Three short blasts of a horn signal indicates that the vessel is backing up. This is a commonly used signal to warn nearby vessels of the action the vessel is about to take. Option A, vessel in distress, would typically be signaled by continuous blasts of the horn. Option B, vessel is slowing down, is signaled by two prolonged blasts of the horn. Option C, vessel is turning right, is indicated by one blast of the horn. Therefore, options A, B, and C are incorrect in the context of three short blasts of a horn signal.
