Both the Crestliner Backwater 1860 SC 2011 and the Crestliner C 1760 V 2008 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 Backwater 1860 SC 2011 at 18,4 ft versus Crestliner C 1760 V 2008 at 17,0 ft. At 880 lbs and 950 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 115 hp, the Crestliner Backwater 1860 SC 2011 has a 65-hp advantage over the Crestliner C 1760 V 2008's 50-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.
Bottom line: Performance buyers should lean toward the Crestliner Backwater 1860 SC 2011 and its 115-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Crestliner C 1760 V 2008 with its 50-hp rating is the more economical daily driver.
