If indeed what you've posted from Colcord is the type of shanty required you might also look for 'Little Sally Racket' which has numerous bawdy verses some original and some made up during the last 60 years. There must be a thread on this pattern somewhere.

Here's one of the more common verses.

Little Dolly Ducket, haul her away,
She washes in a bucket, haul her away,
She's a whore but doesn't look it, haul her away,
To me hauly hi ho, haul her away.
