Larson 180 Sport I/O 2007 vs Larson Cabrio 240 2011 — Same Brand, Different Boat

Matching a modified vee Larson 180 Sport I/O 2007 against a deep vee Larson Cabrio 240 2011 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

Size is the most obvious dividing line here. The Larson Cabrio 240 2011 measures 24,6 feet overall (2011), giving it roughly 7,6 additional feet of deck space compared to the Larson 180 Sport I/O 2007 at 17,0 feet (2007). Weight tells a clearer story for trailering families: the Larson 180 Sport I/O 2007 tips the scales at 2 375 lbs — 1 800 lbs more than the Larson Cabrio 240 2011 at 575 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The power gap is worth calling out. Rated to 320 hp, the Larson Cabrio 240 2011 has a 130-hp advantage over the Larson 180 Sport I/O 2007's 190-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 240 2011 carries 84 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.

Both boats are rated for 8 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: The Larson Cabrio 240 2011 at 24,6 ft is the right call if deck space, comfort, and entertaining are top of your list. The Larson 180 Sport I/O 2007 at 17,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.

Larson 180 Sport I/O 2007 vs Larson Cabrio 240 2011 — Common Questions

Which is the larger boat — the Larson 180 Sport I/O 2007 or the Larson Cabrio 240 2011?
The Larson Cabrio 240 2011 is the longer of the two at 24,6 feet overall. The Larson 180 Sport I/O 2007 comes in at 17,0 feet, making it roughly 7,6 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Larson 180 Sport I/O 2007 or the Larson Cabrio 240 2011?
For trailering, the Larson Cabrio 240 2011 has the edge at 575 lbs dry weight versus 2 375 lbs for the Larson 180 Sport I/O 2007. 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.
Which boat can handle a bigger outboard?
The Larson Cabrio 240 2011 is rated to a maximum of 320 hp, giving it the larger power ceiling. The Larson 180 Sport I/O 2007 tops out at 190 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.
How many people can each boat hold?
The Larson 180 Sport I/O 2007 is Coast Guard rated for 8 passengers, while the Larson Cabrio 240 2011 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.
Which boat is wider, and does it affect trailering?
The Larson Cabrio 240 2011 measures 102" 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.
Which boat has the larger fuel tank — the Larson 180 Sport I/O 2007 or the Larson Cabrio 240 2011?
The Larson Cabrio 240 2011 has the bigger tank at 84 gallons, versus 23 gallons on the Larson 180 Sport I/O 2007. That 61-gallon difference translates to roughly 183–305 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Larson 180 Sport I/O 2007 and Larson Cabrio 240 2011 from the same manufacturer?
Yes — both the Larson 180 Sport I/O 2007 and the Larson Cabrio 240 2011 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.
