The UK Maritime and Coastguard Agency (MCA) said that one of its members at Hayling Island observed a flashing light off the coast that seemed to be sending an SOS. He responded by flashing the lights of the control tower. The Coastguardsman alerted the Marine Rescue Coordination Centre, which requested the launch of an RNLI lifeboat. The rescue was successfully completed. It turns out the man had transferred all of his safety equipment from his 28-foot fishing boat to a newly acquired vessel. He was running his old boat a short distance down the coast when it grounded. The only safety equipment he had on board was his flashlight.
