When two boats share the same hull type — in this case both the Crestliner Backwater Series 1870 SC 2009 and the Crestliner Retriever Jon Deluxe 1756 2012 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 1870 SC 2009 at 18,0 ft versus Crestliner Retriever Jon Deluxe 1756 2012 at 16,8 ft. Weight tells a clearer story for trailering families: the Crestliner Backwater Series 1870 SC 2009 tips the scales at 1 175 lbs — 1 111 lbs more than the Crestliner Retriever Jon Deluxe 1756 2012 at 64 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 90 hp, the Crestliner Backwater Series 1870 SC 2009 has a 30-hp advantage over the Crestliner Retriever Jon Deluxe 1756 2012's 60-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

Both boats are rated for 5 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 Retriever Jon Deluxe 1756 2012 comes in at 1 lbs per hp versus 13 lbs per hp for the Crestliner Backwater Series 1870 SC 2009. 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.
