When two boats share the same hull type — in this case both the Larson 1850 LX 2010 and the Larson LXi 218 2009 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 LXi 218 2009 at 21,0 ft. Weight tells a clearer story for trailering families: the Larson LXi 218 2009 tips the scales at 3 735 lbs — 1 360 lbs less than the Larson 1850 LX 2010 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 Larson 1850 LX 2010 carries a rated maximum of 190 hp. Engine data for the Larson LXi 218 2009 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Larson LXi 218 2009 carries 34 gallons versus 23 gallons in the Larson 1850 LX 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Larson LXi 218 2009 is rated for 9 passengers, while the Larson 1850 LX 2010 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Larson LXi 218 2009 could be the deciding factor.
Bottom line: Choose the Larson LXi 218 2009 if your priority is putting more people on the water — it handles 9 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Larson 1850 LX 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
