prop or rudder as my intention was to run down swell and deploy drogues. In retrospect, this was a poor decision. I did not consider the possibility that the anchor was tumbled and/or fouled. All I could think of was not spending one more moment than necessary with Surrender broadside to those huge seas.

While I unlashed the helm, I made my next mistake. I attempted to start the engine for maneuverability without checking the engine room. Apparently the starter had gotten wet and it immediately shorted out causing billowing clouds of smoke to emerge from the engine room. At the same time I realized that the helm was not responding and when I inspected the rudder post my worst fears were confirmed. The two inch bronze post had snapped below the steering quadrant. It appeared to have twisted like a piece of plastic almost 90 degrees before breaking. There was less than half an inch of mangled post left to work with - far less than that needed for my emergency tiller to attach to. The next eighteen hours passed in a blur. We bailed the boat out with buckets, as the books and food on the cabin sole of the salon turned the water into a thick gruel that foreclosed the use of either our electric or hand pumps. The wind had subsided to fifty knots, and the seas to the 30 foot range by this time, and a small amount of headsail allowed Surrender to ride hove-to quite comfortably. By the end of this period I was able to jury rig a steering quadrant to the rudder post utilizing a modified clamp-on quadrant from an Alpha auto pilot, and we got back underway. The next five days were spent limping into Humboldt Bay fighting the cold (we had no dry cloths or blankets) and our dwindling supply of amps.

Better decisions would have left us with an answer as to whether some part of the sea anchor system had failed, or if the sea anchor had merely been tumbled and/or fouled, and if so, whether it might have eventually recovered and restored its pull. In any event, I have never traveled offshore since without two complete sea anchor rigs aboard, and would never hesitate to recommend their use for rest, repairs, or as a defensive storm tactic. I consider it the single most important tool we carry.

File S/T-18, obtained from Steve and Cheryl Bow, Auckland NZ. - Vessel name Labyrinth, hailing port Auckland, Searunner trimaran designed by Jim Brown, LOA 40' 10" x Beam 23' 6" x Draft 6' 11" (3' 6" board up) x 7.5 Tons - Sea anchor: 28-ft. Diameter Australian army cargo parachute on 400' x 3/4" nylon three strand tether and bridle arms of 90' each, with 5/8" galvanized swivel - Partial trip-line - Deployed in a storm in deep water about 270 miles south of Kermadec Islands with winds of 50-60 knots and seas of 30-35 ft. - Vessel's bow yawed 10° - Drift was 6.2 n.m. during 41 hours at sea anchor.

 

Steve and Cheryl Bow cruised the world aboard their 40-ft. Searunner Labyrinth. On 15 June 1995 (a year after the Queen's Birthday storm) they left Auckland and headed north for Tonga. Two days later they ran into a Force-10 storm about 270 miles south of the Kermadecs. Transcript:

We are a two-handed husband and wife crew. It was our plan to leave NZ on the back of a low that was at that time centered near Mt. Taranaki. Following it was a huge high over Australia and the winds between the two promised fair sailing. No fronts or depressions were forecast or expected from the coming weather. Our first days run was a rolly 155 miles broad reach in a 30 knot SW breeze and we were feeling very happy about things until we discovered water in the bilge at 2200 hrs on the 16th June. A porthole under the wingdeck had blown in and was leaking considerably. We effected a temporary repair and that took us through to daybreak.

At 0800 hrs we changed course and ran off before the wind for 6 hours while I epoxied the portholes closed with underwater epoxy. While we were running off, the latest weatherfax showed that a rapidly deepening low had formed north of Sydney and was heading our way - fast. If we hadn't had to run off to make the repairs we would have been OK, but as it was we were right in its path. Knowing that we were in for a rough night I went to bed, leaving Cheryl to do a long watch so that I would be fresh for the evening. When I awoke at 1800 hrs the winds were gusting over 30 knots from the NE and Cheryl had hove-to. We had two reefs in the main and the stays'l set; at this point the boat was comfortable despite the worsening seas and we settled down to sit it out. The 2000 hrs fax showed a second rapidly deepening low had formed behind the first.

