When two boats share the same hull type — in this case both the Crestliner Backwater 1870 SC/CC 2010 and the Crestliner Super Hawk 1600 2011 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 Backwater 1870 SC/CC 2010 at 18,0 ft versus Crestliner Super Hawk 1600 2011 at 16,3 ft. Weight tells a clearer story for trailering families: the Crestliner Backwater 1870 SC/CC 2010 tips the scales at 1 175 lbs — 1 174 lbs more than the Crestliner Super Hawk 1600 2011 at 1 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 Backwater 1870 SC/CC 2010 and 90 hp for the Crestliner Super Hawk 1600 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.

For family outings this is probably the sharpest distinction between the two. The Crestliner Super Hawk 1600 2011 is rated for 6 passengers, while the Crestliner Backwater 1870 SC/CC 2010 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner Super Hawk 1600 2011 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Crestliner Super Hawk 1600 2011 comes in at 0 lbs per hp versus 13 lbs per hp for the Crestliner Backwater 1870 SC/CC 2010. 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.
