Both the Crestliner Ambush 18 2011 and the Crestliner C 1760 VCC 2007 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 C 1760 VCC 2007 at 17,0 ft. At 1 009 lbs and 975 lbs respectively, both sit in a similar weight class - either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 90 hp, the Crestliner Ambush 18 2011 has a 30-hp advantage over the Crestliner C 1760 VCC 2007's 60-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 Crestliner Ambush 18 2011 comes in at 11 lbs per hp versus 16 lbs per hp for the Crestliner C 1760 VCC 2007. 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 Crestliner Ambush 18 2011 and its 90-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Crestliner C 1760 VCC 2007 with its 60-hp rating is the more economical daily driver.
