The Larson LX 160 O/B 2013 is a deep-V design and the Larson Senza™ 186 Super Sport I/O 2006 is a modified-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 Senza™ 186 Super Sport I/O 2006 measures 20,0 feet overall (2006), giving it roughly 3,8 additional feet of deck space compared to the Larson LX 160 O/B 2013 at 16,2 feet (2013). Weight tells a clearer story for trailering families: the Larson Senza™ 186 Super Sport I/O 2006 tips the scales at 2 850 lbs - 1 301 lbs less than the Larson LX 160 O/B 2013 at 1 549 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 Larson LX 160 O/B 2013 carries a rated maximum of 90 hp. Engine data for the Larson Senza™ 186 Super Sport I/O 2006 wasn't available in our records - check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Larson Senza™ 186 Super Sport I/O 2006 carries 29 gallons versus 19 gallons in the Larson LX 160 O/B 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 6 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 Senza™ 186 Super Sport I/O 2006 at 20,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Larson LX 160 O/B 2013 at 16,2 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.
