Mike: Looks like a log driving Bateaux -close relative to a drift boat. Here in Maine these were in common use driving sawlogs down the rivers- such as the Penobscott . The mills provided lumber for the north east coast. I might take days to get down the rivers and the Bateaux hauled supplies for the camps. Log jams were a problem and had to be "pulled apart" by guys running along the jams with peavies and pike poles. These guys had guts and today they would drive OSHA inspectors nuts.
Good picture- buy it
