My dad and I built one back in the 60's. We got the plans from Popular Mechanics magazine. Ours was plywood with small Morris Fairbanks Diesel , was mom ever mad when we showed up with that, money was tight back then with four sisters. We started in Waveland Miss ,and after the second big hurricane Camel our house was lost and finished it in Fla. Those were the good old days on the Indian river fishing just about every night.
