*The Polyform U.S. 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 the many variables out of Polyform's Control.

Fendering Tips:

Every docking situation is different, and fenders make docking safer but they can't protect your boat in all conditions. However, there are a few things you can do to help get the most protection . Tie fenders to something solid like a stanchion base or deck cleat along the rail and don't tie to lifelines which are not designed to handle the pressure of rough or tidal conditions. Always hang fenders close enough to the surface of the water that they can't be pushed up by the moverment of the boat against the dock, and make sure to tie your fenders in as low as possible 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.

Polyform fendering tips

Docking

Use at least three fenders when docking - one at maximum beam, one each at fore and aft.

Rafting

Polyform fender guide for raftingWhen rafting, the best fendering technique is to have the fenders in place on the boat already moored or at anchor. Group three standard fenders rather close to maximum beam, then position two round A Series or LD Series buoys fore and aft to provide greater protection from boats tossing into each other.
