The Fisher Liberty 180 2006 vs Fisher Pro Hawk 170 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 — Fisher Liberty 180 2006 at 18,0 ft versus Fisher Pro Hawk 170 2005 at 17,0 ft. Weight tells a clearer story for trailering families: the Fisher Liberty 180 2006 tips the scales at 166 lbs — 155 lbs more than the Fisher Pro Hawk 170 2005 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 — 75 hp for the Fisher Liberty 180 2006 and 90 hp for the Fisher Pro Hawk 170 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. Fuel capacity breaks the other way: the Fisher Pro Hawk 170 2005 carries 25 gallons versus 19 gallons in the Fisher Liberty 180 2006. 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 2006 is rated for 7 passengers, while the Fisher Pro Hawk 170 2005 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 2006 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Fisher Pro Hawk 170 2005 comes in at 0 lbs per hp versus 2 lbs per hp for the Fisher Liberty 180 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.
The Fisher Liberty 180 2006 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 2005 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 2006 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 Fisher Pro Hawk 170 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
