Two sided Sound Signals Cockpit Card.
Side 1 depicts signals sounded by vessels in sight of one another and those sounded by power vessels in a narrow channel.
Side 2 depicts fog signals for both day and night.
Cockpit Cards are a series of quick reference nautical cards designed to withstand the harsh environment of life afloat. The crisp clear images are printed to a very high standard using 'light-fast ink'. They are encapsulated rather than laminated using a heavy duty plastic and will provide years of sailing use and abuse.
