I was looking at a book on the West Country the other day and came across these two, either of which may be what you're looking for.
An apocryphal version of a Cornish child's prayer:
"God bless Vaather 'n' Mawther, 'n' zend a ship t'shore vore mornin", and the prayer that Parson Troutbeck used "Dear God, we pray not that wrecks should happen, but that if it be Thy will they do, we pray Thee let them be to the benefit of Thy poor people of Scilly."
