At 0443 on 18 July 2018, the Netherlands registered general cargo vessel Priscilla ran aground on Pentland Skerries. When approaching Pentland Firth, Priscilla was set to the south of its planned track but this was not observed because the officer of the watch did not monitor the vessel’s progress for about 2 hours; instead, he sat in the bridge chair and watched videos. It is also possible that the officer of the watch fell asleep periodically.
