Robert Courts MP, Minister for Aviation, Maritime and Security, offers some potentially lifesaving advice for those heading to the coast this summer.
Look after yourself and others at the coast: never use inflatables in the sea and visit a lifeguarded beach if you can. If you get in trouble in the water: Float to Live.
Remember, if you find yourself in trouble, call 999 Coastguard.
