The 26-metre, Inverness-registered trawler was stuck fast and was listing when the Severn-class all-weather lifeboat arrived on scene around 1.40am.
Lerwick Port Authority vessels Knab and Kebister, and the fishing vessel Faithlie, also arrived soon after to assist.
After assessing the damage, attempts by the lifeboat crew to tow the vessel off the rocks on a falling tide were unsuccessful, with two tow lines on the lifeboat snapped in the effort. The other vessels on scene were also unable to free the trawler from the rock.
The nine crew members were taken off the stricken vessel by the lifeboat around 4am and safely returned to Lerwick Harbour, with only minor injuries, and into the care of the ambulance service.
Weather conditions were calm with light winds and a moderate sea swell, with the air temperature just above freezing.
Around 12 hours later, the lifeboat returned to the scene to assist with another attempt to refloat the vessel at high tide, just before 1pm on Saturday.
The Knab and Kebister were successful in pulling the vessel off the rocks on Saturday afternoon and took the vessel under tow into Lerwick Harbour, accompanied by Lerwick lifeboat.
Lerwick RNLI’s deputy coxswain Tommy Goudie said: “The outcome of this grounding could have been a lot worse. Thanks to fair weather and the combined efforts of ourselves and Lerwick Port Authority vessels, the fishing crew are safe, and the vessel is now safely in harbour.
“The crew did the right thing by contacting the coastguard as soon as they knew they needed help. They were wearing survival suits and life jackets and deployed their life raft in case it became necessary. Our crew are always ready to respond and we’re pleased to be able to assist.”
