Both the Larson 180 Sport I/O 2008 and the Larson LXi 288 I/O 2008 are modified-V designs, both built in fibreglass, 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 Larson LXi 288 I/O 2008 measures 29,0 feet overall (2008), giving it roughly 12,0 additional feet of deck space compared to the Larson 180 Sport I/O 2008 at 17,0 feet (2008). Weight tells a clearer story for trailering families: the Larson LXi 288 I/O 2008 tips the scales at 6 225 lbs - 3 850 lbs less than the Larson 180 Sport I/O 2008 at 2 375 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 420 hp, the Larson LXi 288 I/O 2008 has a 230-hp advantage over the Larson 180 Sport I/O 2008's 190-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

Both boats are rated for 8 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.
