The Fisher Hawk 170 SC 2008 vs Fisher Liberty 180 Fish 2006 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 Hawk 170 SC 2008 at 17,0 ft versus Fisher Liberty 180 Fish 2006 at 18,0 ft. Weight tells a clearer story for trailering families: the Fisher Hawk 170 SC 2008 tips the scales at 1 325 lbs — 1 173 lbs more than the Fisher Liberty 180 Fish 2006 at 152 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 150 hp, the Fisher Hawk 170 SC 2008 has a 75-hp advantage over the Fisher Liberty 180 Fish 2006's 75-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Fisher Liberty 180 Fish 2006 carries 19 gallons versus 3 gallons in the Fisher Hawk 170 SC 2008. 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 Fish 2006 is rated for 7 passengers, while the Fisher Hawk 170 SC 2008 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Fisher Liberty 180 Fish 2006 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Fisher Liberty 180 Fish 2006 comes in at 2 lbs per hp versus 9 lbs per hp for the Fisher Hawk 170 SC 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.
The Fisher Liberty 180 Fish 2006 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Fisher Hawk 170 SC 2008 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 Fish 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 Hawk 170 SC 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
