The Triton Boats 1648 SFB 2010 is a flat-bottom design and the Triton Boats 351 Express 2007 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 351 Express 2007 measures 34,0 feet overall (2007), giving it roughly 18,2 additional feet of deck space compared to the Triton Boats 1648 SFB 2010 at 15,8 feet (2010). Weight tells a clearer story for trailering families: the Triton Boats 351 Express 2007 tips the scales at 9 432 lbs - 9 012 lbs less than the Triton Boats 1648 SFB 2010 at 420 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 900 hp, the Triton Boats 351 Express 2007 has a 865-hp advantage over the Triton Boats 1648 SFB 2010's 35-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 351 Express 2007 is rated for 12 passengers, while the Triton Boats 1648 SFB 2010 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Triton Boats 351 Express 2007 could be the deciding factor.
