In Ireland, the Castletownbere crew race to rescue a lone yachtsman who has lost his mast and is drifting powerless in 10-metre waves, 45 miles out to sea. In Minehead a woman on a clifftop walk has gone missing, and after 17 hours the crew are called to search the shoreline. And for an injured horse rider on a remote beach, the Porthcawl crew are the only way to emergency medical help.
