The charity lifeboat at RNLI Kessock was launched after being called out by UK Coastguard to assist an incident at Friar’s Bridge on the River Ness.
The volunteer crew responded at 1.08am after concern was raised for a person at the bridge, but were stood down as the situation had been resolved.
The exercise however highlighted the impact of coronavirus on the crew’s procedures.
Previously, when the pager sounded, every available crew member would attend the station as quickly as possible and an operational crew would be selected.
New rules to safely observe social distancing, and to best protect the crew and any casualty, dictate that as soon as the required number present at the station a message is sent to the rest of the crew not to attend.
Stuart Gudgeon, Area Lifesaving Manager for the RNLI, said: “The new protocols have changed the way the volunteer lifeboat crew respond to a call to service in many ways.
“In addition to adhering as far as possible to social distancing measures, existing stringent hygiene controls have also been stepped up.
“I am delighted with how the Kessock crew performed today – it’s a tremendous reflection of the dedication of the whole crew during these very difficult times for all.”
