When two boats share the same hull type — in this case both the Triton Boats Ambush 18 2011 and the Triton Boats DV 150 2007 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 Ambush 18 2011 measures 18,0 feet overall (2011), giving it roughly 4,0 additional feet of deck space compared to the Triton Boats DV 150 2007 at 14,0 feet (2007). Weight tells a clearer story for trailering families: the Triton Boats Ambush 18 2011 tips the scales at 958 lbs — 896 lbs more than the Triton Boats DV 150 2007 at 62 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 DV 150 2007's 40-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 DV 150 2007 is rated for 5 passengers, while the Triton Boats Ambush 18 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 DV 150 2007 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Triton Boats DV 150 2007 comes in at 2 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.
