We took our IP-37 across the Waterway in 2006. We stayed at the Glades, Roland Martins in Clewiston, and then in Stuart. The Railroad bridge is supposed to be 49'. I think there is a FREE dock
in Labelle, but didn't look good when we were there. Also a FREE dock
in Moore Haven. (I'm basing this on memory) The Waterway is pretty much straight and narrow. It's possible, I suppose, to pull over to one side and put 2 anchors out fore and aft and be OK.
