Matching a modified vee Crestliner C 1756 VS 2006 against a flat Crestliner CR 1648MT 2010 means you're likely deciding between two genuinely 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 C 1756 VS 2006 at 17,0 ft versus Crestliner CR 1648MT 2010 at 15,8 ft. At 42 lbs and 42 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 80 hp, the Crestliner C 1756 VS 2006 has a 45-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 C 1756 VS 2006 comes in at 1 lbs per hp versus 1 lbs per hp for the Crestliner CR 1648MT 2010. 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 C 1756 VS 2006 and its 80-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.
