Mr Robertson, 61, the owner and skipper of the fishing boat Reul A Chuain, a twin-rigged prawn trawler out of Mallaig, died on 24 June 2021 after falling overboard while attempting to rescue a deckhand from the waters of the Sound of Rum.

A preliminary hearing is set for 5 June 2024 at Fort William Sheriff Court.

It is anticipated that the inquiry will consider any precautions which could reasonably have been taken and which might realistically have resulted in the death having been avoided and any defects in any system of working which contributed to the death or any accident resulting in the death.

Procurator fiscal Andy Shanks, who leads on death investigations for COPFS, said: “The death of Lachlan Robertson occurred while in the course of his employment and as such a fatal accident inquiry is mandatory.

“The lodging of the first notice enables FAI proceedings to commence under the direction of the sheriff.

“Mr Robertson’s family will continue to be kept informed of significant developments as court proceedings progress.”
