In Plymouth, the crew respond to a mayday call - the highest level of emergency at sea - for a scuba diver who has lost consciousness during a 30-metre dive to a shipwreck. When the lifeboat crews respond to a medical emergency, they know that every second could make the difference between life and death.

Along the south coast, both of Hayling Island鈥檚 lifeboats are launched to search for two jet skiers who have been reported missing - with no phone signal and the light fading rapidly. In Brighton, a member of the public has called the coastguard after watching a yacht with a torn mainsail struggling to make any headway. And in Llandudno, north Wales, the crew are tasked after reports of a dog - and its owner - struggling in the water.
