Q: Which is easier to trailer — the Fisher 160 Pro Avenger SC 2004 or the Fisher Liberty 180 2005?

For trailering, the Fisher 160 Pro Avenger SC 2004 has the edge at 105 lbs dry weight versus 166 lbs for the Fisher Liberty 180 2005. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.

Q: What is the maximum horsepower rating for these boats?

The Fisher 160 Pro Avenger SC 2004 has a documented max rating of 90 hp. Engine specifications for the Fisher Liberty 180 2005 were not available in our database — check the OEM spec sheet or manufacturer's website for confirmation.

Q: How many people can each boat hold?

The Fisher 160 Pro Avenger SC 2004 is Coast Guard rated for 5 passengers, while the Fisher Liberty 180 2005 is certified for 7. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.

Q: Which boat is wider, and does it affect trailering?

The Fisher Liberty 180 2005 measures 97" wide, compared to 82" for the Fisher 160 Pro Avenger SC 2004. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.

Q: Which boat has the larger fuel tank — the Fisher 160 Pro Avenger SC 2004 or the Fisher Liberty 180 2005?

The Fisher 160 Pro Avenger SC 2004 has the bigger tank at 24 gallons, versus 21 gallons on the Fisher Liberty 180 2005. That 3-gallon difference translates to roughly 9–15 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Fisher 160 Pro Avenger SC 2004 and Fisher Liberty 180 2005 from the same manufacturer?

Yes — both the Fisher 160 Pro Avenger SC 2004 and the Fisher Liberty 180 2005 are built by Fisher. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.

Engine data for the Fisher Liberty 180 2005 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Both carry nearly identical fuel loads — 24 gal and 21 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Fisher Liberty 180 2005 is rated for 7 passengers, while the Fisher 160 Pro Avenger SC 2004 caps at 5.
