I think it's interesting that her love is lost at sea, and she very much is too. The town is described as rain swept, with "sea salt tears swimming round as the rain comes down". These are very direct references to ocean water. Hence, it seems that she, too, is lost without her lover, in her town which is so like the sea. Both are lost at sea without each other, so the title could be from the perspective of either lover.
