In the poem, the speaker is describing the allure of the sea, which he sees as a wild and unpredictable force that calls to him like a siren song. He longs for the freedom and adventure of a life at sea, even if it means being constantly on the move and facing the unknown.
The "vagrant gypsy life" is a way of capturing this sense of unrestrained wandering and the thrill of constant exploration. The sea, like a gypsy, is always moving and changing, and those who sail upon it embrace this restless spirit.
