Sunfish
Why Sunfish?
There are more flashy and many specifically well designed boats to sail but this early 1970s hard chine, lanteen rigged boat is perhaps the most affordable and inclusive one design sailboats ever built.
What is most impressive is that simple to rig and race such that juniors as young as 9 yrs old and seniors well into their 80s who weigh as little as105 lbs. to over 200 lbs. can compete at a world class level. No other singlehanded boat can so closely level the playing field, making age, gender and size relative non issues. Families have been doing this for over 40 years.

The Sunfish Class provides perhaps the most widely attractive one design racing on a world class level.
As former world champions Eduardo Cordero and I feel compelled to support the Sunfish Class. particularly in that is how we met Aside from the competition, we both feel that many of our closest friends made over the years have become like family. Those relationships represent what Sunfish has meant to us and we hope that anything we might provide may help give others the opportunities the Sunfish Class has given us both.
