Pan-pan: This is the second most important call. This call is made when there is an emergency aboard a vessel, yet there is not immediate danger to life, or the safety of the vessel itself. This includes, but is not limited to injuries on deck, imminent collision that has not yet occurred, or being unsure of vessel's position.
