S/T-17

Trimaran, Kantola

34' x 24' x 3 Tons

28-Ft. Dia. Parachute Sea Anchor

Force 9-10 Conditions

File S/T-17, obtained from Richard R. Barrie, Van Nuys, CA. - Vessel name Fifth Fox, hailing port Channel Islands, CA, trimaran designed by Jay Kantola, LOA 34' x Beam 24' x Draft 3' x 3 Tons - Sea anchor: 28-ft. Diameter C-9 military class parachute on 400' x 3/4" nylon three strand tether and bridle arms of 100' each, with 3/4" galvanized swivel - No trip-line - Deployed in a Pacific storm in deep water about 1000 miles west of Guadalajara, Mexico, with winds of 55-70 knots and seas of 20 ft. - Vessel's bow yawed 10° - Drift was estimated to be 12 n.m. during 72 hours at sea anchor.

Sailing to Los Angeles from Panama, Richard Barrie decided to take one long - 1000 mile - tack out to sea and back, avoiding the Pagagayos, Tehuantepeckers and other hazards that one ordinarily associates with the Central American coast. However, Fifth Fox ran into a storm well offshore. Transcript:

During the last week of May, 1984, my wife and I with our two daughters left the Las Perlas Islands in Panama, and headed back to California. The first two weeks of the trip north were idyllic, 15-20 knots beam reaching with the spinnaker and the Tiller-Master doing all the work. During the second week of June the wind gradually went northwest and increased.

Before noon on the second day of the wind shift, a strong gust hit us (we had put a reef in the main, but still had a 120 genoa up) and the lower after stay on the port side parted at deck level. My first thought was to deploy the parachute, fix the shroud and continue on. We deployed the chute off the stern [on the fly] going downwind without a trip line in moderate conditions. I fully expected to replace the lower shroud and continue on. While sitting to the chute during the first hour or so, I went up the mast with a new Sta-Lock attached to a new lower stay. While I was at the spreaders attempting to exchange the wire, the wind quickly increased from a steady 30-35 knots to a steady 50 knots with higher gusts, with the sea state increasing rapidly. I had never been seasick in all my life, yet I became nauseous. I could not continue with the work aloft so came down the mast and jury-rigged the lower at the deck with some wire clamps. That took the S-curve out of the mast so we could sail if the chute let go.

After sitting on the parachute anchor for a few hours, I was in the cockpit when a huge wave pushed the boat up to the crest and back on the rudder. The rudder had been locked in place amidships with the Tiller-Master. In the middle of this particularly large cresting wave, I heard a sickening crack and looked down and saw the tiller head starting to swing independently of the tiller. It was very apparent what was wrong. Fortunately there was a hole in the rudder blade itself, so with a stout line tied to the port float near the transom, I dove in the sea and rove this line through the rudder blade, with a knot on either side, then on to the starboard float. This action no doubt saved the rudder....

For the next three days we were anchored to the parachute, with the wind screaming and the waves cresting. While it was difficult to sleep soundly, we could at least sleep. As time wore on, it became apparent that we and the boat were safe, even with the wind flicking salt water bullets at us at 50 or 60 knots. The wind moderated to 35 knots after the third day and we cast off the lines and sailed up to the float and retrieved the parachute quite easily. Previously we had deployed the parachute with a trip line and it fouled rather quickly. I resolved then never to use a trip line again. I will now carry two parachutes for insurance.

I took star shots each evening and morning during our three day stay in this part of the ocean and was quite surprised to find that we moved only 12 miles in a southeasterly direction.

Sea Anchors on Trimarans

S/T-16 Trimaran, Kantola

Spirit of Tsitika of Victoria, BC. This Kantola trimaran uses a 24-ft. diameter surplus parachute to heave-to offshore. "...we opted to set the chute, rather than continue beating to windward in those conditions. As soon as we were deployed the wind increased to 45 kts. and gusting higher, with a steep, short chop (8-10 ft.) on top of a large westerly swell of about 12-15 ft." (Gary Cagné photo). S/T-16

Trimaran, Kantola

35' x 24' x 3 Tons

24-Ft. Dia. Parachute Sea Anchor

Force 8-9 Conditions

File S/T-16, obtained from Gary Cagné, Vancouver, BC. - Vessel name Spirit Of Tsitika, hailing port Victoria BC, trimaran, designed by Jay Kantola, LOA 35' 6" x Beam 24' x Draft 5' 6" (2' 6" board up) x 3 Tons - Sea anchor: 24-ft. Diameter military chest reserve on 300' x 9/16" nylon three strand tether and bridle arms of 50' each, with 5/8" stainless steel swivel - No trip-line - Deployed in a gale in deep water about 50 miles off the coast of Baja California with winds of 35-45 knots and seas of 12-15 ft. - Vessel's bow yawed 10° - Drift was estimated to be 9 n.m. during 17 hours at sea anchor.

 

There is a certain grace and elegance associated with Jay Kantola's designs that one has to see to appreciate. His boats tend to remind one of certain benign and beautiful birds that roam across vast oceans on great wings. Not the feisty, competitive, acrobatic Frigate bird, whose flying skills and prize-winning antics one might associate with one of Richard Newick's masterpieces, but perhaps the magnificent, gentle, white-winged, black-browed Albatross of the Southern Ocean.

At least this was Shane Victor's impression when he first saw Spirit Of Tsitika tied up in Santa Barbara harbor. Two months after visiting with him, Gary Cagné and his companion Claire ran into a gale off the coast of Baja California. Transcript:

On the way to Cabo San Lucas we discovered an incredible lagoon on the east side of Mag Bay, in which we spent several days lounging and hiking and bird watching. It's finally beginning to warm up a bit. Just left this morning with a nice offshore light westerly filling the new spinnaker we found at a thrift store in Santa Barbara for $25!

As you can see we finally had a good opportunity to use the parachute sea anchor, and we're ever happy we did. We had the wind on the nose for 24 hours or more with torrential rain the whole time, and with a long offshore tack we ended up 65 miles NW of Cape Lazaro (near Bahia Santa Maria) when the wind got up to 35 kts at 1500 hrs. So we opted to set the chute, rather than continue beating to windward in those conditions. As soon as we were deployed (the deployment bag worked fantastic) the wind increased to 45 kts and gusting higher, with a steep short chop (8-10 ft.) on top of a large westerly swell of about 12-15 ft.

The seas lengthened later on as the gale continued, enabling the bows to ride a bit higher. Initially they were picking up the tops of the [short, steep] waves and spraying the whole boat, pouring rain all the while and the barometer continuing to drop. Pretty easy ride once the waves began lengthening, and about 0300 next morning the wind eased off a bit and switched to SW 25-30. By first dawn we had a light westerly and very confused seas coming from various directions. We got underway after winching in the chute (very easy) and arrived safely, with no damage, later that night in Bahia Santa Maria. The next day we heard about Whistlin, a 37-ft. Searunner and several other boats that ended up having to power [jog] through the storm, suffering miscellaneous damage - mostly losing gear over the side and diesel problems. One monohull suffered a knockdown, and the group closer in to shore reported gusts to 60 kts! Whistlin has a surplus parachute on board but still needs to re-sew the shroud lines to it.

Note: When we retrieved the parachute, we found that the float line had twisted itself many times, and even part of it was caught in two of the parachute shroud lines. So we learned that it is necessary to have a swivel for the float line as well. Claire and I are feeling more confident now that we've had our first parachute sea anchor experience and know how well it works.
