At 10.27 p.m. on 22nd October, 1966, news was received that the cabin cruiser Alcidan was overdue on a passage from Weymouth and that the Norwegian tanker Maakfjell had taken three men off ayacht they had taken in tow. They were eleven and a half miles off Anvil point.

The life-boat R.L.P. was launched at 10.59 in a moderate to fresh northerly wind and a corresponding sea. She met the Maakfjell south of Anvil point, took off the three survivors and took over the tow of the yacht Sea Venture HI. An R/T message was received from the motor yacht Espardarte requesting assistance. The lifeboat found the Espardarte and, with the Sea Venture III in tow, escorted her to an anchorage in Swanage bay. When both boats were safely moored, the survivors from the Sea Venture ///were landed.The R.L.P left at 2.10 a.m. on 22nd October and proceeded to Studland bay to start her search for the Alcidan. She searched the coast southwards and to the west as far as Kimmeridge Ledges without success, and then returned to the slipway at 6.35 to wait for daylight. The crew reassembled at 8 o'clock and stood by while the honorary secretary telephoned the owner to inquire whether the Alcidan had arrived at Wareham. The owner telephoned at 9 o'clock to say that she had arrived safely having been aground off Giggers island at the mouth of the river Frome throughout the night. This was confirmed by the coastguard, and the life-boat was rehoused at 9.48..
