Larson FX 2050 DC O/B 2013 vs Larson SEi 180 Ski Fish 2009 — Same Brand, Different Boat

Matching a deep vee Larson FX 2050 DC O/B 2013 against a modified vee Larson SEi 180 Ski Fish 2009 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 FX 2050 DC O/B 2013 measures 20,2 feet overall (2013), giving it roughly 3,2 additional feet of deck space compared to the Larson SEi 180 Ski Fish 2009 at 17,0 feet (2009). Weight tells a clearer story for trailering families: the Larson FX 2050 DC O/B 2013 tips the scales at 2 768 lbs — 2 503 lbs more than the Larson SEi 180 Ski Fish 2009 at 265 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 FX 2050 DC O/B 2013 carries a rated maximum of 250 hp. Engine data for the Larson SEi 180 Ski Fish 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 FX 2050 DC O/B 2013 carries 35 gallons versus 23 gallons in the Larson SEi 180 Ski Fish 2009. 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 FX 2050 DC O/B 2013 is rated for 7 passengers, while the Larson SEi 180 Ski Fish 2009 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Larson FX 2050 DC O/B 2013 could be the deciding factor.

Bottom line: Choose the Larson FX 2050 DC O/B 2013 if your priority is putting more people on the water — it handles 7 passengers and at 20,2 ft it has the deck room to back that rating up comfortably. The Larson SEi 180 Ski Fish 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
