Both the Crestliner Ambush 18 2011 and the Crestliner Backwater 1760 SC 2011 are modified-V designs, both built in aluminium, 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?

On paper these two are close siblings in the size department - Crestliner Ambush 18 2011 at 18,0 ft versus Crestliner Backwater 1760 SC 2011 at 17,3 ft. Weight tells a clearer story for trailering families: the Crestliner Ambush 18 2011 tips the scales at 1 009 lbs - 220 lbs more than the Crestliner Backwater 1760 SC 2011 at 789 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 - 90 hp for the Crestliner Ambush 18 2011 and 75 hp for the Crestliner Backwater 1760 SC 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. Both carry nearly identical fuel loads - 22 gal and 20 gal - so range won't be a tiebreaker here.

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 Crestliner Backwater 1760 SC 2011 comes in at 11 lbs per hp versus 11 lbs per hp for the Crestliner 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.
