About the SEAWIND (ALLIED)
Originally designed for Kaiser Gale Force Yachts which sold the molds to Allied Boat Co. After changing the cabin top and port arrangement, the first boat appeared in 1962. Early builders under contract were Lunn Laminates of Port Washington, NY and F.L. Tripp & Sons, Westport, MA. (Allied eventually had it's own large plant in the Catskills, NY.) The SEAWIND was the first, as well as one of the last, boats built by Allied Boat Company. In 1978 it was brought back into production and actually built simultaneously with the newer SEAWIND II. Also offered with a sloop rig. (with mast stepped farther aft.) I: 35.58'/10.84m J: 13.16'/4.01m P: 31.83'/9.70m E: 14.25'/4.34m
Designed by Thomas Gillmer and built by Allied Boat Co. (USA) from 1962β1982, the Seawind is a robust 30.5 ft masthead ketch with 161 hulls produced. Its full/long keel and 12000.0 lb displacement provide a stable, traditional cruising platform, though owners frequently report significant maintenance challenges regarding the deck core and keel structure.
- Best for:
- This boat suits traditional coastal cruisers and those seeking a stable, slow-paced bluewater experience, particularly owners willing to commit to extensive structural maintenance and modern engine/electronics upgrades.
- Bluewater capability:
- With a low capsize ratio of 1.62, high displacement of 12000.0 lb, and a full/long keel, the Seawind is inherently stable and suitable for offshore passages, provided the critical structural integrity of the deck core and keel is verified.
- Comparables:
- Comparable boats include the Cal 30 and O'Day 30, which share similar displacement, full-keel designs, and masthead rigging configurations from the same era, offering similar stability and interior volume profiles.
