The certificate of inspection issued to a vessel carrying more than six passengers must be posted on board under glass, if practicable. Which option matches this requirement?

• A. Displayed on an outside window
• B. Posted at the dock only
• C. Posted on board under glass, if practicable
• D. Forward of the wheelhouse

Answer: (C)

The main concept is that for vessels carrying more than six passengers, the certificate of inspection must be posted on board and, if practicable, kept under glass. This ensures the certificate is readily visible to passengers and inspectors and protected from weather and tampering. The best match is posting the certificate on board under glass, if practicable, because it fulfills both requirements: it’s on the vessel itself and protected when possible. Displaying it on an outside window or posting only at the dock would not guarantee it’s on board or protected, and placing it in a specific spot like forward of the wheelhouse isn’t required by the rule.
