Crestliner C 1860 VDC 2005 vs Crestliner Fish Hawk 1850 Tiller 2006 — Same Brand, Different Boat

The Crestliner C 1860 VDC 2005 vs Crestliner Fish Hawk 1850 Tiller 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 C 1860 VDC 2005 at 18,0 ft versus Crestliner Fish Hawk 1850 Tiller 2006 at 18,0 ft. At 77 lbs and 125 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

Both boats share a closely matched power ceiling — 90 hp for the Crestliner C 1860 VDC 2005 and 90 hp for the Crestliner Fish Hawk 1850 Tiller 2006. 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. Fuel capacity breaks the other way: the Crestliner Fish Hawk 1850 Tiller 2006 carries 31 gallons versus 21 gallons in the Crestliner C 1860 VDC 2005. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

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 C 1860 VDC 2005 comes in at 1 lbs per hp versus 1 lbs per hp for the Crestliner Fish Hawk 1850 Tiller 2006. 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: The Crestliner C 1860 VDC 2005 and Crestliner Fish Hawk 1850 Tiller 2006 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
