27Enforcement of directions
(1)Without prejudice to any other remedy available to the Authority, if a special direction is not complied with within a reasonable time, the harbour master may, where practicable, put persons aboard the vessel to carry out the direction or may otherwise cause the vessel to be handled in accordance with the direction.
(2)If there is no one on board a vessel to attend to a special direction, the harbour master may proceed as if the direction had been given and not complied with:
Provided that the powers of this subsection shall not be exercised—
(a)in relation to a vessel other than a lighter, unless after reasonable inquiry has been made the master cannot be found; or
(b)in relation to a lighter, unless it is obstructing the access to or exit from a dock or otherwise interfering with navigation.
(3)Expenses incurred by the Authority in the exercise of the powers conferred by subsection (1) of this section shall be recoverable by the Authority as a simple contract debt.
