Prohibitory scope

A.5 tells vessels not to berth on the side where the board is placed. Which interpretation is complete?

Short answer

It is prohibitory and removes both anchoring and making fast on that side

A.5 is a prohibitory sign, and CEVNI defines its no-berthing scope as no anchoring or making fast to the bank on that side. Treating it as advice or changing securing method preserves the same prohibited outcome. Revisit Prohibitions: Know What Is Actually Forbidden.
