Wooden mast - gaff rigged. Can anyone give me a rule of thumb on how much tension to have in the shrouds. The boat has come back from having her mast raised and 1 shroud is "slack" I can't get the boat back to the yard and and there are no riggers round here . Thanks

Although I have a wooden boat she's bermudian rigged with an alloy mast.
However, I would have thought the same basic rules apply.
I centre and tension everything then go for a gentle sail.
Point upwind and as she heels the lee shrouds unload and the windward shrouds tighten.
I adjust the lee shrouds so they don't unload completely and avoid shockloads / spreaders moving / detaching.
Repeat process with a bit more wind to make sure !!!
I also have fore+aft lowers and set these after the cap shrouds to manage mast bend.

I've also noted values from a very basic tension meter to speed up the initial set up.

No doubt there are more technical approaches but it works for me. hope it helps

...repeat for both tacks, making sure that the mast remains upright and 'in column'.
