Fisher Liberty 180 2007 vs Fisher Pro Hawk 170 2004 — Same Brand, Different Boat

The Fisher Liberty 180 2007 vs Fisher Pro Hawk 170 2004 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.

Both boats share a closely matched power ceiling — 75 hp for the Fisher Liberty 180 2007 and 90 hp for the Fisher Pro Hawk 170 2004. 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 Fisher Liberty 180 2007 carries 19 gallons versus 3 gallons in the Fisher Pro Hawk 170 2004. 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 Fisher Liberty 180 2007 is rated for 7 passengers, while the Fisher Pro Hawk 170 2004 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Fisher Liberty 180 2007 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Fisher Pro Hawk 170 2004 comes in at 0 lbs per hp versus 2 lbs per hp for the Fisher Liberty 180 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.

The Fisher Liberty 180 2007 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Fisher Pro Hawk 170 2004 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.

Bottom line: Choose the Fisher Liberty 180 2007 if your priority is putting more people on the water — it handles 7 passengers and at 19,0 ft it has the deck room to back that rating up comfortably. The Fisher Pro Hawk 170 2004 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.

Fisher Liberty 180 2007 vs Fisher Pro Hawk 170 2004 — Common Questions

Which is easier to trailer — the Fisher Liberty 180 2007 or the Fisher Pro Hawk 170 2004?
For trailering, the Fisher Pro Hawk 170 2004 has the edge at 11 lbs dry weight versus 141 lbs for the Fisher Liberty 180 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 Fisher Pro Hawk 170 2004 is rated to a maximum of 90 hp, giving it the larger power ceiling. The Fisher Liberty 180 2007 tops out at 75 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 Fisher Liberty 180 2007 is Coast Guard rated for 7 passengers, while the Fisher Pro Hawk 170 2004 is certified for 4. 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 is wider, and does it affect trailering?
The Fisher Liberty 180 2007 measures 98" wide, compared to 87" for the Fisher Pro Hawk 170 2004. 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.
Which boat has the larger fuel tank — the Fisher Liberty 180 2007 or the Fisher Pro Hawk 170 2004?
The Fisher Liberty 180 2007 has the bigger tank at 19 gallons, versus 3 gallons on the Fisher Pro Hawk 170 2004. That 16-gallon difference translates to roughly 48–80 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Fisher Liberty 180 2007 and Fisher Pro Hawk 170 2004 from the same manufacturer?
Yes — both the Fisher Liberty 180 2007 and the Fisher Pro Hawk 170 2004 are built by Fisher. 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.
