May I make a couple of points for you all to think about,
Firstly, to me the idea of putting ballast into the boat to steady it is OK! but do remember that to counter this the strain on the rig becomes greater and the mast on the Wayfarer is not one of the stiffest ones on the market.
Second, maybe the righting lines could be of a strop type rather than just a single line that has a tendency too let you swing on the end of it.It is hard to stay on the under side of the gunwale at the best of times!
