Certificates and permits
April 15, 2021
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.
