Matching a modified vee Crestliner Canadian 1850 2010 against a flat Crestliner CR 1648M 2012 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 Canadian 1850 2010 at 18,2 ft versus Crestliner CR 1648M 2012 at 15,8 ft. Weight tells a clearer story for trailering families: the Crestliner CR 1648M 2012 tips the scales at 275 lbs — 260 lbs less than the Crestliner Canadian 1850 2010 at 15 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.
