Milt My recollection is that the bridge clearance on the Erie Barge Canal is 22 feet if you Turn north to Oswego on Lake Ontario. If you continue to Buffalo on Lake Erie the clearance is ~15 feet depending on water level. http://www.nyscanals.gov/maps/index.html We saw a VERY large commercial cruise boat go thru the canal at Brewerton NY. Steve Burgis 36 Albin Summer Triangle. Specifically, what are the options for getting from the Atlantic seaboard to the St. Lawrence River? My draft is a solid 6 feet and my bridge clearance is 35 feet, but I'm prepared to remove the mast and carry it on deck if that's neceessary.
