The Triton Boats 170CC 2005 vs Triton Boats TR-21XD DC 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.
Size is the most obvious dividing line here. The Triton Boats TR-21XD DC 2006 measures 21,0 feet overall (2006), giving it roughly 4,0 additional feet of deck space compared to the Triton Boats 170CC 2005 at 17,0 feet (2005). Weight tells a clearer story for trailering families: the Triton Boats TR-21XD DC 2006 tips the scales at 195 lbs — 187 lbs less than the Triton Boats 170CC 2005 at 8 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 250 hp, the Triton Boats TR-21XD DC 2006 has a 160-hp advantage over the Triton Boats 170CC 2005's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Triton Boats TR-21XD DC 2006 is rated for 6 passengers, while the Triton Boats 170CC 2005 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 TR-21XD DC 2006 could be the deciding factor.
Bottom line: Choose the Triton Boats TR-21XD DC 2006 if your priority is putting more people on the water — it handles 6 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Triton Boats 170CC 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
