Re: Aftstay and forestay sag
Faith, if you are happy with the way the boat sails. Then you just need to tighten up the rigging.
If there is plenty of adjustment in the turnbuckles, just take up a few turns on each of them.
Some headstays are fixed length, but most of them will have a turnbuckle inside that furler. It may be a bit troublesome, but it's usually not too difficult to access the turnbuckle. And it's not a bad idea to get familiar with it and to make sure all the screws turn and maybe lube it if it's applicable.
You will have to drop the sail of course.
When I tune a rig, I will usually set the headstay length and then tune the rest of the rig.
If you have never done that kind of thing, it might be a good idea to work with a rigger for the first time so that you will be able to take care of it yourself in the future.
What kind of furler do you have?
