Detailed Evaluation & Buyer Recommendation

Larson LSR 2100 2013 vs Larson SEi 180 Ski Fish O/B 2006 — Same Brand, Different Boat

Matching a deep vee Larson LSR 2100 2013 against a modified vee Larson SEi 180 Ski Fish O/B 2006 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.

Size is the most obvious dividing line here. The Larson LSR 2100 2013 measures 21,1 feet overall (2013), giving it roughly 4,1 additional feet of deck space compared to the Larson SEi 180 Ski Fish O/B 2006 at 17,0 feet (2006). At 27 lbs and 17 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The Larson SEi 180 Ski Fish O/B 2006 tops out at 150 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 SEi 180 Ski Fish O/B 2006 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 SEi 180 Ski Fish O/B 2006 caps at 6. 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 SEi 180 Ski Fish O/B 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
