When two boats share the same hull type — in this case both the Triton Boats 1756 DS 2009 and the Triton Boats 220 LTS Pro 2011 are modified vee designs with aluminum construction — 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?
Size is the most obvious dividing line here. The Triton Boats 220 LTS Pro 2011 measures 22,0 feet overall (2011), giving it roughly 5,0 additional feet of deck space compared to the Triton Boats 1756 DS 2009 at 17,0 feet (2009). Weight tells a clearer story for trailering families: the Triton Boats 1756 DS 2009 tips the scales at 605 lbs — 582 lbs more than the Triton Boats 220 LTS Pro 2011 at 23 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 150 hp, the Triton Boats 220 LTS Pro 2011 has a 90-hp advantage over the Triton Boats 1756 DS 2009's 60-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 220 LTS Pro 2011 is rated for 7 passengers, while the Triton Boats 1756 DS 2009 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 220 LTS Pro 2011 could be the deciding factor.
Bottom line: Choose the Triton Boats 220 LTS Pro 2011 if your priority is putting more people on the water — it handles 7 passengers and at 22,0 ft it has the deck room to back that rating up comfortably. The Triton Boats 1756 DS 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
