Matching a flat Triton Boats 1648 SFB 2008 against a modified vee Triton Boats TS-18 2007 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 — Triton Boats 1648 SFB 2008 at 15,0 ft versus Triton Boats TS-18 2007 at 18,0 ft. Weight tells a clearer story for trailering families: the Triton Boats 1648 SFB 2008 tips the scales at 275 lbs — 169 lbs more than the Triton Boats TS-18 2007 at 106 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 2007 has a 80-hp advantage over the Triton Boats 1648 SFB 2008's 35-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
Both boats are rated for 4 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.
At this size, power-to-weight ratio matters more than outright horsepower. The Triton Boats TS-18 2007 comes in at 1 lbs per hp versus 8 lbs per hp for the Triton Boats 1648 SFB 2008.

The Triton Boats 1648 SFB 2008 at 15,0 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.
