No worris on the assist, you're welcome. As to further thoughts; tuning the rig's a good first step. Particularly as movement in spars & rigging
is where most of the wear & tear on things comes from. And sailing in light air tends to do more damage to things in the long run, than does heavy weather
. Especially if things are loose.
It shouldn't hurt to tighten the backstay, prior to getting things tuned. And DIY
tuning is a good thing to learn, as it's not difficult to do. Plus the required tools aren't outrageous in cost. So you'll recoup the funds, & then some, over time.
And it's rare (as in almost never) that you go up the rig, & don't see something which could use some TLC. And checking everything up there's a good thing to do before & after any long, or arduous passage
As far as tuning, this is one of the books
which I own https://www.amazon.com/Sail-Rig-Tuni...p_s_cp_24_WNXH
And no, it's not exactly the latest thing, but it's pretty good.
Also, sailmaker's, & their websites sometimes have useful tuning info. And you might peruse this site as tool, it's got loads of info on boat
Hope I'm not telling you too much of what you already know
And good luck!
