The Triton Boats 191LTS 2005 vs Triton Boats TS-17 2008 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 TS-17 2008 at 17,0 ft. At 165 lbs and 99 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 150 hp, the Triton Boats 191LTS 2005 has a 60-hp advantage over the Triton Boats TS-17 2008's 90-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 19 gallons in the Triton Boats TS-17 2008. 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 191LTS 2005 is rated for 5 passengers, while the Triton Boats TS-17 2008 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 191LTS 2005 could be the deciding factor.
Bottom line: Choose the Triton Boats 191LTS 2005 if your priority is putting more people on the water — it handles 5 passengers and at 19,0 ft it has the deck room to back that rating up comfortably. The Triton Boats TS-17 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
