ENDORSEMENT OF CERTIFICATES.

54. The holder of an ordinary certificate may have it endorsed to the effect that he is competent for service in the appropriate capacity in motor-ships, provided that he produces proof of at least nine months’ qualifying service in the foreign or intercolonial trade, or thirteen and a half months’ service in a qualifying capacity in the home trade, in motor-ships of horse-power not less than that required by these rules, and passes the appropriate examination.

The holder of a motor certificate may have it endorsed for service in steamships, provided that he proves at least twelve months’ service in a qualifying capacity in the foreign or intercolonial trade, or eighteen months’ qualifying service in the home trade, in steamships of horse-power not less than that required by these rules, and passes the appropriate examination.

Sea service in charge of a watch in vessels of the required horse-power performed by the holder of a second-class certificate, either ordinary or motor, whilst in possession thereof will be accepted as qualifying for first-class endorsement of either denomination, provided that in the case of an ordinary endorsement the necessary experience has been gained on both main engines and boilers of a steamship. (See Rule 60.)
