RMS Segwun is the oldest operating steam driven vessel in North America, built in 1887 as Nipissing to cruise the Muskoka Lakes in the Muskoka, Ontario, Canada, a resort area with many lakes and rivers. Early in the 20th century, Muskoka was poorly served by roads. Vacationers were transported to lodges, or private cottages, via a fleet of steamships. Segwun is one of only three ships in the world still carrying the status of Royal Mail Ship. Ports of call included Gravenhurst, Bracebridge, Beaumaris, Port Sandfield, Port Carling and Bala.
