Life-boat 70-002, Lerwick, Shetlands - At 12.9 p.m. on loth July, 1966, a local visitor informed the coxswain that there was a dinghy apparently in difficulties off the harbour. Using his binoculars the coxswain saw that the dinghy was dismasted. The life-boat Grace Paterson Ritchie launched her small IRB at 12.11 in a gentle south by easterly wind and a slight sea. It was four and a half hours before high water. The IRB towed the dinghy with her two occupants back to their slipway at Lerwick. She returned to the life-boat at 12.30..
