The Tug Boats ‘Shackleton’ and ‘Beaufort’, are named after two remarkable patrons of exploration. Ernest Shackleton, born in Athy Co. Kildare, was a fearless explorer whose legacy as the world’s greatest exploration leader will live on as an inspiration to pioneers for centuries to come. Sir Francis Beaufort, who hailed from Navan, was a tireless innovator who created the scale of measurement for wind force which is now world-renowned, and is used by the 15,000 vessel arrival and departures in Dublin Port every year.
