Royal Mail ShipSince the 1800s, when the designation was first used, there have been approximately 200 Royal Mail Ships. Because these ships carried mail, they were contracted to be on time. They faced stiff financial penalties for delays. The designation  became a mark of excellence.

The only steam-powered Royal Mail Ship in the world

Of the four remaining vessels only one is powered by steam – RMS Segwun. She is the only steam-driven Royal Mail Ship in the world.

Although Segwun no longer carries mail from port to port in Muskoka, mail dropped in the onboard mail box will be franked RMS Segwun. The cards and letters will be forwarded to the addresses inscribed.
