Matching a deep vee Fisher 16 Pro Avenger WT 2008 against a pontoon Fisher Liberty 180 Fish 2009 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
On paper these two are close siblings in the size department — Fisher 16 Pro Avenger WT 2008 at 16,0 ft versus Fisher Liberty 180 Fish 2009 at 18,0 ft. Weight tells a clearer story for trailering families: the Fisher Liberty 180 Fish 2009 tips the scales at 1 755 lbs — 561 lbs less than the Fisher 16 Pro Avenger WT 2008 at 1 194 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 16 Pro Avenger WT 2008 and 75 hp for the Fisher Liberty 180 Fish 2009. 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 16 Pro Avenger WT 2008 carries 24 gallons versus 19 gallons in the Fisher Liberty 180 Fish 2009. 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 2009 is rated for 7 passengers, while the Fisher 16 Pro Avenger WT 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 2009 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Fisher 16 Pro Avenger WT 2008 comes in at 16 lbs per hp versus 23 lbs per hp for the Fisher Liberty 180 Fish 2009. 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 Fisher Liberty 180 Fish 2009 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 16 Pro Avenger WT 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.
