What the AI looks for in Boat Fenders
- Diameter
- Allow about 1 inch of fender diameter per 4 to 5 feet of boat length, and size up for heavy boats or rough berths. Undersized fenders squash flat and let the hull touch the dock.
- Count
- Carry at least three fenders, adding about one per 10 feet of length. This covers the contact area at the bow, amidships and stern.
- Shape
- Cylindrical fenders suit side-tie docks. Round ball fenders suit pilings, rafting and flared bows. Shape determines how the fender stays in place.
- Adjustable inflation
- Prefer fenders with an air valve. Pressure can then be set for firmness and replaced after temperature changes.
Brands that matter
- Polyform: Thick-walled inflatable fenders and buoys.
- Taylor Made: Major fender maker with several lines.
What to avoid
- Thin-walled fenders that wrinkle and burst
- Fenders hung without fender covers on gelcoat-sensitive hulls in gritty water
- Too few or too small fenders for the boat
