Detailed Evaluation & Buyer Recommendation
Larson FX 1850 DC O/B 2013 vs Larson Senza 186 I/O 2008 — Same Brand, Different Boat
Matching a deep vee Larson FX 1850 DC O/B 2013 against a modified vee Larson Senza 186 I/O 2008 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.
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 I/O 2008 at 18,0 ft. Weight tells a clearer story for trailering families: the Larson FX 1850 DC O/B 2013 tips the scales at 2 219 lbs — 2 192 lbs more than the Larson Senza 186 I/O 2008 at 27 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 225 hp, the Larson Senza 186 I/O 2008 has a 50-hp advantage over the Larson FX 1850 DC O/B 2013's 175-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 186 I/O 2008 carries 29 gallons versus 3 gallons in the Larson FX 1850 DC 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 186 I/O 2008 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 I/O 2008 could be the deciding factor.
Bottom line: Choose the Larson Senza 186 I/O 2008 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.
