When two boats share the same hull type — in this case both the Harris Flotebote Grand Mariner SEL 250 2013 and the Harris Flotebote Super Sunliner LX 250 2010 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?
