The Fisher 1710 2004 vs Fisher Liberty 180 2007 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 1710 2004 and 75 hp for the Fisher Liberty 180 2007. 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 13 gallons in the Fisher 1710 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 1710 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 Liberty 180 2007 comes in at 2 lbs per hp versus 12 lbs per hp for the Fisher 1710 2004. 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 1710 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 1710 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.
