The Triton Boats DV 186 DC Mag 2006 vs Triton Boats TR-21X PD 2005 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 DV 186 DC Mag 2006 at 18,0 ft versus Triton Boats TR-21X PD 2005 at 21,0 ft. At 165 lbs and 175 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 250 hp, the Triton Boats TR-21X PD 2005 has a 50-hp advantage over the Triton Boats DV 186 DC Mag 2006's 200-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-21X PD 2005 carries 54 gallons versus 4 gallons in the Triton Boats DV 186 DC Mag 2006. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Bottom line: The Triton Boats TR-21X PD 2005 at 21,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Triton Boats DV 186 DC Mag 2006 at 18,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
