The Crestliner Ambush 18 2012 is a modified-V design and the Crestliner Grand Cayman 2185 2008 is a pontoon design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

On paper these two are close siblings in the size department - Crestliner Ambush 18 2012 at 18,0 ft versus Crestliner Grand Cayman 2185 2008 at 20,0 ft. Weight tells a clearer story for trailering families: the Crestliner Grand Cayman 2185 2008 tips the scales at 2 000 lbs - 991 lbs less than the Crestliner Ambush 18 2012 at 1 009 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 115 hp, the Crestliner Grand Cayman 2185 2008 has a 25-hp advantage over the Crestliner Ambush 18 2012's 90-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 22 gal and 25 gal - so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Crestliner Grand Cayman 2185 2008 is rated for 12 passengers, while the Crestliner Ambush 18 2012 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner Grand Cayman 2185 2008 could be the deciding factor.