Between 1400 and 1930 hrs the barometer dropped from 1005 bar to 998 bar. When the winds reached 50 knots and the barometer was still dropping we had to make the decision - run off, or set the parachute. It was 1930 hrs and very dark, we could see the approaching seas only by the foam as they broke, and the spray was being driven horizontally by the wind. The seas were still building and had reached the unstable stage, with steep faces and rolling crests. We carry a SEABRAKE on board which was set up ready to go, however we opted to set the parachute for two reasons: 1) We were both very tired and probably not up to spending a considerable time helming a running yacht in steep seas; and 2) The NE wind would have been driving us back towards the North Island of NZ. With further depressions developing and no early respite expected, the parachute was selected as the better option.

We set the parachute. We had never set it before, however I had read all the information I could acquire and had watched the video prepared by Para-Tech. It had been assembled as per their instructions, complete with one of their deployable storage bags. It was deployed over the weather bow while still hove-to, and worked like a charm. It was gusting 60 knots and more by the time we had it set, and it was difficult to see or work on deck because of the driven spray. As the tension went onto the tether we were swung gently around bow to and then sat there. The hard part was getting the stays'l and main down and under control in the high winds. The centerboard had already been pulled up.

At 2400 hrs the barometer had dropped to 993 bar and the wind speed was rarely below 60 knots. The motion of the boat was good, just a steady rise and fall to the waves with an occasional loud BANG! as a cross swell broke against the hulls. Despite my previous fears of excessive strain on the yacht the bows were NEVER pulled through any of the breaking crests, instead rising up and over them. There was tremendous strain on the bridle and tether, which "hummed" at times. Despite the noise the motion was easy enough for us to get sleep and cook between watches.

Waves continued to break on either side of the yacht, but we appeared to sit in a "slick" behind the parachute where there was only foam. We rigged nylon chafe protection on the bridle near exposed metalwork on the yacht and I checked for chafe every hour, both there and at the snatchblocks on the bows. At the end of 41 hours we still did not have any chafe. A mistake I made was in relying on the hydraulic steering ram to hold the rudder amidships. The force on the rudder from cross swells and rogue waves was substantial enough to drive the hydraulic ram to the end of its travel, and the rudder hard over. This was cured by shackling sheets [ropes] direct to the rudder and winching/cleating it off amidships.

We sat to the parachute for 41 hours; the wind went up and down averaging 45 knots and sometimes dropping below 30 knots. At 1230 hrs on the 19th June the wind was still 30 knots but had backed to NW. We opted to pull up the parachute and make a run for it north to try and get above the depressions. All went well retrieving the chute except that just as I was about to pull it in over the side of the boat the retrieval line ripped off the apex of the parachute and the chute filled again! We were drifting broadsides at the time and making quite a bit of way. I nearly got pulled over the side and lost most of the skin off my hands while trying to re-cleat the tether. This could not have happened with a purpose-built sea anchor! A 28 ft diameter parachute is almost impossible to retrieve in those conditions with no retrieval line and only two crew. We tried for over two hours and in the end I had to cut it free.

If we had known what we would face for the next 48 hours we would have stayed on the chute. We started off hard-on into the wind which was averaging 25-30 knots. This became a tight reach as it was more comfortable. Seas were rough and confused and repeatedly broke against the hulls.... Each time we hit one we would stop dead in our tracks. The noise was incredible and with the front of the boat continually getting swept by the seas I was worried that something would get broken if we didn't slow down (it turned out that we did break a stringer in the forward section of the stbd float).

On 21st of June we finally ran out of the weather. Incredibly a fourth low had formed and taken the same path as the other three, but by this time we had climbed out above it. We would never put to sea for an ocean passage again without a parachute.
