When I was an engineering student in college, we built concrete canoes and raced them against other universities. As a matter of fact, we raced at lake Norman in Charolette, NC. UNCC hosted the event. It was agreat excuse to have a fun and a big party. That was a long time ago though. Catamarans would have been a lot more fun, but I agree, who would have the budget? What about concrete catamarans? They make ferro-cement sailboats. Sounds like an engineering challenge and fun to me.
