Matching a deep vee Larson FX 1750 DC O/B 2013 against a modified vee Larson LX 620 SF O/B 2012 means you're likely deciding between two genuinely 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 FX 1750 DC O/B 2013 at 17,4 ft versus Larson LX 620 SF O/B 2012 at 16,2 ft. Weight tells a clearer story for trailering families: the Larson FX 1750 DC O/B 2013 tips the scales at 2 133 lbs — 2 018 lbs more than the Larson LX 620 SF O/B 2012 at 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 150 hp, the Larson FX 1750 DC O/B 2013 has a 60-hp advantage over the Larson LX 620 SF O/B 2012's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 22 gal and 19 gal — so range won't be a tiebreaker here.

Both boats are rated for 6 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.

At this size, power-to-weight ratio matters more than outright horsepower. The Larson LX 620 SF O/B 2012 comes in at 1 lbs per hp versus 14 lbs per hp for the Larson FX 1750 DC O/B 2013. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
