Assuming you mean the baseline for the purposes of territorial waters
etc, it is based on the low water line. There are rules which allow the
baseline to cut across inlets, bays, estuaries etc. So I would invert
your statement: the "political" baseline is the low water line, although
sometimes it is further out to sea.
