Before airing bunting, obtain permission from the senior officer present afloat (SOPA) Signalmen must always be mindful that an alert signal force is the mark of a smart ship. The following items make for smartness in flaghoist signaling: Accuracy in bending on the correct flag the first time Smoothness in hoisting and making a quick turn with the uphaul Speed in hauling up the hoist Assurance that all flags are sent up clear Certainty that the signal is kept visible while the hoist is flying. The downhaul is kept fairly taut Signals are hauled down sharply, smoothly, and in such manner that they are not allowed to stream to leeward or over the side 8-2
