The Larson Cabrio 274 2011 has the bigger tank at 85 gallons, versus 23 gallons on the Larson SEi 180 Fish Series O/B 2006. That 62-gallon difference translates to roughly 186–310 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Yes — both the Larson Cabrio 274 2011 and the Larson SEi 180 Fish Series O/B 2006 are built by Larson.

Detailed Evaluation & Buyer Recommendation

Larson Cabrio 274 2011 vs Larson SEi 180 Fish Series O/B 2006 — Same Brand, Different Boat

Matching a deep vee Larson Cabrio 274 2011 against a modified vee Larson SEi 180 Fish Series 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 Cabrio 274 2011 measures 28,0 feet overall (2011), giving it roughly 11,0 additional feet of deck space compared to the Larson SEi 180 Fish Series O/B 2006 at 17,0 feet (2006). At 6 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 Cabrio 274 2011 carries a rated maximum of 400 hp. Engine data for the Larson SEi 180 Fish Series O/B 2006 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Larson Cabrio 274 2011 carries 85 gallons versus 23 gallons in the Larson SEi 180 Fish Series O/B 2006. 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 274 2011 is rated for 8 passengers, while the Larson SEi 180 Fish Series 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 Cabrio 274 2011 could be the deciding factor.

Bottom line: Choose the Larson Cabrio 274 2011 if your priority is putting more people on the water — it handles 8 passengers and at 28,0 ft it has the deck room to back that rating up comfortably. The Larson SEi 180 Fish Series 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.
