I've noticed these cats on YouTube for a few years now and I think they're the perfect upgrade from a beachcat. Unfortuanately it looks as if there's only a small fleet in Thailand but are licensed to be built in the US. 50-70grand without sails isn't bad for a new boat.
Some cool vids, first one shows self righting feature
