When two boats share the same hull type — in this case both the Harris Flotebote Grand Mariner SEL 250 2013 and the Harris Flotebote Sunliner 240 2008 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?

On paper these two are close siblings in the size department — Harris Flotebote Grand Mariner SEL 250 2013 at 27,3 ft versus Harris Flotebote Sunliner 240 2008 at 25,0 ft. Weight tells a clearer story for trailering families: the Harris Flotebote Grand Mariner SEL 250 2013 tips the scales at 4 151 lbs — 1 907 lbs more than the Harris Flotebote Sunliner 240 2008 at 2 244 lbs. 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.

The power gap is worth calling out. Rated to 430 hp, the Harris Flotebote Grand Mariner SEL 250 2013 has a 280-hp advantage over the Harris Flotebote Sunliner 240 2008's 150-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

Both boats are rated for 16 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
