Control of the territorial waters
While there is no fence along Gaza 's coastline, residents do not have open access to the sea. Palestinians wanting to go to sea need to request a permit from Israel. Those who obtain a permit are not allowed to sail far from shore. Anyone who violates the prohibition puts his life at risk: in the past, Israeli patrol boats have fired at boats that exceeded the maximum distance allowed. Israel 's Navy patrols the waters and thwarts attempts to enter or leave Gaza by sea.
