There are at least 6 other opportunities after clearing the beach (and hut #1) to gain building experience. It is possible to get master builders after the beach, but it never hurts to get a head start. Don't wait to long to begin though, or you may run into food supply issues.

Who knows, maybe in a later version the villagers will be able to enjoy fine aquatic activities such as surfing, snorkeling, an parasailing. I can almost see the Golden Child flying the hull on a 16' catamaran. Oh well, we can dream, no?
