The Larson 180 Sport I/O 2008 is a modified-V design and the Larson Cabrio 857 2011 is a deep-V design, so you're likely deciding between two noticeably 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 857 2011 measures 28,2 feet overall (2011), giving it roughly 11,2 additional feet of deck space compared to the Larson 180 Sport I/O 2008 at 17,0 feet (2008). Weight tells a clearer story for trailering families: the Larson Cabrio 857 2011 tips the scales at 6 650 lbs - 4 275 lbs less than the Larson 180 Sport I/O 2008 at 2 375 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 400 hp, the Larson Cabrio 857 2011 has a 210-hp advantage over the Larson 180 Sport I/O 2008'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 857 2011 carries 84 gallons versus 23 gallons in the Larson 180 Sport I/O 2008. 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.
