When two boats share the same hull type — in this case both the Triton Boats 351 CC 2007 and the Triton Boats TS-17 2012 are modified vee designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

Size is the most obvious dividing line here. The Triton Boats 351 CC 2007 measures 34,0 feet overall (2007), giving it roughly 16,8 additional feet of deck space compared to the Triton Boats TS-17 2012 at 17,2 feet (2012). Weight tells a clearer story for trailering families: the Triton Boats 351 CC 2007 tips the scales at 8 532 lbs — 8 433 lbs more than the Triton Boats TS-17 2012 at 99 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 CC 2007 has a 850-hp advantage over the Triton Boats TS-17 2012's 50-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Triton Boats 351 CC 2007 carries 355 gallons versus 19 gallons in the Triton Boats TS-17 2012. 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 Triton Boats 351 CC 2007 is rated for 12 passengers, while the Triton Boats TS-17 2012 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 CC 2007 could be the deciding factor.
