The Triton Boats 215 DC 2011 is a deep-V design and the Triton Boats 21HP 2013 is a modified-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
On paper these two are close siblings in the size department - Triton Boats 215 DC 2011 at 21,4 ft versus Triton Boats 21HP 2013 at 21,0 ft. Weight tells a clearer story for trailering families: the Triton Boats 215 DC 2011 tips the scales at 2 300 lbs - 460 lbs more than the Triton Boats 21HP 2013 at 1 840 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.
Both boats share a closely matched power ceiling - 200 hp for the Triton Boats 215 DC 2011 and 200 hp for the Triton Boats 21HP 2013. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Triton Boats 215 DC 2011 carries 50 gallons versus 46 gallons in the Triton Boats 21HP 2013. 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 215 DC 2011 is rated for 950 passengers, while the Triton Boats 21HP 2013 caps at 675. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Triton Boats 215 DC 2011 could be the deciding factor.
Bottom line: Choose the Triton Boats 215 DC 2011 if your priority is putting more people on the water - it handles 950 passengers and at 21,4 ft it has the deck room to back that rating up comfortably. The Triton Boats 21HP 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 675 that costs less to run day-to-day.
