Larson Cabrio 350 2007 vs Larson SEi 180 Sport 2005 - Boat Spec Comparison

Q: Which is easier to trailer — the Larson Cabrio 350 2007 or the Larson SEi 180 Sport 2005?

For trailering, the Larson Cabrio 350 2007 has the edge at 14 lbs dry weight versus 2 365 lbs for the Larson SEi 180 Sport 2005. 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: What is the maximum horsepower rating for these boats?

The Larson Cabrio 350 2007 has a documented max rating of 350 hp. Engine specifications for the Larson SEi 180 Sport 2005 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 350 2007 is Coast Guard rated for 11 passengers, while the Larson SEi 180 Sport 2005 is certified for 8. 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 350 2007 measures 144" wide, compared to 93" for the Larson SEi 180 Sport 2005. 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: How do the fuel tanks compare on the Larson Cabrio 350 2007 and Larson SEi 180 Sport 2005?

Both boats carry similar fuel loads — 23 gallons and 23 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.

Q: Are the Larson Cabrio 350 2007 and Larson SEi 180 Sport 2005 from the same manufacturer?

Yes — both the Larson Cabrio 350 2007 and the Larson SEi 180 Sport 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.
