I'd go with the ceremony BW listed from 48North
And Joe Thomas...I think the ring/coin under the mast is what old time sailors did just in case the boat went down then at least they would have money to pay the "toll" to get through thegates of heaven .Plus I found a Paryer I Really like for Boats and the people who sail them...Here it is...(I think its Gaelic or something) O Thou who pervadest the heights, Imprint on us Thy gracious blessing, Carry us over the surface of the sea, Carry us safely to a haven of peace, Bless our boatmen and our boat, Bless our anchors and our oars, Each stay and halyard and traveller. I myself will sit down at the helm, It is God's own Son who will give me guidance, As He gave to Columba the mild What time he set stay to sails.
