Matching a deep vee Larson LX 180 S O/B 2013 against a modified vee Larson Senza 226 I/O 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 Senza 226 I/O 2011 measures 22,3 feet overall (2011), giving it roughly 3,8 additional feet of deck space compared to the Larson LX 180 S O/B 2013 at 18,5 feet (2013). Weight tells a clearer story for trailering families: the Larson LX 180 S O/B 2013 tips the scales at 2 179 lbs — 1 794 lbs more than the Larson Senza 226 I/O 2011 at 385 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 300 hp, the Larson Senza 226 I/O 2011 has a 150-hp advantage over the Larson LX 180 S O/B 2013's 150-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 Senza 226 I/O 2011 carries 56 gallons versus 3 gallons in the Larson LX 180 S O/B 2013. 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 Senza 226 I/O 2011 is rated for 11 passengers, while the Larson LX 180 S O/B 2013 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Larson Senza 226 I/O 2011 could be the deciding factor.
Bottom line: Choose the Larson Senza 226 I/O 2011 if your priority is putting more people on the water — it handles 11 passengers and at 22,3 ft it has the deck room to back that rating up comfortably. The Larson LX 180 S O/B 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
