Mezeron and Ramsey will bid farewell to the haulage firm’s former flagship later today.
Silver River will depart Ramsey for the final time this afternoon.
Having served the company for almost four decades, the Silver River was replaced as flagship after the arrival of the Snaefell River late last year.
Mezeron MD Steve Walton said: “This vessel has faithfully served the island through many challenging times, and the crew and team have always gone above and beyond to ensure the islands needs are met.
“After many years of dedicated service, its time to bid farewell to the old lady.”
Silver River is due to leave Ramsey for the final time at 2pm.
