The Triton Boats 173 Sport 2006 vs Triton Boats 191 LTS 2006 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 173 Sport 2006 at 17,0 ft versus Triton Boats 191 LTS 2006 at 19,0 ft.

The power gap is worth calling out. Rated to 150 hp, the Triton Boats 191 LTS 2006 has a 70-hp advantage over the Triton Boats 173 Sport 2006's 80-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
