One of the class 4 competitors this year is Yellowthing (aka Meade Gougeon). Meade is sailing two-up this year with his brother Jan. I don't know how old these guys are, but they are past the retirement age if you catch my meaning.
Here's a cool time lapse video of his new i550 going together this year. I'm certainly looking forward to seeing this boat on the beach at Ft. Desoto. However, I expect I won't see them again until the finish. These guys are my pick to win Class 4 this year. I want to be just like them when I grow up.
