The Larson LX 180 S O/B 2013 is a deep-V design and the Larson LX 950 I/O 2012 is a modified-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

On paper these two are close siblings in the size department - Larson LX 180 S O/B 2013 at 18,5 ft versus Larson LX 950 I/O 2012 at 19,4 ft. Weight tells a clearer story for trailering families: the Larson LX 950 I/O 2012 tips the scales at 2 700 lbs - 521 lbs less than the Larson LX 180 S O/B 2013 at 2 179 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 220 hp, the Larson LX 950 I/O 2012 has a 70-hp advantage over the Larson LX 180 S O/B 2013's 150-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 30 gal and 30 gal - so range won't be a tiebreaker here.

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.
