Redu,
The figures you listed are correct. This little boat is 15ft 3inches long, 60inch beam, total weight including batteries 500lbs, and then plus a 190lb operator = 690lbs. I should note that this test was using a high pitch prop (12x12) vs. the standard prop (12x10).

Still using a set of heavy AGM's for testing, so nothing fancy about the batteries. For the production model we will build this boat in the Kevlar version with a small remote steering console. This test boat is good old fiberglass.
