*The Polyform US Fender Guide is to be used as a general guide. Common sense, as well as an understanding of your boat and mooring conditions, must be considered. The final responsibility has to be taken by the consumer due to many variables out of Polyform's control.

Fender Tips

Use at least three fenders when docking.

  1. Tie fenders to something solid like a stanchion base or deck cleat along the rail.
  2. Always hang fenders close enough to the surface of the water.
  3. Do not tie them high. This prevents them from swinging in a wide arc and winding up on top of the dock rather than between your hull and the dock where they belong.

Docking

Use at least three fenders when docking.

  1. One fender at aft.
  2. One fender at maximum beam.
  3. One fender at fore.

Rafting

  1. When rafting, the best fendering technique is to have the fenders in place on the boat already moored or at anchor.
  2. Group three standard fenders rather close to maxiumu beam. One fender at fore.
  3. Position two round A Series or LD Series buoys fore and aft to provide greater protection from boats tossing into each other.
