RMS Segwun
passenger steamship in Canada

RMS Segwun is the oldest operating steam driven vessel in North America, built in 1887 as Nipissing to cruise 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 the oldest of only three ships in the world still carrying the status of Royal Mail Ship, and the only steamer.
Ports of call included Gravenhurst, Bracebridge, Beaumaris, Port Sandfield, Port Carling and Bala.
History
Construction
In the 1920s the Muskoka Lakes saw strong growth in tourism as the Canadian economy recovered from the trauma of World War I. By 1924 the Muskoka Lakes Navigation Company found that the six steamers then serving the lakes were growing inadequate to the task and looked to add to their fleet. Rather than commission an entirely new boat, management decided to convert the decommissioned SS Nipissing from a paddle-wheeler to a twin propeller passenger steamer. Nipissing's wrought iron hull was built on the Clyde in 1887 and was in service on the lakes from 1887 through 1915. When Segwun was rebuilt on the hull of the second SS Nipissing she was also converted from a side paddle wheel steamer with a walking beam engine into the current two counter-rotating propellers.
The conversion was performed at the Navigation Company's yard in Gravenhurst, Ontario during the fall and winter of 1924–5, at which time the bulk of Nipissing's machinery was removed, including her engines.

Why this record matters
“RMS Segwun” is worth following because a concise public description often conceals a longer documentary argument. Here, Segwun, passenger and steamship provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 24, 2026. The linked authority identifier is Q7277104. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1887, 1924 and 1915.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
