Stand watch in ships' bows, sterns, or bridge wings. Look out for obstructions in the ship's path and locate navigational aids such as buoys. Determine geographical position of the ship, using all available means such as GPS, radar ranges, visual observations and depth sounders. Perform navigational watches while underway, and safety watches, anchor watches and dock watches at other times as deemed prudent by the Captain, in accordance with normal bridge management procedures.
