Section 63. Certificate of inspection

The inspector, if satisfied that a
  public vessel is in all respects safe and conforms to the requirement of
  this chapter, shall make and subscribe  duplicate  certificates  setting
  forth  the  name  and  number  of  the  vessel,  its  age,  the  date of
  inspection, the name of the owner, the number of licensed  officers  and
  crew  necessary to manage the vessel with safety, equipment required and
  any special restrictions or remarks pertaining to the operation  of  the
  vessel  and  the  number  of  passengers she can safely carry, and, if a
  steam vessel, the age of the boiler and the pressure  of  steam  she  is
  authorized  to  carry.  One of said certificates shall be kept posted in
  some conspicuous place on the vessel to be designated by  the  inspector
  and the other copy shall be kept by the inspector and by him recorded in
  a book to be kept for that purpose.  If the inspector refuses to grant a
  certificate  of  approval,  he shall make a statement in writing, giving
  his reasons for such refusal, and deliver  the  same  to  the  owner  or
  master  of  the  vessel. The posting of certificates of inspection shall
  not be required on vessels of less than ten tons  burden.  However  said
  certificates must be aboard whenever the vessel is in operation.
