When two boats share the same hull type — in this case both the Harris Flotebote Sunliner 180 2010 and the Harris Flotebote Sunliner 240 2013 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?

Size is the most obvious dividing line here. The Harris Flotebote Sunliner 240 2013 measures 25,8 feet overall (2013), giving it roughly 7,8 additional feet of deck space compared to the Harris Flotebote Sunliner 180 2010 at 18,0 feet (2010). Weight tells a clearer story for trailering families: the Harris Flotebote Sunliner 240 2013 tips the scales at 3 464 lbs — 1 360 lbs less than the Harris Flotebote Sunliner 180 2010 at 2 104 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 Sunliner 240 2013 tops out at 2 hp. Engine specs for the Harris Flotebote Sunliner 180 2010 aren't listed — confirm with a dealer before selecting an outboard.Both carry nearly identical fuel loads — 5 gal and 5 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Harris Flotebote Sunliner 180 2010 is rated for 9 passengers, while the Harris Flotebote Sunliner 240 2013 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 Sunliner 180 2010 could be the deciding factor.
