Well..................I built it with a very good friend. He is way more talented than I am for carpentry and assembly. We worked together and I learned a lot.
I just started with two 25 inch diameter pontoons, had them shortened, and then built the frame, and kept going. Great stereo, and acceptable drink holders and good to go. I wanted it to fit in the Florida garage. The trailer has a swing away tongue and it misses the front garage door by 2 inches. The tops of the seats miss the opening in the garage by 1 inch. It steers with a stick between the two front seats.
The trim around the outside of the deck came from Bennington and the dashboard is really a WalMart cutting board. (I noticed it in the store when I was shopping for noodles)
The second picture is after we put the frame and deck on it. (But there was plenty more work to do)
