The Crestliner CMV 1850 2005 vs Crestliner CR 1648 MT 2007 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
On paper these two are close siblings in the size department — Crestliner CMV 1850 2005 at 18,0 ft versus Crestliner CR 1648 MT 2007 at 15,0 ft. Weight tells a clearer story for trailering families: the Crestliner CR 1648 MT 2007 tips the scales at 275 lbs — 262 lbs less than the Crestliner CMV 1850 2005 at 13 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 150 hp, the Crestliner CMV 1850 2005 has a 115-hp advantage over the Crestliner CR 1648 MT 2007'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 CMV 1850 2005 comes in at 0 lbs per hp versus 8 lbs per hp for the Crestliner CR 1648 MT 2007. 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: The Crestliner CMV 1850 2005 at 18,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Crestliner CR 1648 MT 2007 at 15,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
