When two boats share the same hull type — in this case both the Harris Flotebote Grand Mariner SL 250 (2-Tube) 2010 and the Harris Flotebote Sunliner 240 2011 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 SL 250 (2-Tube) 2010 at 25,0 ft versus Harris Flotebote Sunliner 240 2011 at 24,0 ft. Weight tells a clearer story for trailering families: the Harris Flotebote Grand Mariner SL 250 (2-Tube) 2010 tips the scales at 2 963 lbs — 128 lbs more than the Harris Flotebote Sunliner 240 2011 at 2 835 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 Harris Flotebote Grand Mariner SL 250 (2-Tube) 2010 carries a rated maximum of 175 hp. Engine data for the Harris Flotebote Sunliner 240 2011 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.

Both boats are rated for 13 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.
