Driver age: most companies need the driver to be 21 or 25 with a valid ID.
Pontoon or tritoon: both are flat, stable party boats. A tritoon has a third tube, so it rides smoother and carries more power.
Where you can go: rentals stay on the Intracoastal Waterway and the rivers, not the ocean. Ask about sandbars and swimming spots when you pick up the boat.
No one wants to drive? Several companies rent the same boat with a captain.
