For trailering, the Larson Cabrio 370 2004 has the edge at 168 lbs dry weight versus 2 375 lbs for the Larson 180 Sport I/O 2007.

The Larson 180 Sport I/O 2007 is Coast Guard rated for 8 passengers, while the Larson Cabrio 370 2004 is certified for 6. 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 370 2004 measures 156" wide, compared to 88" for the Larson 180 Sport I/O 2007. 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.

The Larson Cabrio 370 2004 has the bigger tank at 266 gallons, versus 23 gallons on the Larson 180 Sport I/O 2007. That 243-gallon difference translates to roughly 729–1215 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Yes — both the Larson 180 Sport I/O 2007 and the Larson Cabrio 370 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 180 Sport I/O 2007 vs Larson Cabrio 370 2004 — Same Brand, Different Boat

The Larson 180 Sport I/O 2007 vs Larson Cabrio 370 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 Larson 180 Sport I/O 2007 carries a rated maximum of 190 hp. Engine data for the Larson Cabrio 370 2004 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 370 2004 carries 266 gallons versus 23 gallons in the Larson 180 Sport I/O 2007. 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 180 Sport I/O 2007 is rated for 8 passengers, while the Larson Cabrio 370 2004 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Larson 180 Sport I/O 2007 could be the deciding factor.

Bottom line: Choose the Larson 180 Sport I/O 2007 if your priority is putting more people on the water — it handles 8 passengers and at 17,0 ft it has the deck room to back that rating up comfortably. The Larson Cabrio 370 2004 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
