When two boats share the same hull type — in this case both the Triton Boats 170 DS SC 2009 and the Triton Boats VT 19 2008 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 DS SC 2009 at 17,0 ft versus Triton Boats VT 19 2008 at 19,0 ft. Weight tells a clearer story for trailering families: the Triton Boats 170 DS SC 2009 tips the scales at 925 lbs — 914 lbs more than the Triton Boats VT 19 2008 at 11 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 135 hp, the Triton Boats VT 19 2008 has a 60-hp advantage over the Triton Boats 170 DS SC 2009's 75-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.
Bottom line: Performance buyers should lean toward the Triton Boats VT 19 2008 and its 135-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Triton Boats 170 DS SC 2009 with its 75-hp rating is the more economical daily driver.
