"cove with pushing prow..."See in text(Text of the Poem)
A “cove” is a small inlet or bay on the coast, small and sheltered in contrast to the open sea. “Prow” refers to the bow of a ship or boat rides above the water. The immediate alliteration of the “p” sound in “pushing prow” quickens the rhythm in the line and suggests that the speaker is driven and impatient to reach land.
