The Triton Boats TR-165 2006 vs Triton Boats TR-18 SE 2010 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 TR-165 2006 at 16,0 ft versus Triton Boats TR-18 SE 2010 at 18,5 ft. Weight tells a clearer story for trailering families: the Triton Boats TR-165 2006 tips the scales at 125 lbs — 112 lbs more than the Triton Boats TR-18 SE 2010 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 90 hp, the Triton Boats TR-165 2006 has a 75-hp advantage over the Triton Boats TR-18 SE 2010's 15-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 TR-18 SE 2010 carries 36 gallons versus 26 gallons in the Triton Boats TR-165 2006. 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 TR-18 SE 2010 is rated for 550 passengers, while the Triton Boats TR-165 2006 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Triton Boats TR-18 SE 2010 could be the deciding factor.
Bottom line: Choose the Triton Boats TR-18 SE 2010 if your priority is putting more people on the water — it handles 550 passengers and at 18,5 ft it has the deck room to back that rating up comfortably. The Triton Boats TR-165 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
