The Crestliner Canadian Series 1650 2009 is a modified-V design and the Crestliner CR 1648M/MT 2011 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 Canadian Series 1650 2009 at 16,0 ft versus Crestliner CR 1648M/MT 2011 at 15,8 ft. Weight tells a clearer story for trailering families: the Crestliner Canadian Series 1650 2009 tips the scales at 1 000 lbs - 725 lbs more than the Crestliner CR 1648M/MT 2011 at 275 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 115 hp, the Crestliner Canadian Series 1650 2009 has a 80-hp advantage over the Crestliner CR 1648M/MT 2011's 35-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Crestliner Canadian Series 1650 2009 is rated for 5 passengers, while the Crestliner CR 1648M/MT 2011 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner Canadian Series 1650 2009 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Crestliner CR 1648M/MT 2011 comes in at 8 lbs per hp versus 9 lbs per hp for the Crestliner Canadian Series 1650 2009. 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.
