When two boats share the same hull type — in this case both the Harris Flotebote Sunliner 180 2011 and the Harris Flotebote Sunliner 240 2009 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 2009 measures 25,0 feet overall (2009), giving it roughly 7,0 additional feet of deck space compared to the Harris Flotebote Sunliner 180 2011 at 18,0 feet (2011). Weight tells a clearer story for trailering families: the Harris Flotebote Sunliner 180 2011 tips the scales at 2 104 lbs — 2 080 lbs more than the Harris Flotebote Sunliner 240 2009 at 24 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 2009 tops out at 150 hp. Engine specs for the Harris Flotebote Sunliner 180 2011 aren't listed — confirm with a dealer before selecting an outboard.

For family outings this is probably the sharpest distinction between the two. The Harris Flotebote Sunliner 240 2009 is rated for 16 passengers, while the Harris Flotebote Sunliner 180 2011 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Harris Flotebote Sunliner 240 2009 could be the deciding factor.
