Following a breakdown of on 28 July 2015, "Isle of Lewis" took over on the Uig Triangle, allowing "Hebrides" to sail to Stornoway for repairs to her propulsion unit. The larger vessel took this unusual duty in her stride despite having to work by the available tide at Uig owing to her deeper draught. "Hebrides" was able to return to service early on 30 July, although "Isle of Lewis" remained on the triangle for the remainder of the day to clear any backlog of traffic, and returned to Stornoway following an extra sailing from Lochmaddy to Uig.
