Oh sorry I had thought this sub actually was for use and not for show. Sad really
Considering Hunley was Civil War tech and could Dive more than a few feet then that is no excuse. But then again this is for a silly race. What is a better use for funds is a sub that can take college students to good depths to do science while not relying on the short ranges of simple batteries. A human recharged sub is a great idea in my view.
Any plans to build a good sub?
