You could be on the right track with the pontoon boat, by far it will give you the most open space with plenty of modifications to make you fish better. I'd stick with the pontoon and put an electric retractable ramp with some type of wireless control, get a trolling motor with a wireless remote like ipilot, two shallow water anchors that will help stability for rolling on board from shore/ramp. You could thin out or open up the outer caging more to have a better access to the water or fish. Add some rod holders for so you can grab something else like nets/pliers etc. Add a duck pole to help push off if you push into a berm or when you beach
