 In addition, the listing aims to encourage conscious private cultural heritage ownership and management.Owners of listed ships are entitled to display a plaque that confirms the ship's listed status on board, and pleasure boats are equipped with a similar enamel sign.While the listing does not confer any legal protection on the ships – in contrast to listed buildings – the Maritime Museum notes that listed ships and boats under some circumstances enjoy reduced harbour fees and listed pleasure boats sometimes enjoy various benefits by harbours, canals, dockyards and boat clubs.
