The Crestliner Ambush 16 2011 is a modified-V design and the Crestliner CR 1648MT 2010 is a flat-bottom design, so you're likely deciding between two noticeably 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 - Crestliner Ambush 16 2011 at 16,0 ft versus Crestliner CR 1648MT 2010 at 15,8 ft. Weight tells a clearer story for trailering families: the Crestliner Ambush 16 2011 tips the scales at 900 lbs - 480 lbs more than the Crestliner CR 1648MT 2010 at 420 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 60 hp, the Crestliner Ambush 16 2011 has a 25-hp advantage over the Crestliner CR 1648MT 2010's 35-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 CR 1648MT 2010 comes in at 12 lbs per hp versus 15 lbs per hp for the Crestliner Ambush 16 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 Crestliner Ambush 16 2011 and its 60-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Crestliner CR 1648MT 2010 with its 35-hp rating is the more economical daily driver.
