Larson 180 Sport 2009 vs Larson Cabrio 310 2005 - Boat Spec Comparison

Q: Which is easier to trailer — the Larson 180 Sport 2009 or the Larson Cabrio 310 2005?

For trailering, the Larson Cabrio 310 2005 has the edge at 104 lbs dry weight versus 2 375 lbs for the Larson 180 Sport 2009. 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: How many people can each boat hold?

The Larson 180 Sport 2009 is Coast Guard rated for 8 passengers, while the Larson Cabrio 310 2005 is certified for 9. 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 310 2005 measures 126" wide, compared to 88" for the Larson 180 Sport 2009. 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 180 Sport 2009 or the Larson Cabrio 310 2005?

The Larson 180 Sport 2009 has the bigger tank at 23 gallons, versus 16 gallons on the Larson Cabrio 310 2005. That 7-gallon difference translates to roughly 21–35 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Larson 180 Sport 2009 and Larson Cabrio 310 2005 from the same manufacturer?

Yes — both the Larson 180 Sport 2009 and the Larson Cabrio 310 2005 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 2009 vs Larson Cabrio 310 2005 — Same Brand, Different Boat

The Larson 180 Sport 2009 vs Larson Cabrio 310 2005 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.

For family outings this is probably the sharpest distinction between the two. The Larson Cabrio 310 2005 is rated for 9 passengers, while the Larson 180 Sport 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 2005 could be the deciding factor.

Bottom line: Choose the Larson Cabrio 310 2005 if your priority is putting more people on the water — it handles 9 passengers and at 0,0 ft it has the deck room to back that rating up comfortably. The Larson 180 Sport 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.
