acknowledge the signal, do so by hoisting the signal close up, bearing in mind the ship's visual responsibility. This notifies the originator that your ship understands the signal and is ready to carry out any required action. When the originator lowers the hoist, haul down your hoist smartly and inform the OOD that the signal has been hauled down. When an addressee desires to question a signal, the signal or ANS shall be kept at the dip, and the INTERROGATIVE pennant hoisted on an adjacent halyard. Normally, an address over INT will not be required when communication is only between the originator and the addressee questioning the signal. When necessary to refer to the signal of a specific originator, a call may precede INT. NOTE INT signals need not be acknowledged if the signal in question can be clarified, hoisted, or canceled immediately. However, when answered and brought close up on both ships, INT signals should be hauled down to free the halyards for additional signals. In addition to the provisions for the use of the INTERROGATIVE pennant used alone, it may be amplified and used as follows: INT l—Signal now flying not distinguishable. INT 2—You are repeating signal incorrectly. INT 3—I am repeating signal incorrectly. These signals are most effective in expediting flaghoist signaling when passed by flashing light. Once a problem has been identified, regardless of ship (be it the originator, repeating ship, or last ship in visual chain of responsibility), adherence to the procedures for canceling or correcting a hoist are of paramount importance in avoiding early execution or delay and/or confusion in the receipt of the intended signal. Requests may be acknowledged by a senior officer by hoisting flag CHARLIE or NEGAT below the call of the ship making the request. Such signals constitute both receipt and answer. CANCELING A SIGNAL Flaghoist signals are canceled by the following uses of NEGAT: 5-14 When only one flag signal is flying, NEGAT hoisted on an adjacent halyard cancels the signal. When two or more flag signals are flying under the same call, NEGAT hoisted on an adjacent halyard cancels all signals flying. If only one signal is to be canceled, it must be repeated preceded by NEGAT. When “all ships” signals and specifically addressed signals are flying at the same time, NEGAT without a call preceding it cancels all signals without a call, and NEGAT with a call preceding it cancels all signals under a similar call. If only one signal of several signals under the same call is to be canceled, it must be repeated and preceded by NEGAT under the same call. The canceling signal and the signal canceled are to be hauled down together when all addressees have acknowledged. CORRECTING A SIGNAL Flaghoist signals are corrected as follows: An originating ship cancels the signal in question, then hoists the correct signal. A repeating ship hoists the signal meaning “Signal is repeated incorrectly” on an adjacent halyard, then hauls down both signals. The correct signal is then hoisted. EXPEDITING OF FLAGHOIST SIGNALING An originating ship may pass its signal by flashing light if there is doubt that its flags can be seen clearly. Directional or nondirectional light, using proper procedure, can be used. The operating signal ZJL meaning “Hoist the following signal” can be included. Directional If directional procedure is used, the signal will be receipted for by light and acknowledged in the normal flaghoist manner. The executive signal need not be made by light when the signal is hauled down. Nondirectional If nondirectional procedure is used and no ship will answer, the signal may be repeated as often as necessary, with repetitions being separated by the prosign IMI. Ships will acknowledge by flaghoist. The
