Just to clarify the propulsion description . The Griffon only had a single screw set up with one 10 cylinder Fairbanks Morse Main Engine through a gearbox .

I remember seeing this vessel for the first time, i was on CSL package freighter Kenora in Oct. 1955, the ship I was on was built in 1907, and the Griffon brand new in 1955, it made an odd looking pair, with emphases on the Griffon being a modern looking vessel and our old clunker that I was sailing on, 51 years ago. I saw her for the last time in lock 4 Beauharnouis as I was waiting for the Ralph Misener, Griffon, by this time Telchac, was leaving the lakes for the last time in 1989.still a good looking boat, only longer.
