File S/C-2, obtained from William E. Masters, Columbus OH. - Vessel name Rhayader, Snowgoose catamaran, designed by Prout, LOA 37' x Beam 16' x Draft 2'6" x 6 Tons - Sea anchor: 12-ft. Diameter Para-Tech on 300' x 3/8" nylon three strand tether and bridle arms of 12' each, with 5/8" galvanized swivel - Full trip line - Deployed in a whole gale in the Bay of Biscay, and also in a low system near the Bahamas with winds of 35-60 knots and seas of 20-30 feet. - Vessel's bow yawed 10° - Drift was estimated to be 12 n.m. during 66 hours at sea anchor.

Rhayader, a handsome 37-ft. "Snowgoose" designed and built by the Prout brothers, was purchased in England and sailed across the Atlantic in April 1987. The owner, William Masters, used a 12-ft. diameter Para-Tech sea anchor in a gale in the infamous Bay of Biscay. Winds were then sustained at 45 knots, gusting to 60. The sea anchor was used again about a year later when Rhayader ran into a low system stalled off Bermuda. When a low system gets stalled for an extended period of time, even if it is only packing thirty knot winds it will eventually begins to generate huge waves and swells. On the DDDB form that Masters sent back he indicated that some of the combined seas were higher than 30 ft. On this second occasion Rhayader was tethered to the sea anchor for 66 hours. Transcript:

During the 66 hour period, the seas and wind averaged 040° True. Our drift was 262° True, probably tidal set onto the Bahamas Banks. Also, in April of '87 while sailing to the Canary Islands from England, we deployed the para-anchor off the Continental Shelf, depth unknown. Winds were easterly, sea from the northwest. Nasty. Seas were short and steep (200-250' crest to crest. Winds were steady 45 knots, gusts to 60 knots. Hove to the para-anchor for 22 hours. Drift was 2 n.m. west. Thanks, para-anchor, and of course the Casanovas. I wouldn't leave port without it.
