Question 9Navigation General

The correct answer is C) lockmaster. The lockmaster has full authority and responsibility for the operation and management of the lock, including the lock approach channels. This authority is granted by regulations set forth by the U.S. Army Corps of Engineers, which oversees the operation of locks and dams throughout the United States. The lockmaster is responsible for controlling vessel traffic, ensuring safe passage through the lock, and maintaining order within the lock area. The other options are incorrect because the dockmaster, lock foreman, and dock captain do not have the same level of authority as the lockmaster within the lock area. Their responsibilities are typically more limited in scope and do not extend to the full lock approach channels.
