Detailed Evaluation & Buyer Recommendation

Larson Cabrio 310 2011 vs Larson SEi 180 LX 2009 — Same Brand, Different Boat

Matching a deep vee Larson Cabrio 310 2011 against a modified vee Larson SEi 180 LX 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 Cabrio 310 2011 measures 31,0 feet overall (2011), giving it roughly 14,0 additional feet of deck space compared to the Larson SEi 180 LX 2009 at 17,0 feet (2009). Weight tells a clearer story for trailering families: the Larson SEi 180 LX 2009 tips the scales at 2 365 lbs — 2 261 lbs less than the Larson Cabrio 310 2011 at 104 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 Cabrio 310 2011 carries a rated maximum of 320 hp. Engine data for the Larson SEi 180 LX 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 SEi 180 LX 2009 carries 23 gallons versus 16 gallons in the Larson Cabrio 310 2011. 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 Cabrio 310 2011 is rated for 9 passengers, while the Larson SEi 180 LX 2009 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Larson Cabrio 310 2011 could be the deciding factor.

Bottom line: Choose the Larson Cabrio 310 2011 if your priority is putting more people on the water — it handles 9 passengers and at 31,0 ft it has the deck room to back that rating up comfortably. The Larson SEi 180 LX 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
