Matching a modified vee Triton Boats 21XS 2013 against a deep vee Triton Boats DV 18 Magnum 2009 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 21XS 2013 measures 21,6 feet overall (2013), giving it roughly 3,6 additional feet of deck space compared to the Triton Boats DV 18 Magnum 2009 at 18,0 feet (2009). Weight tells a clearer story for trailering families: the Triton Boats 21XS 2013 tips the scales at 2 002 lbs — 1 877 lbs more than the Triton Boats DV 18 Magnum 2009 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 200 hp, the Triton Boats 21XS 2013 has a 50-hp advantage over the Triton Boats DV 18 Magnum 2009'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 21XS 2013 carries 46 gallons versus 31 gallons in the Triton Boats DV 18 Magnum 2009. 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 21XS 2013 is rated for 675 passengers, while the Triton Boats DV 18 Magnum 2009 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Triton Boats 21XS 2013 could be the deciding factor.
Bottom line: Choose the Triton Boats 21XS 2013 if your priority is putting more people on the water — it handles 675 passengers and at 21,6 ft it has the deck room to back that rating up comfortably. The Triton Boats DV 18 Magnum 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
