Both the Crestliner C 1756 VS 2006 and the Crestliner Retriever 1650 SC 2013 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 C 1756 VS 2006 at 17,0 ft versus Crestliner Retriever 1650 SC 2013 at 16,0 ft. Weight tells a clearer story for trailering families: the Crestliner Retriever 1650 SC 2013 tips the scales at 700 lbs - 280 lbs less than the Crestliner C 1756 VS 2006 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.
Both boats share a closely matched power ceiling - 80 hp for the Crestliner C 1756 VS 2006 and 60 hp for the Crestliner Retriever 1650 SC 2013. 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 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 5 lbs per hp versus 12 lbs per hp for the Crestliner Retriever 1650 SC 2013. 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 Retriever 1650 SC 2013 with its 60-hp rating is the more economical daily driver.
