Triton Boats 1756 DS 2011 vs Triton Boats A1648 SFB 2011 — Same Brand, Different Boat

Matching a modified vee Triton Boats 1756 DS 2011 against a flat Triton Boats A1648 SFB 2011 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.

On paper these two are close siblings in the size department — Triton Boats 1756 DS 2011 at 17,0 ft versus Triton Boats A1648 SFB 2011 at 15,8 ft. Weight tells a clearer story for trailering families: the Triton Boats 1756 DS 2011 tips the scales at 605 lbs — 330 lbs more than the Triton Boats A1648 SFB 2011 at 275 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 — 40 hp for the Triton Boats 1756 DS 2011 and 35 hp for the Triton Boats A1648 SFB 2011. 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.

For family outings this is probably the sharpest distinction between the two. The Triton Boats 1756 DS 2011 is rated for 5 passengers, while the Triton Boats A1648 SFB 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 1756 DS 2011 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Triton Boats A1648 SFB 2011 comes in at 8 lbs per hp versus 15 lbs per hp for the Triton Boats 1756 DS 2011. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.

Bottom line: Choose the Triton Boats 1756 DS 2011 if your priority is putting more people on the water — it handles 5 passengers and at 17,0 ft it has the deck room to back that rating up comfortably. The Triton Boats A1648 SFB 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.

Triton Boats 1756 DS 2011 vs Triton Boats A1648 SFB 2011 — Common Questions

Which is the larger boat — the Triton Boats 1756 DS 2011 or the Triton Boats A1648 SFB 2011?
The Triton Boats 1756 DS 2011 is the longer of the two at 17,0 feet overall. The Triton Boats A1648 SFB 2011 comes in at 15,8 feet, making it roughly 1,2 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Triton Boats 1756 DS 2011 or the Triton Boats A1648 SFB 2011?
For trailering, the Triton Boats A1648 SFB 2011 has the edge at 275 lbs dry weight versus 605 lbs for the Triton Boats 1756 DS 2011.

How many people can each boat hold?
The Triton Boats 1756 DS 2011 is Coast Guard rated for 5 passengers, while the Triton Boats A1648 SFB 2011 is certified for 4. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat has the better power-to-weight ratio?
The Triton Boats A1648 SFB 2011 has a better power-to-weight ratio at 8 lbs per hp compared to 15 lbs per hp for the Triton Boats 1756 DS 2011. A lower number means quicker acceleration and faster time to plane — the number that actually matters most on short, sporty boats like these.
Which boat is wider, and does it affect trailering?
The Triton Boats 1756 DS 2011 measures 8" wide, compared to 7" for the Triton Boats A1648 SFB 2011. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
