Q: Which is easier to trailer — the Larson Cabrio 290 2004 or the Larson SEi 180 O/B 2004?

For trailering, the Larson Cabrio 290 2004 has the edge at 9 lbs dry weight versus 15 lbs for the Larson SEi 180 O/B 2004.

Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.

The Larson SEi 180 O/B 2004 has a documented max rating of 150 hp. Engine specifications for the Larson Cabrio 290 2004 were not available in our database — check the OEM spec sheet or manufacturer's website for confirmation.

Q: How many people can each boat hold?

The Larson Cabrio 290 2004 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 290 2004 measures 114" 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 290 2004 or the Larson SEi 180 O/B 2004?

The Larson SEi 180 O/B 2004 has the bigger tank at 23 gallons, versus 1 gallons on the Larson Cabrio 290 2004. That 22-gallon difference translates to roughly 66–110 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Larson Cabrio 290 2004 and Larson SEi 180 O/B 2004 from the same manufacturer?

Yes — both the Larson Cabrio 290 2004 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

The Larson Cabrio 290 2004 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.
