Notes

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
