When two boats share the same hull type — in this case both the Triton Boats 170 CC 2007 and the Triton Boats 19XS 2012 are modified vee designs with aluminum 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?
On paper these two are close siblings in the size department — Triton Boats 170 CC 2007 at 17,0 ft versus Triton Boats 19XS 2012 at 19,8 ft. Weight tells a clearer story for trailering families: the Triton Boats 19XS 2012 tips the scales at 1 844 lbs — 1 755 lbs less than the Triton Boats 170 CC 2007 at 89 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 175 hp, the Triton Boats 19XS 2012 has a 85-hp advantage over the Triton Boats 170 CC 2007's 90-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 19XS 2012 is rated for 650 passengers, while the Triton Boats 170 CC 2007 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 19XS 2012 could be the deciding factor.
Bottom line: Choose the Triton Boats 19XS 2012 if your priority is putting more people on the water — it handles 650 passengers and at 19,8 ft it has the deck room to back that rating up comfortably. The Triton Boats 170 CC 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
