Hi Alan, the hull is 66 inches long, beam is 9 inches, the ballast tank is all metal construction, a nicad pack sits in the keel, the scale is 1/27th, price is 950, now that might make you sweat, but if you bought an engels boat and then bought the tools to put it together, ie pillar drill, etc, it bumps the price up, the vast majority of the construction is already done, the manual/cd that chris has put together even shows you how to solder, you could email chris at sheerlinesubs@btinternet.com, he has also upgraded the trafalgar by reducing the tophull weght and adding a nicad pack, i do have more pics i can send regards Pete
