Charlie Martell used the phone to contact Falmouth Coastguard in the UK to summon help after his boat capsized several times when it was hit by winds of up to 50 knots and waves of more than 50ft (15.25m). The double Guinness World Record holder was attempting to set three new world records and raise money for charity in a 4,500 mile (7,242 km) solo crossing of the North Pacific Ocean. Falmouth Coastguard passed on details of his boat Blossom, which was damaged during tropical storm Mawar, to the Japanese Coastguard which then co-ordinated the rescue. Charlie, a Territorial Army Lieutenant and former Royal Engineer, had been at sea for 36 days when the storm damaged one of his boat's main bulkheads.
