Crestliner Ambush 18 2013 vs Crestliner Fish Hawk 1850 SC 2006 — Same Brand, Different Boat

The Crestliner Ambush 18 2013 vs Crestliner Fish Hawk 1850 SC 2006 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

On paper these two are close siblings in the size department — Crestliner Ambush 18 2013 at 18,0 ft versus Crestliner Fish Hawk 1850 SC 2006 at 18,0 ft. Weight tells a clearer story for trailering families: the Crestliner Ambush 18 2013 tips the scales at 1 009 lbs — 996 lbs more than the Crestliner Fish Hawk 1850 SC 2006 at 13 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 150 hp, the Crestliner Fish Hawk 1850 SC 2006 has a 60-hp advantage over the Crestliner Ambush 18 2013's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Crestliner Fish Hawk 1850 SC 2006 carries 31 gallons versus 2 gallons in the Crestliner Ambush 18 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Crestliner Fish Hawk 1850 SC 2006 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 Fish Hawk 1850 SC 2006 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Crestliner Fish Hawk 1850 SC 2006 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.

Bottom line: Choose the Crestliner Fish Hawk 1850 SC 2006 if your priority is putting more people on the water — it handles 6 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Crestliner Ambush 18 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
