Fenders and Lines for Seawalls
Fender boards and fenders to the rescue.
To the lubber, tying-up to a bulkhead seems like the simplest of all docking situations. Perhaps with floating docks this is true. You just throw in a few fenders and tie a few lines. Simple. But in the world of tidal bulkheads with pilings or rough concrete facings, it is often a hammer and anvil situation, with the wind and waves hammer incessantly as the anvil moves up and down with the tide, causing fenders to slip out of position.
