The Triton Boats A1436 SFB 2011 is a flat-bottom design and the Triton Boats TS-18 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.
Size is the most obvious dividing line here. The Triton Boats TS-18 2009 measures 18,0 feet overall (2009), giving it roughly 4,0 additional feet of deck space compared to the Triton Boats A1436 SFB 2011 at 14,0 feet (2011). Weight tells a clearer story for trailering families: the Triton Boats TS-18 2009 tips the scales at 1 060 lbs - 915 lbs less than the Triton Boats A1436 SFB 2011 at 145 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 115 hp, the Triton Boats TS-18 2009 has a 95-hp advantage over the Triton Boats A1436 SFB 2011's 20-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Triton Boats TS-18 2009 is rated for 4 passengers, while the Triton Boats A1436 SFB 2011 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Triton Boats TS-18 2009 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Triton Boats A1436 SFB 2011 comes in at 7 lbs per hp versus 9 lbs per hp for the Triton Boats TS-18 2009. The lower the ratio the more explosive the acceleration - meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
Bottom line: Choose the Triton Boats TS-18 2009 if your priority is putting more people on the water - it handles 4 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Triton Boats A1436 SFB 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 3 that costs less to run day-to-day.
