When two boats share the same hull type — in this case both the Crestliner C 1870 VS 2007 and the Crestliner Jons - CR 1852MT 2009 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 C 1870 VS 2007 at 18,0 ft versus Crestliner Jons - CR 1852MT 2009 at 18,0 ft. Weight tells a clearer story for trailering families: the Crestliner Jons - CR 1852MT 2009 tips the scales at 475 lbs — 360 lbs less than the Crestliner C 1870 VS 2007 at 115 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 75 hp, the Crestliner C 1870 VS 2007 has a 30-hp advantage over the Crestliner Jons - CR 1852MT 2009's 45-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Crestliner Jons - CR 1852MT 2009 is rated for 6 passengers, while the Crestliner C 1870 VS 2007 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner Jons - CR 1852MT 2009 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Crestliner C 1870 VS 2007 comes in at 2 lbs per hp versus 11 lbs per hp for the Crestliner Jons - CR 1852MT 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.
