Larson LSR 2100 2013 vs Larson LX 850 Classic SF 2011 — Same Brand, Different Boat

Matching a deep vee Larson LSR 2100 2013 against a modified vee Larson LX 850 Classic SF 2011 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 LSR 2100 2013 at 21,1 ft versus Larson LX 850 Classic SF 2011 at 18,4 ft. Weight tells a clearer story for trailering families: the Larson LX 850 Classic SF 2011 tips the scales at 245 lbs — 218 lbs less than the Larson LSR 2100 2013 at 27 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 LX 850 Classic SF 2011 tops out at 225 hp. Engine specs for the Larson LSR 2100 2013 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Larson LX 850 Classic SF 2011 carries 23 gallons versus 3 gallons in the Larson LSR 2100 2013. 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 LSR 2100 2013 is rated for 8 passengers, while the Larson LX 850 Classic SF 2011 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Larson LSR 2100 2013 could be the deciding factor.

Bottom line: Choose the Larson LSR 2100 2013 if your priority is putting more people on the water — it handles 8 passengers and at 21,1 ft it has the deck room to back that rating up comfortably. The Larson LX 850 Classic SF 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.

The Larson LSR 2100 2013 is the longer of the two at 21,1 feet overall. The Larson LX 850 Classic SF 2011 comes in at 18,4 feet, making it roughly 2,7 ft shorter — a meaningful difference in deck room and overall on-water presence.
