When two boats share the same hull type — in this case both the Crestliner Backwater Series 1655 Tiller 2009 and the Crestliner C 1870 V 2008 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 Series 1655 Tiller 2009 at 16,0 ft versus Crestliner C 1870 V 2008 at 18,0 ft. Weight tells a clearer story for trailering families: the Crestliner C 1870 V 2008 tips the scales at 1 125 lbs — 300 lbs less than the Crestliner Backwater Series 1655 Tiller 2009 at 825 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 — 50 hp for the Crestliner Backwater Series 1655 Tiller 2009 and 60 hp for the Crestliner C 1870 V 2008. 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 C 1870 V 2008 is rated for 5 passengers, while the Crestliner Backwater Series 1655 Tiller 2009 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner C 1870 V 2008 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Crestliner Backwater Series 1655 Tiller 2009 comes in at 17 lbs per hp versus 19 lbs per hp for the Crestliner C 1870 V 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.
