O God, Who brought our fathers through the Red Sea and carried them safely through the deep as they sang praises of Thy name, we humbly beseech Thee to guard Thy servants aboard ship, and having repelled all adversities, bring them to the desired port after a calm voyage. Through our Lord, Jesus Christ, Thy Son, Who livest and reigneth with Thee in the unity of the Holy Ghost, world without end. Amen.
(This is the prayer used by Cunard Lines back in the good old days. It is wood-burned into my great uncle’s sea chest from his service as a 12-year-old cabin boy.)
