When two boats share the same hull type — in this case both the Crestliner Ambush 18 2013 and the Crestliner Retriever 2070 CC 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?

Size is the most obvious dividing line here. The Crestliner Ambush 18 2013 measures 18,0 feet overall (2013), giving it roughly 16,0 additional feet of deck space compared to the Crestliner Retriever 2070 CC 2011 at 2,0 feet (2011). Weight tells a clearer story for trailering families: the Crestliner Ambush 18 2013 tips the scales at 1 009 lbs — 892 lbs more than the Crestliner Retriever 2070 CC 2011 at 117 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 Ambush 18 2013 and 90 hp for the Crestliner Retriever 2070 CC 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 Retriever 2070 CC 2011 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 Retriever 2070 CC 2011 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Crestliner Retriever 2070 CC 2011 comes in at 1 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.
