When two boats share the same hull type — in this case both the Harris Flotebote Grand Mariner 220 2010 and the Harris Flotebote Grand Mariner SL 250 (3-Tube) 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?

On paper these two are close siblings in the size department — Harris Flotebote Grand Mariner 220 2010 at 22,0 ft versus Harris Flotebote Grand Mariner SL 250 (3-Tube) 2010 at 25,0 ft. Weight tells a clearer story for trailering families: the Harris Flotebote Grand Mariner 220 2010 tips the scales at 2 805 lbs — 2 773 lbs more than the Harris Flotebote Grand Mariner SL 250 (3-Tube) 2010 at 32 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 (3-Tube) 2010 tops out at 300 hp. Engine specs for the Harris Flotebote Grand Mariner 220 2010 aren't listed — confirm with a dealer before selecting an outboard.
