When two boats share the same hull type — in this case both the Crestliner Ambush 18 2013 and the Crestliner CR 1852 MT 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 Ambush 18 2013 at 18,0 ft versus Crestliner CR 1852 MT 2008 at 18,0 ft. Weight tells a clearer story for trailering families: the Crestliner Ambush 18 2013 tips the scales at 1 009 lbs — 1 005 lbs more than the Crestliner CR 1852 MT 2008 at 4 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 Ambush 18 2013 has a 45-hp advantage over the Crestliner CR 1852 MT 2008'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 CR 1852 MT 2008 is rated for 6 passengers, while the Crestliner Ambush 18 2013 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner CR 1852 MT 2008 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Crestliner CR 1852 MT 2008 comes in at 0 lbs per hp versus 11 lbs per hp for the Crestliner Ambush 18 2013. 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.
