500 Super Sport Crossover | Formula Boats
One heck of a boat, just pulling your chain!
Good luck with the pontoon. When I go that route, I will probably consider going small, like a "Bass Buggy" or similar, for ease of handling in my older years. I believe all that space could get addicting! Sounds like a fun project.
I missed 2 potential candidates already. A dose of patience is in order
The love for fishing is one of the best gifts you can pass along
