Fishermen are being warned of the dangers of using drugs while at sea following several deaths linked to the use of amphetamines.
In the last two years, 15% of fishing vessel accidents have involved drug abuse.
Micky Hill's son, Mike, was skipper of a scallop dredger when it capsized off Teignmouth, Devon. He died aged 22, along with Shane Hooper, 34 , who was found with amphetamines in his system.
Mr Hill says Mike would not have allowed Shane on board if he'd known he'd been using drugs.
