Any officer concerned in the collection of the revenue may at all times inspect the certificate of documentation of any documented vessel or any document in lieu thereof; and if the master or other person in charge or command of any such vessel shall not exhibit the same, when required by such officer, unless the vessel is one which by regulation of the Secretary of Transportation is not required to have its certificate of documentation or document in lieu thereof on board, such master or person in charge or command shall be liable to a penalty of $100, unless the failure to do so is willful, in which case he shall be liable to a penalty of $1,000 and to a fine of not more than $1,000 or imprisonment for not more than one year, or both.
