Notes

The SEAWIND II was introduced as the successor to the original SEAWIND (1962). It was over a foot longer, over a foot wider, had more sail area, and weighed an additional 2100 pounds. The price was also significantly higher and the builder continued to build both versions until 1982.
Also available as a cutter (11 delivered) or sloop (5).
