Most of us probably never give much thought to seafarers. They can seem remote from our daily lives. Yet they play a critical role. Without the world’s 1.5 million mariners we wouldn’t have many of the things we take for granted. Cars, computers, clothes, fruit, vegetables: these are just some of the items that are transported to Britain by ships.

This week we mark Sea Sunday when parishes are asked to support the Apostleship of the Sea (AoS), the Catholic Church’s maritime agency. Its chaplains and teams of volunteer ship visitors offer practical help and pastoral care to seafarers, either in ports or on cruise ships.
