I pulled the temporary thwarts out and moved the canoe off the strongback over the weekend. Probably a bit of a mistake on the thwarts, as the keel stinger hogged some when I did it. I'm attempting to correct that. I fashioned a long "plug" from the same stringer material that tapers thin on either end and I lashed it below the keel line. It fills the void created by the bow and stern sloping down and the keel line is back to being straight. I also plan to put in a slightly wider thwart/mast step to hold the wales out a little wider, in hopes it pulls the ends back up some.
