The Larson 186 Senza 2010 is a modified-V design and the Larson FX 2050 TL O/B 2013 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.

On paper these two are close siblings in the size department - Larson 186 Senza 2010 at 18,5 ft versus Larson FX 2050 TL O/B 2013 at 20,2 ft. Weight tells a clearer story for trailering families: the Larson 186 Senza 2010 tips the scales at 2 700 lbs - 121 lbs more than the Larson FX 2050 TL O/B 2013 at 2 579 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 270 hp, the Larson 186 Senza 2010 has a 70-hp advantage over the Larson FX 2050 TL O/B 2013's 200-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 FX 2050 TL O/B 2013 carries 35 gallons versus 29 gallons in the Larson 186 Senza 2010. 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 186 Senza 2010 is rated for 9 passengers, while the Larson FX 2050 TL O/B 2013 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Larson 186 Senza 2010 could be the deciding factor.
