In "Sea Fever," where does the poet go and why?

This excellent and memorable poem is all about the intense
desire of the speaker to return to the sea, which obviously is very important to his
identity and life. From the very first line of this poem, the longing that the speaker
has to return to the sea speaks of the "Sea Fever" of the title, and the way that his
love of the sea is an obsession for him, that makes it impossible for him to live inland
for too much time:

I must go down to the seas again, to the lonely
sea and the sky...

His
longing to sail out and live the "vagrant gyspy life" by himself with nothing but a ship
and the various animals and birds that are found on the sea are expressed throughout the
poem, which could be described as a love poem about one man's desire and intense
connection with the sea and the kind of life that a sailor can lead. The speaker is
obviously unsatisfied with his life on shore, and finds something irresistably
attractive and romantic about the life of a sailor. Note how it is
described:

To
the gull's way and the whale's way where the wind's like a whetted
knife...

The beauty, thrill
and excitement that is evoked in such lines makes it clear how attractive the sea is to
the speaker and why he wishes to return there.
