Multipurpose Lamp When using the portable multipurpose light (discussed in chapter 2) in a small boat, bear in mind that (1) it requires extra effort to keep the light accurately trained because of the boat's possible extreme pitch and roll, and that (2) consequently your rate of sending must be slower than normal. Semaphore When signaling by semaphore, use normal procedure but, again, transmit at a reduced rate of speed. If you have a poor background for sending, Signalmen on the ship may have difficulty reading your message. F l a g h o i s t The following signals are used to direct a lifeboat by flaghoist: EIGHT—Steer straight away from the ship. EIGHT PORT—Steer left; when hauled down, cease turn and steady on present course. EIGHT STBD—Steer right; when hauled down, cease turn and steady on present course. EIGHT SCREEN—Steer straight toward ship. QUEBEC—Return to ship. Personnel Qualification Standard for Visual Communications, NAVEDTRA 43354A, section 308, must be completed before a person can be qualified as a boat Signalman. IN-PORT DUTY SIGNALMAN LEARNING OBJECTIVE: Explain the duties of the in-port duty Signalman. The duties of the in-port duty Signalman range from standing a visual watch on the signal bridge to being a member of the rescue and assistance detail. Whatever your duty is, you as a Signalman must perform it to the best of your ability. Some of the duties you will perform in port are discussed in the following paragraphs. VISUAL WATCH Signal watches in port are normally stood between the hours of sunrise and sunset unless SOPA requires that a 24-hour visual watch be maintained. Signalmen on watch are required to report to the OOD all ships departing and arriving in port and the movement of small boats in the harbor, and to provide the OOD with advance warning of possible passing honors. COLORS/ABSENTEE PENNANTS The in-port duty Signalman is responsible for hoisting and hauling down PREP for sunrise, morning, and evening colors, and frequently signals morning and evening colors by whistle. The Signalman on watch also assures that the appropriate absentee indicator flies when the senior officers are ashore, and hauls it down when the officers return to the ship. Semaphore and flashing light are used in port for administrative traffic. Signal watches in port are as important as those at sea. Because fewer personnel are available for each watch, a signal watch in port can be more difficult than one at sea. Occasionally, a destroyer or smaller ship may get a tender to take its visual guard. Another possibility is that the squadron flagship may assign a rotating guard among ships in a nest. More frequently—especially aboard larger ships—each ship maintains its own visual watch in port. Before standing the duty as an in-port duty Signalman, you must complete Personnel Qualification Standard for Visual Communications, NAVEDTRA 43354A, section 307. STORM-WARNING SIGNALS LEARNING OBJECTIVES: List and define day and night storm-warning signals. The combinations of storm-warning flags, pennants, and light signals in figure 8-5 are hoisted or displayed at weather bureau facilities and other shore stations in the United States and its possessions to warn and indicate the severity of storms in the area. It should be noted that the four day and night storm-warning signals and their meanings are not international in their usage. The ability of a Signalman 8-15
