we should be able to design our own boats, and i'm not talking about paint jobs, i mean real design, like the lenght, weight, keel placement, sails etc.
like this cool flight simulator http://www.x-plane.com/ X-plane, that actually calculates realtime how the plane will move based on the design of aircraft.
that realtime thing is version 3 feature, but it would help if we could get more boats...
