You will need a strong electric motor to power a boat that size. Plan
on a 24V as a minimum. You mention lakes and bays. If the bay is in
the ocean, you will want to spend a bit more for a sal****er trolling motor.

What about a jon boat? They are very stable and would accommodate a
bimini top very well.

OK. This means I should look in the range of 16-ft to 18-ft boat. I
will look around to see if I can find some used boats that match the
criteria.

Thanks.
