Without affecting any other remedy available to the Trustees, if a special direction is not complied with within a reasonable time, the harbour master may, where practicable, put persons on board the vessel to carry out the direction or may otherwise cause the vessel to be handled in accordance with the direction.

If there is no one on board the vessel to comply with a special direction, the harbour master may proceed as if the direction had been given and not complied with; but he shall not do so unless, after reasonable inquiry has been made, the master cannot be found.

Reasonable expenses incurred in the exercise of the powers conferred by this article shall be recoverable by the Trustees from the owner of the vessel as if they were a charge of the Trustees in respect of the vessel.
