confession at sea

Any priest making a sea voyage is empowered to administer the Sacrament of Penance provided he has received sacramental jurisdiction from his own Ordinary or from the Ordinary of the port of embarkation or from the Ordinary of any port touched on during the voyage. Such a priest can validly and licitly impart sacramental absolution to his fellow-voyagers and to those who for any reason visit the ship at some port; moreover, in case he goes on shore for a brief visit (not more than three days) he can hear the confessions of persons who ask him to do so, and can even absolve from cases reserved to the Ordinary of the place.
