Triton Boats 1650 DS 2007 vs Triton Boats Ambush 18 2011 — Same Brand, Different Boat

The Triton Boats 1650 DS 2007 vs Triton Boats Ambush 18 2011 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

On paper these two are close siblings in the size department — Triton Boats 1650 DS 2007 at 16,0 ft versus Triton Boats Ambush 18 2011 at 18,0 ft. Weight tells a clearer story for trailering families: the Triton Boats Ambush 18 2011 tips the scales at 958 lbs — 901 lbs less than the Triton Boats 1650 DS 2007 at 57 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 75 hp, the Triton Boats Ambush 18 2011 has a 35-hp advantage over the Triton Boats 1650 DS 2007's 40-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

Both boats are rated for 4 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

At this size, power-to-weight ratio matters more than outright horsepower. The Triton Boats 1650 DS 2007 comes in at 1 lbs per hp versus 13 lbs per hp for the Triton Boats Ambush 18 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: Performance buyers should lean toward the Triton Boats Ambush 18 2011 and its 75-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Triton Boats 1650 DS 2007 with its 40-hp rating is the more economical daily driver.

Triton Boats 1650 DS 2007 vs Triton Boats Ambush 18 2011 — Common Questions

Which is the larger boat — the Triton Boats 1650 DS 2007 or the Triton Boats Ambush 18 2011?
The Triton Boats Ambush 18 2011 is the longer of the two at 18,0 feet overall. The Triton Boats 1650 DS 2007 comes in at 16,0 feet, making it roughly 2,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Triton Boats 1650 DS 2007 or the Triton Boats Ambush 18 2011?
For trailering, the Triton Boats 1650 DS 2007 has the edge at 57 lbs dry weight versus 958 lbs for the Triton Boats Ambush 18 2011. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Triton Boats Ambush 18 2011 is rated to a maximum of 75 hp, giving it the larger power ceiling. The Triton Boats 1650 DS 2007 tops out at 40 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Triton Boats 1650 DS 2007 is Coast Guard rated for 4 passengers, while the Triton Boats Ambush 18 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 1650 DS 2007 has a better power-to-weight ratio at 1 lbs per hp compared to 13 lbs per hp for the Triton Boats Ambush 18 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 Ambush 18 2011 measures 79" wide, compared to 74" for the Triton Boats 1650 DS 2007. 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.
Are the Triton Boats 1650 DS 2007 and Triton Boats Ambush 18 2011 from the same manufacturer?
Yes — both the Triton Boats 1650 DS 2007 and the Triton Boats Ambush 18 2011 are built by Triton Boats. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
