Frequently Asked Questions

Is the Allied Seawind 30 a good offshore cruiser?

Yes — by design and by the numbers. The long keel, heavy displacement/length ratio of 387, comfort ratio near 37 and a capsize screening formula of 1.62 (comfortably under the offshore threshold of 2) all point to a slow but sea-kindly passage-maker. It needs a decent breeze to move (SA/D 15.4), and the 34% ballast ratio rewards early reefing, but in a blow this ketch is exactly where it belongs.

How many Allied Seawind 30s were built?

Allied Boat Company built 161 Seawinds between 1962 and 1982 in the United States, to Thomas Gilmer's design. The original boats were masthead ketches; the later Seawind II broadened the options with cutter and occasionally sloop rigs, so survey the rig carefully when comparing individual boats on the used market.

What are the key specifications of the Allied Seawind 30?

Length overall 30'6" (9.30 m) on a 24'0" waterline, beam 9'3", draft 4'2", displacement 12,000 lbs with 4,200 lbs of ballast, and 425 ft² of sail on the masthead ketch rig. The fiberglass hull carries a long keel with transom-hung rudder and a theoretical hull speed of about 6.7 knots — classic heavy-cruiser numbers.
