When two boats share the same hull type — in this case both the Crestliner CR 1648 M 2008 and the Crestliner CX 17 Bass 2008 are modified vee designs with aluminum construction — 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 CR 1648 M 2008 at 15,0 ft versus Crestliner CX 17 Bass 2008 at 17,0 ft. Weight tells a clearer story for trailering families: the Crestliner CR 1648 M 2008 tips the scales at 275 lbs — 171 lbs more than the Crestliner CX 17 Bass 2008 at 104 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 90 hp, the Crestliner CX 17 Bass 2008 has a 55-hp advantage over the Crestliner CR 1648 M 2008'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 CX 17 Bass 2008 comes in at 1 lbs per hp versus 8 lbs per hp for the Crestliner CR 1648 M 2008. 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.
