I just need to raise 496,000 usd and its mine! I have the first 1000 down. Man it would be so cool to have a submarine, I would knock out all the walls and turn it into a house boat if I owned one. It would be so cool to cruize around in. I would have to have lawn chairs on the deck, bolt them down (if possible).

The Mi-24 looks like more fun.

http://www.b-americanboats.com/mi-24.html yeah that looks cool too. But a submarine would still be a nice house boat, a minesweaper would too
