Fisher 17 Pro Avenger SC 2007 vs Fisher Liberty 180 Fish 2005 — Same Brand, Different Boat

The Fisher 17 Pro Avenger SC 2007 vs Fisher Liberty 180 Fish 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 17 Pro Avenger SC 2007 at 17,0 ft versus Fisher Liberty 180 Fish 2005 at 18,0 ft. Weight tells a clearer story for trailering families: the Fisher 17 Pro Avenger SC 2007 tips the scales at 1 275 lbs — 1 123 lbs more than the Fisher Liberty 180 Fish 2005 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 Fisher 17 Pro Avenger SC 2007 carries a rated maximum of 135 hp. Engine data for the Fisher Liberty 180 Fish 2005 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Fisher Liberty 180 Fish 2005 carries 21 gallons versus 3 gallons in the Fisher 17 Pro Avenger SC 2007. 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 2005 is rated for 7 passengers, while the Fisher 17 Pro Avenger SC 2007 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 2005 could be the deciding factor.

Bottom line: Choose the Fisher Liberty 180 Fish 2005 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 17 Pro Avenger SC 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.

The Fisher Liberty 180 Fish 2005 is the longer of the two at 18,0 feet overall. The Fisher 17 Pro Avenger SC 2007 comes in at 17,0 feet, making it roughly 1,0 ft shorter — a meaningful difference in deck room and overall on-water presence.

How many people can each boat hold?
