Both the Crestliner Sportsman 18 SS SC 2007 and the Crestliner Super Hawk 1800 I/O 2008 are modified-V designs, so 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 Sportsman 18 SS SC 2007 at 18,0 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 - 1 435 lbs less than the Crestliner Sportsman 18 SS SC 2007 at 670 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 170-hp advantage over the Crestliner Sportsman 18 SS SC 2007's 50-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
Both boats are rated for 7 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 Super Hawk 1800 I/O 2008 comes in at 10 lbs per hp versus 13 lbs per hp for the Crestliner Sportsman 18 SS SC 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: Performance buyers should lean toward the Crestliner Super Hawk 1800 I/O 2008 and its 220-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Crestliner Sportsman 18 SS SC 2007 with its 50-hp rating is the more economical daily driver.
