When two boats share the same hull type — in this case both the Larson 1850 LX 2010 and the Larson LX 710 I/O 2012 are modified vee designs with fiberglass 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?

On paper these two are close siblings in the size department — Larson 1850 LX 2010 at 18,8 ft versus Larson LX 710 I/O 2012 at 17,1 ft. Weight tells a clearer story for trailering families: the Larson 1850 LX 2010 tips the scales at 2 375 lbs — 2 171 lbs more than the Larson LX 710 I/O 2012 at 204 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 190 hp, the Larson 1850 LX 2010 has a 55-hp advantage over the Larson LX 710 I/O 2012's 135-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Larson 1850 LX 2010 carries 23 gallons versus 19 gallons in the Larson LX 710 I/O 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 7 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.
