The Triton Boats 1546 MRV 2005 vs Triton Boats 1870 Bay Sport 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 1546 MRV 2005 at 15,0 ft versus Triton Boats 1870 Bay Sport 2006 at 18,0 ft.

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 115 hp, the Triton Boats 1870 Bay Sport 2006 has a 85-hp advantage over the Triton Boats 1546 MRV 2005's 30-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
