144. Which color of rockets, shells, or rocket parachute flares are used to indicate that the vessel is in distress and requires immediate assistance?
Red rockets, shells, and rocket parachute flares are internationally recognized distress signals indicating a vessel requires immediate assistance, as defined in the Navigation Rules (COLREGS) Annex IV. Other colors are used for illumination or warning, not distress.
