Larson Cabrio 274 2011 vs Larson SEi 180 O/B 2004 - Boat Spec Comparison

Q: Which is easier to trailer — the Larson Cabrio 274 2011 or the Larson SEi 180 O/B 2004?

For trailering, the Larson Cabrio 274 2011 has the edge at 6 lbs dry weight versus 15 lbs for the Larson SEi 180 O/B 2004. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.

Q: Which boat can handle a bigger outboard?

The Larson Cabrio 274 2011 is rated to a maximum of 400 hp, giving it the larger power ceiling. The Larson SEi 180 O/B 2004 tops out at 150 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.

Q: How many people can each boat hold?

The Larson Cabrio 274 2011 is Coast Guard rated for 8 passengers, while the Larson SEi 180 O/B 2004 is certified for 5. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.

Q: Which boat is wider, and does it affect trailering?

The Larson Cabrio 274 2011 measures 102" wide, compared to 93" for the Larson SEi 180 O/B 2004. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.

Q: Which boat has the larger fuel tank — the Larson Cabrio 274 2011 or the Larson SEi 180 O/B 2004?

The Larson Cabrio 274 2011 has the bigger tank at 85 gallons, versus 23 gallons on the Larson SEi 180 O/B 2004. That 62-gallon difference translates to roughly 186–310 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Larson Cabrio 274 2011 and Larson SEi 180 O/B 2004 from the same manufacturer?

Yes — both the Larson Cabrio 274 2011 and the Larson SEi 180 O/B 2004 are built by Larson. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.

Detailed Evaluation & Buyer Recommendation

Larson Cabrio 274 2011 vs Larson SEi 180 O/B 2004 — Same Brand, Different Boat

The Larson Cabrio 274 2011 vs Larson SEi 180 O/B 2004 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

The power gap is worth calling out. Rated to 400 hp, the Larson Cabrio 274 2011 has a 250-hp advantage over the Larson SEi 180 O/B 2004's 150-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Larson Cabrio 274 2011 carries 85 gallons versus 23 gallons in the Larson SEi 180 O/B 2004. 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 O/B 2004 caps at 5. 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 O/B 2004 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
