Any Joel White Marsh Cat 15 owners?

[Buddy Sharpton]

I'm trying to finish up a refit on a boat built in early 1989 and as it's required for scoring by the race committee, I want to put a plausible sail number on her. The design is dated 1987, and as far as I know Wooden Boat is the only source of the plans. But a sets of plans sold is likely more than boats built. Does anybody out there have one of these nifty boats or know of the whereabouts of same? I'd appreciate your help in locating sister boats. Many Thanks.
