Detailed Evaluation & Buyer Recommendation
Larson FX 1850 DC O/B 2013 vs Larson Senza 186 2009: Same Brand, Different Boat
The Larson FX 1850 DC O/B 2013 is a deep-V design and the Larson Senza 186 2009 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.
On paper these two are close siblings in the size department - Larson FX 1850 DC O/B 2013 at 18,5 ft versus Larson Senza 186 2009 at 18,0 ft. Weight tells a clearer story for trailering families: the Larson Senza 186 2009 tips the scales at 2 700 lbs - 481 lbs less than the Larson FX 1850 DC O/B 2013 at 2 219 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 FX 1850 DC O/B 2013 carries a rated maximum of 175 hp. Engine data for the Larson Senza 186 2009 wasn't available in our records - check the manufacturer's spec sheet before sizing a motor.Both carry nearly identical fuel loads - 30 gal and 29 gal - so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Larson Senza 186 2009 is rated for 9 passengers, while the Larson FX 1850 DC 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 Senza 186 2009 could be the deciding factor.
Bottom line: Choose the Larson Senza 186 2009 if your priority is putting more people on the water - it handles 9 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Larson FX 1850 DC O/B 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
