Where because of the presence of a delta and other natural conditions the coastline is highly unstable, the appropriate points may be selected along the furthest seaward extent of the low-water line and, notwithstanding subsequent regression of the low-water line, the straight baselines shall remain effective until changed by the coastal State in accordance with this Convention.
Ako je zbog postojanja delte i drugih prirodnih uvjeta obalna crta izrazito nestabilna, prikladne se točke mogu izabrati uzduž najudaljenije crte niske vode u smjeru mora i, usprkos kasnijem povlačenju crte niske vode, ravne polazne crte ostaju valjanima sve dok ih obalna država ne izmijeni.
