Counterfeits are everywhere. The UK Hydrographic Office, UKHO, has issued a warning that fake Admiralty charts are in circulation which, because they are not official publications, do not meet carriage requirements of the International Convention on the Safety of Life at Sea (see Chapter V, Regulations 2.2 and 188.8.131.52 of the Convention). Likewise their carriage may not satisfy the requirements of (and may be contrary to) the local laws of Flag State Authorities and Port State Controls.
Says UKHO: “Counterfeit products have not undergone the rigorous checking procedures which take place for official products and they cannot be trusted in the same way. Their use may increase the safety risk to vessels, crews and cargoes”.
