Among other things, your message convinced me I should make a tether for myself. I thought I remembered a message a few years ago where you explained how to make one, and where you attach it on older boards, but I can't find it with a search for "tether" in the forums. (I have my 01 Start, and an 02 Start, and I don't think either have built-in tether gadgets.)
My memory is that your old message said:
1) Build the tether to be about 20 feet total, with a few feet of shock cord ("bungee") to reduce the sudden accelerations.
2) Attach the cord to the mast *of both boards*. I think the argument was that this attachment is best for limiting the "turning effect" of having a line on the board.
Is this right?
