The Triton Boats DV 16 2010 is a deep-V design and the Triton Boats Tr-18 2010 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 DV 16 2010 at 16,3 ft versus Triton Boats Tr-18 2010 at 18,5 ft. Weight tells a clearer story for trailering families: the Triton Boats Tr-18 2010 tips the scales at 1 300 lbs - 300 lbs less than the Triton Boats DV 16 2010 at 1 000 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 - 90 hp for the Triton Boats DV 16 2010 and 90 hp for the Triton Boats Tr-18 2010. 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 Tr-18 2010 carries 36 gallons versus 17 gallons in the Triton Boats DV 16 2010. 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 Tr-18 2010 is rated for 550 passengers, while the Triton Boats DV 16 2010 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Triton Boats Tr-18 2010 could be the deciding factor.
Bottom line: Choose the Triton Boats Tr-18 2010 if your priority is putting more people on the water - it handles 550 passengers and at 18,5 ft it has the deck room to back that rating up comfortably. The Triton Boats DV 16 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
