The Triton Boats 191LTS 2005 vs Triton Boats DV 17 Liberty 2009 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
On paper these two are close siblings in the size department — Triton Boats 191LTS 2005 at 19,0 ft versus Triton Boats DV 17 Liberty 2009 at 17,0 ft. Weight tells a clearer story for trailering families: the Triton Boats 191LTS 2005 tips the scales at 165 lbs — 152 lbs more than the Triton Boats DV 17 Liberty 2009 at 13 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 150 hp, the Triton Boats 191LTS 2005 has a 25-hp advantage over the Triton Boats DV 17 Liberty 2009's 125-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 191LTS 2005 carries 55 gallons versus 33 gallons in the Triton Boats DV 17 Liberty 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Triton Boats DV 17 Liberty 2009 could be the deciding factor.
Bottom line: Choose the Triton Boats DV 17 Liberty 2009 if your priority is putting more people on the water — it handles 6 passengers and at 17,0 ft it has the deck room to back that rating up comfortably. The Triton Boats 191LTS 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
