“I pray for them and their families as well as for the chaplains and volunteers of the Apostleship of the Sea,” the Pontiff said at the Sunday Angelus in St Peter’s Square, Vatican.
The Pope also made mention “of those who live in unworthy work situations at sea”.
Thousands of churches around the world marked Sea Sunday this year with Mass and prayers for seafarers, their families and those who support them.
It is estimated that a third of all seafarers and fishermen are Catholic, with a large number coming from countries such as India, the Philippines and Poland.
Meanwhile, in a Sea Sunday message, Cardinal Peter Turkson, Prefect of the Dicastery for Promoting Integral Human Development at the Vatican called for the protection of seafarers.
He highlighted the hardships that seafarers sometimes endure while working at sea including abandonment, inadequate personal time to rest and relax, and piracy.
