Clever!
BTW, I think I spotted a mechanical joint. Is it just a spare or you actually use it?
thanks, indeed mechanical joint, yes I use it all the time, bought 3 plates, so the mast base stays in the right position on each board.
Think I bought it something like 20 years ago on the gold coast (can't remember the shop name, was somewhere around sporty's warehouse)
So convenient and safe ! I carry a unijoint spare in my vest, "just in case"
