Crestliner Fish Hawk 1850 SC 2005 vs Crestliner Fish Hawk 1850 Tiller 2007 — Same Brand, Different Boat

The Crestliner Fish Hawk 1850 SC 2005 vs Crestliner Fish Hawk 1850 Tiller 2007 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 Fish Hawk 1850 SC 2005 at 18,0 ft versus Crestliner Fish Hawk 1850 Tiller 2007 at 18,0 ft. Weight tells a clearer story for trailering families: the Crestliner Fish Hawk 1850 Tiller 2007 tips the scales at 125 lbs — 112 lbs less than the Crestliner Fish Hawk 1850 SC 2005 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 2005 has a 60-hp advantage over the Crestliner Fish Hawk 1850 Tiller 2007'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 — 31 gal and 31 gal — so range won't be a tiebreaker here.

Both boats are rated for 6 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

At this size, power-to-weight ratio matters more than outright horsepower. The Crestliner Fish Hawk 1850 SC 2005 comes in at 0 lbs per hp versus 1 lbs per hp for the Crestliner Fish Hawk 1850 Tiller 2007. 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: Performance buyers should lean toward the Crestliner Fish Hawk 1850 SC 2005 and its 150-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Crestliner Fish Hawk 1850 Tiller 2007 with its 90-hp rating is the more economical daily driver.
