Matching a modified vee Triton Boats 20HP 2009 against a deep vee Triton Boats DV 18 Magnum 2010 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
Size is the most obvious dividing line here. The Triton Boats DV 18 Magnum 2010 measures 18,5 feet overall (2010), giving it roughly 16,5 additional feet of deck space compared to the Triton Boats 20HP 2009 at 2,0 feet (2009). Weight tells a clearer story for trailering families: the Triton Boats 20HP 2009 tips the scales at 1 764 lbs — 1 639 lbs more than the Triton Boats DV 18 Magnum 2010 at 125 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 20HP 2009 has a 100-hp advantage over the Triton Boats DV 18 Magnum 2010's 150-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 20HP 2009 carries 54 gallons versus 31 gallons in the Triton Boats DV 18 Magnum 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 6 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: The Triton Boats DV 18 Magnum 2010 at 18,5 ft is the right call if deck space, comfort, and entertaining are top of your list. The Triton Boats 20HP 2009 at 2,0 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.
