When two boats share the same hull type — in this case both the Montego Bay Pontoons F8518 2013 and the Montego Bay Pontoons F8520 PT BK 2013 are pontoon designs with aluminum construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.
