Title 46 - Shipping
The Certificate of Inspection and any SOLAS Certificates must be posted under glass or other suitable transparent material, such that all pages are visible, in a conspicuous place on the vessel where observation by passengers is likely. If posting is impracticable, such as in an open boat, the certificates must be kept on board in a weathertight container readily available for use by the crew and display to passengers and others on request.
