Crestliner C 1870 VS 2007 vs Crestliner Fish Hawk 1650 Tiller 2005 — Same Brand, Different Boat

The Crestliner C 1870 VS 2007 vs Crestliner Fish Hawk 1650 Tiller 2005 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 1870 VS 2007 at 18,0 ft versus Crestliner Fish Hawk 1650 Tiller 2005 at 16,0 ft. At 115 lbs and 88 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 — 75 hp for the Crestliner C 1870 VS 2007 and 60 hp for the Crestliner Fish Hawk 1650 Tiller 2005. 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.

Both boats are rated for 5 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 1650 Tiller 2005 comes in at 2 lbs per hp versus 2 lbs per hp for the Crestliner C 1870 VS 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: The Crestliner C 1870 VS 2007 and Crestliner Fish Hawk 1650 Tiller 2005 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.

The Crestliner C 1870 VS 2007 is the longer of the two at 18,0 feet overall. The Crestliner Fish Hawk 1650 Tiller 2005 comes in at 16,0 feet, making it roughly 2,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Crestliner C 1870 VS 2007 or the Crestliner Fish Hawk 1650 Tiller 2005?
For trailering, the Crestliner Fish Hawk 1650 Tiller 2005 has the edge at 88 lbs dry weight versus 115 lbs for the Crestliner C 1870 VS 2007. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Crestliner C 1870 VS 2007 is rated to a maximum of 75 hp, giving it the larger power ceiling. The Crestliner Fish Hawk 1650 Tiller 2005 tops out at 60 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Crestliner C 1870 VS 2007 is Coast Guard rated for 5 passengers, while the Crestliner Fish Hawk 1650 Tiller 2005 is certified for 5. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat has the better power-to-weight ratio?
The Crestliner Fish Hawk 1650 Tiller 2005 has a better power-to-weight ratio at 2 lbs per hp compared to 2 lbs per hp for the Crestliner C 1870 VS 2007. A lower number means quicker acceleration and faster time to plane — the number that actually matters most on short, sporty boats like these.
Which boat is wider, and does it affect trailering?
The Crestliner C 1870 VS 2007 measures 91" wide, compared to 87" for the Crestliner Fish Hawk 1650 Tiller 2005. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Are the Crestliner C 1870 VS 2007 and Crestliner Fish Hawk 1650 Tiller 2005 from the same manufacturer?
Yes — both the Crestliner C 1870 VS 2007 and the Crestliner Fish Hawk 1650 Tiller 2005 are built by Crestliner. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
