Whenever the Harbor Master finds it necessary for safe navigation or safety of the Port or harbor, he may order the Master or other person in charge of any vessel or watercraft to change its position or to change the position of the rigging, cargo, booms, or other equipment, or to do any other act necessary to remove obstruction to safe navigation.  If the Master or other person in charge of the vessel fails or refuses to comply with the order of the Harbor Master, then the Harbor Master or his/her authorized representatives may remove the obstruction to navigation; and any expense resulting therefrom may be recovered by an action by law, if necessary.
