Crestliner Fish Hawk 1850 Tiller 2006 vs Crestliner Super Hawk 1800 I/O 2008 — Same Brand, Different Boat

The Crestliner Fish Hawk 1850 Tiller 2006 vs Crestliner Super Hawk 1800 I/O 2008 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 Tiller 2006 at 18,0 ft versus Crestliner Super Hawk 1800 I/O 2008 at 18,0 ft. Weight tells a clearer story for trailering families: the Crestliner Super Hawk 1800 I/O 2008 tips the scales at 2 105 lbs — 1 980 lbs less than the Crestliner Fish Hawk 1850 Tiller 2006 at 125 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 220 hp, the Crestliner Super Hawk 1800 I/O 2008 has a 130-hp advantage over the Crestliner Fish Hawk 1850 Tiller 2006'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 33 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Crestliner Super Hawk 1800 I/O 2008 is rated for 7 passengers, while the Crestliner Fish Hawk 1850 Tiller 2006 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner Super Hawk 1800 I/O 2008 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Crestliner Fish Hawk 1850 Tiller 2006 comes in at 1 lbs per hp versus 10 lbs per hp for the Crestliner Super Hawk 1800 I/O 2008. 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 Super Hawk 1800 I/O 2008 if your priority is putting more people on the water — it handles 7 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Crestliner Fish Hawk 1850 Tiller 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.

Which is easier to trailer — the Crestliner Fish Hawk 1850 Tiller 2006 or the Crestliner Super Hawk 1800 I/O 2008?
For trailering, the Crestliner Fish Hawk 1850 Tiller 2006 has the edge at 125 lbs dry weight versus 2 105 lbs for the Crestliner Super Hawk 1800 I/O 2008. 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 Super Hawk 1800 I/O 2008 is rated to a maximum of 220 hp, giving it the larger power ceiling. The Crestliner Fish Hawk 1850 Tiller 2006 tops out at 90 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 Fish Hawk 1850 Tiller 2006 is Coast Guard rated for 6 passengers, while the Crestliner Super Hawk 1800 I/O 2008 is certified for 7. 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 1850 Tiller 2006 has a better power-to-weight ratio at 1 lbs per hp compared to 10 lbs per hp for the Crestliner Super Hawk 1800 I/O 2008. A lower number means quicker acceleration and faster time to plane — the number that actually matters most on short, sporty boats like these.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Crestliner Fish Hawk 1850 Tiller 2006 and Crestliner Super Hawk 1800 I/O 2008 share an 95.5 in. (243 cm) beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
How do the fuel tanks compare on the Crestliner Fish Hawk 1850 Tiller 2006 and Crestliner Super Hawk 1800 I/O 2008?
Both boats carry similar fuel loads — 31 gallons and 33 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Crestliner Fish Hawk 1850 Tiller 2006 and Crestliner Super Hawk 1800 I/O 2008 from the same manufacturer?
Yes — both the Crestliner Fish Hawk 1850 Tiller 2006 and the Crestliner Super Hawk 1800 I/O 2008 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.
