Do you need to report to a harbor master when entering a foreign port?

When entering a foreign port, the master of the vessel needs to clear both the yacht and all crew and guests into the port via the proper Port Authorities for that country and port, which may or may not be a Harbour Master. As a foreign flag entering a foreign port all vessels and crew/passengers must be officially cleared in by the proper authorities before any crew or passengers leave the ship and set foot ashore.
