O.N. 70-002 at Kirkwall - At 10.37 a.m. on 23rd September, 1968, the coastguard told the staff coxswain that a lobster boat had broken down half a mile north east of Gault buoy.

The 1RB carried aboard the life-boat Grace Patterson Ritchie was launched at 10.55. It was shortly before high water. She came up with the lobster boat Ewing McGruer, with a crew of two, and stood by until the arrival of the life-boat at 11.24. The lobster boat was then taken in tow to Kirkwall, and the life-boat returned to her moorings at 12.10 p.m..
