Ahhh...that explains it. Do you know about what percentage of the fleet is wood vs. glass? Looks like a good turnout of both types.

There are not too many people here in the US who have the time/skill/knowledge to build a good wooden boat any more. There are a few companies that sell wooden kits for kayaks, stitch and glue, that have become popular but they don't offer any catamaran type kits. I emailed one of them to ask why not and he said it would be too hard to convert the tortured ply method plans to stitch and glue plans and that to build a tortured ply boat would be much harder than what they do.
