Oh your'e a brave man G watching it all on the telly. I could watch someone elses

Good Luck
Had my carpel tunnels done a few years back, laid out mon a cross shaped bed ( Crucifiction style) with anaesthetic in both hands. Couldnt resist watching what was going on which seemed to irritate the doc. So he demonstrated the function of the wrist to me in the same way we used to play with chicken legs in my childhood. Scissors under the opened up tendons and he could make my fingers and hand do all sorts of gestures without me moving a muscle. Weird.
To the OP. What sort of sailing by the way?
