Lifeboat crews were called out after two people became stranded by a rising tide.
The team from Stromness RNLI received a page at around 9.35am regarding the two people, one of who was blind, stuck at the Brough of Birsay.
The lifeboat left the harbour shortly after and headed out close to the Black Craig, heading north. Conditions were choppy and the lifeboat arrived at the Brough at 10.25am.
The seas from the SW were breaking heavily on the SW shore so the lifeboat approached the Brough from the North.
The conditions were evaluated and after discussion with the coastguard they were considered too dangerous for the small Y boat to bring the two people back who were in no immediate danger.
Instead two crew went through breaking surf over rocks in the Y boat to the shore and spoke with the people who were happy to remain on the Brough and wait for low water. The crew left food and water with them and returned in the Y boat to the lifeboat.
The crew headed for home at 1110 into a lumpy SW swell at reduced speed.
The lifeboat returned to Stromness Harbour at 12.10pm and was then re-fuelled.
A RNLI spokesman said: “A big thanks to the folk ashore who covered for the volunteer crew members today in their ‘day jobs’, allowing them to man the lifeboat.”
