Matching a flat Crestliner CR 1648 2012 against a modified vee Crestliner Super Hawk 1800 I/O 2008 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 CR 1648 2012 at 15,8 ft versus Crestliner Super Hawk 1800 I/O 2008 at 18,0 ft. Weight tells a clearer story for trailering families: the Crestliner Super Hawk 1800 I/O 2008 tips the scales at 2 105 lbs — 1 830 lbs less than the Crestliner CR 1648 2012 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 220 hp, the Crestliner Super Hawk 1800 I/O 2008 has a 185-hp advantage over the Crestliner CR 1648 2012'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 Super Hawk 1800 I/O 2008 is rated for 7 passengers, while the Crestliner CR 1648 2012 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner Super Hawk 1800 I/O 2008 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Crestliner CR 1648 2012 comes in at 8 lbs per hp versus 10 lbs per hp for the Crestliner Super Hawk 1800 I/O 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.
Bottom line: Choose the Crestliner Super Hawk 1800 I/O 2008 if your priority is putting more people on the water — it handles 7 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Crestliner CR 1648 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
