Both the Harris Flotebote Grand Mariner 250 2012 and the Harris Flotebote Super Sunliner 200 LTD 2009 are pontoon designs, the first built in fibreglass and the second in aluminium, so 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?

Size is the most obvious dividing line here. The Harris Flotebote Grand Mariner 250 2012 measures 26,7 feet overall (2012), giving it roughly 5,7 additional feet of deck space compared to the Harris Flotebote Super Sunliner 200 LTD 2009 at 21,0 feet (2009). Weight tells a clearer story for trailering families: the Harris Flotebote Grand Mariner 250 2012 tips the scales at 3 546 lbs - 1 431 lbs more than the Harris Flotebote Super Sunliner 200 LTD 2009 at 2 115 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 115 hp, the Harris Flotebote Super Sunliner 200 LTD 2009 has a 113-hp advantage over the Harris Flotebote Grand Mariner 250 2012's 2-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 Super Sunliner 200 LTD 2009 is rated for 13 passengers, while the Harris Flotebote Grand Mariner 250 2012 caps at 2. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Harris Flotebote Super Sunliner 200 LTD 2009 could be the deciding factor.
