When two boats share the same hull type — in this case both the Harris Flotebote Grand Mariner SEL 250 2012 and the Harris Flotebote Super Sunliner 250 LX 2009 are pontoon designs with fiberglass 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 2012 at 27,3 ft versus Harris Flotebote Super Sunliner 250 LX 2009 at 26,0 ft. Weight tells a clearer story for trailering families: the Harris Flotebote Grand Mariner SEL 250 2012 tips the scales at 3 537 lbs — 912 lbs more than the Harris Flotebote Super Sunliner 250 LX 2009 at 2 625 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 175 hp, the Harris Flotebote Super Sunliner 250 LX 2009 has a 172-hp advantage over the Harris Flotebote Grand Mariner SEL 250 2012's 3-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Harris Flotebote Grand Mariner SEL 250 2012 is rated for 225 passengers, while the Harris Flotebote Super Sunliner 250 LX 2009 caps at 16. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Harris Flotebote Grand Mariner SEL 250 2012 could be the deciding factor.
