Here's a diagram of my plans for the boat.
I'm gonna have three seats in it, one on the front deck, one in the middle on a short pedestal, and one on the rear bench. The one on the rear bench I am going to use the moveable pin base for and put two mounting plates on either end of the rear bench so I can move it to one side for steering, or the other for fishing. Also had to put in plenty of cup holders ! (LOL) Storage in the rear is for fuel tank and whatever else. I am mounting two batteries under the front deck up against the sides so I will still have some storage there too.
