Both the Crestliner CXJ 1870 SC 2008 and the Crestliner Fish Hawk 1650 SC 2011 are modified-V designs, both built in aluminium, 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 CXJ 1870 SC 2008 at 18,0 ft versus Crestliner Fish Hawk 1650 SC 2011 at 16,7 ft. Weight tells a clearer story for trailering families: the Crestliner CXJ 1870 SC 2008 tips the scales at 1 175 lbs - 115 lbs more than the Crestliner Fish Hawk 1650 SC 2011 at 1 060 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.

Both boats share a closely matched power ceiling - 90 hp for the Crestliner CXJ 1870 SC 2008 and 90 hp for the Crestliner Fish Hawk 1650 SC 2011. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads - 21 gal and 20 gal - so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Crestliner Fish Hawk 1650 SC 2011 is rated for 6 passengers, while the Crestliner CXJ 1870 SC 2008 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner Fish Hawk 1650 SC 2011 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Crestliner Fish Hawk 1650 SC 2011 comes in at 12 lbs per hp versus 13 lbs per hp for the Crestliner CXJ 1870 SC 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.
