Most of the ferry wharves in Sydney seem to consist of piles with the decking set back behind the piles. This means there is a substantial gap between decking and your boat if you come alongside using a fender board to protect the topsides. The ferries carry gangplanks to bridge the gap.
What do our members do to solve this problem when picking up passengers?
I have seen someone with a bit of 4x2 hanging from his staunchons. Long enough to bridge the gap between the pylons. Bit of a pain carrying it around though.
When its windy I avoid at all costs. I think the pylons have a metal strip vertically which is worse.
When not windy you can hang a few fenders on their side, not the best but helps.
