A stanza is a group of lines in a poem (I've seen from 4-8 lines) that the poet can use to establish his/her rhyme scheme and move the poem on through its story. This may not be exactly what you're looking for, but good luck.
"When race of wind is stilled and sails are furled" is an symbolic phrase that has a different meaning from its literal one. The symbolic meaning of the phrase is this, 'It implies chaos or a lack of control.' It has something to do with the coming event that will happen.
