I'm trying to find information about (what I take to be) a gaff-rigged yawl photographed on Lake Ontario. The photo is dated 1924 and is thought to have been taken from the pier at Oakville, Ontario. The owner of the yacht was a member of the Chisholm family, which figures prominently in the history of Oakville. A length of over 100' is given, but this is not authoritative. To me this looks more like a boat for racing rather than cruising. Any help gratefully appreciated.
