Here's what's in the sleeve notes to "The Gaugers" CD, "Awa' Wi' The Rovin' Sailor" :

"This is another song from the repertoire of Thomas Stott, Tom [ Spiers' ] grandfather, who came from the Buchan fishing village of Collieston [ see also "Ogilvie's Boat"]. He learned this while a fisherman sixty years ago. It belongs to Peterhead and takes its' title from the staple diet of the fisher folk of the area. The line about "the harbour of refuge" in the last verse refers to the bay enclosed by a breakwater built from granite quarried by inmates of Peterhead prison, which was shelter for the ships of the First World War Grand Fleet caught between their anchorages in Scapa Flow and Rosyth."

Anne is correct about "wint" = "want".
