Crestliner Fish Hawk 1750 DC 2011 vs Crestliner Sportfish 1800 I/O 2007 — Same Brand, Different Boat

The Crestliner Fish Hawk 1750 DC 2011 vs Crestliner Sportfish 1800 I/O 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 1750 DC 2011 at 17,5 ft versus Crestliner Sportfish 1800 I/O 2007 at 18,0 ft. Weight tells a clearer story for trailering families: the Crestliner Sportfish 1800 I/O 2007 tips the scales at 2 105 lbs — 2 094 lbs less than the Crestliner Fish Hawk 1750 DC 2011 at 11 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.

Both boats share a closely matched power ceiling — 125 hp for the Crestliner Fish Hawk 1750 DC 2011 and 135 hp for the Crestliner Sportfish 1800 I/O 2007. 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 Sportfish 1800 I/O 2007 carries 33 gallons versus 24 gallons in the Crestliner Fish Hawk 1750 DC 2011. 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 Sportfish 1800 I/O 2007 is rated for 7 passengers, while the Crestliner Fish Hawk 1750 DC 2011 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner Sportfish 1800 I/O 2007 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Crestliner Fish Hawk 1750 DC 2011 comes in at 0 lbs per hp versus 16 lbs per hp for the Crestliner Sportfish 1800 I/O 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: Choose the Crestliner Sportfish 1800 I/O 2007 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 1750 DC 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.

Crestliner Fish Hawk 1750 DC 2011 vs Crestliner Sportfish 1800 I/O 2007 — Common Questions

Which is the larger boat — the Crestliner Fish Hawk 1750 DC 2011 or the Crestliner Sportfish 1800 I/O 2007?
The Crestliner Sportfish 1800 I/O 2007 is the longer of the two at 18,0 feet overall. The Crestliner Fish Hawk 1750 DC 2011 comes in at 17,5 feet, making it roughly 0,5 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Crestliner Fish Hawk 1750 DC 2011 or the Crestliner Sportfish 1800 I/O 2007?
For trailering, the Crestliner Fish Hawk 1750 DC 2011 has the edge at 11 lbs dry weight versus 2 105 lbs for the Crestliner Sportfish 1800 I/O 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 Sportfish 1800 I/O 2007 is rated to a maximum of 135 hp, giving it the larger power ceiling. The Crestliner Fish Hawk 1750 DC 2011 tops out at 125 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 1750 DC 2011 is Coast Guard rated for 6 passengers, while the Crestliner Sportfish 1800 I/O 2007 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 1750 DC 2011 has a better power-to-weight ratio at 0 lbs per hp compared to 16 lbs per hp for the Crestliner Sportfish 1800 I/O 2007. 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 1750 DC 2011 and Crestliner Sportfish 1800 I/O 2007 share an 95 in. (242 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.
Which boat has the larger fuel tank — the Crestliner Fish Hawk 1750 DC 2011 or the Crestliner Sportfish 1800 I/O 2007?
The Crestliner Sportfish 1800 I/O 2007 has the bigger tank at 33 gallons, versus 24 gallons on the Crestliner Fish Hawk 1750 DC 2011. That 9-gallon difference translates to roughly 27–45 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Crestliner Fish Hawk 1750 DC 2011 and Crestliner Sportfish 1800 I/O 2007 from the same manufacturer?
Yes — both the Crestliner Fish Hawk 1750 DC 2011 and the Crestliner Sportfish 1800 I/O 2007 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.
