The original purpose of the magnetic compass was to help sailors to know which direction they should point their ships while they were sailing beyond the sight of land. On the open sea, you need some way of figuring out where you are and in which direction your destination lies, since the sea is relatively featureless and looks pretty much the same everywhere.
