Both the Triton Boats 1650 DS 2011 and the Triton Boats TR200 2008 are modified-V designs, the first built in aluminium and the second in fibreglass, so the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
The power gap is worth calling out. Rated to 225 hp, the Triton Boats TR200 2008 has a 200-hp advantage over the Triton Boats 1650 DS 2011's 25-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Triton Boats TR200 2008 is rated for 645 passengers, while the Triton Boats 1650 DS 2011 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Triton Boats TR200 2008 could be the deciding factor.
Bottom line: Choose the Triton Boats TR200 2008 if your priority is putting more people on the water - it handles 645 passengers and at 20,0 ft it has the deck room to back that rating up comfortably. The Triton Boats 1650 DS 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
