Rescue of people in distress at sea, regardless of their nationality or status, is an unconditional obligation for all ships in vicinity and coastal state authorities. The 1982 United Nations Convention on the Law of the Sea (UNCLOS Convention) provides that:
“ Every State shall require the master of a ship flying its flag, in so far as he can do so without serious danger to the ship, the crew or the passengers: (a) to render assistance to any person found at sea in danger of being lost; (b) to proceed with all possible speed to the rescue of persons in distress, if informed of their need of assistance, in so far as such action may reasonably be expected of him.” (Art. 98 (1))
