The Wharram community often debates what size cat is required to cross an open ocean. In variably it is something greater than 30 feet. The Tiki 26 is thought of as a 'round the bay' multi-day sailor not a boat to cross oceans in. Wharram sailors have disproved that notion making successful voyages. Now take that concept, lop off a few feet and make it a proa instead of a cat. Max and Manu Berque have gone for it. Of course if you read about these two you will see they always do.
