I agree that for what you want, 24' would be the minimum. We have a 20' Premier Horizon and it's perfect for us, but more than 5 or 6 people starts to get cramped. We have a 40 hp. motor and it will pull a tube, but you're not gonna be doing any aerobatics back there. I believe Premier was started by former Bennington employees. I really want a Bennington. IMHO, those are the Cadillac of pontoons.
