Tuning my Rigging

I have found my boat, she is a beauty.
The 37.5 Hunter i've been looking at, has everything but;
some of the main stays are loose, some are thight.
I need to tune the rigging before i set out to get her home to kemah.
I will motor most of the way, the ICW, but will want to sail a little in the open spaces.
I can tighten up the looser side stays for now.
Is there something i should know about doing this?
I would appreciate any input.
thanks my friends

It is easy to do it yourself with a Loos gauge.

Recent Hunters have been innovative with reducing their number of shrouds. I'm always struck with the similarity of a rigged sailboat to a bow with the arrow fully drawn. Our sailboats are subject to having the mast fired through our hulls or having our bow and stern raised by an over-tensioned rig. Traditional rigs, like mine, should have the uppers more tense than the lowers and, I've been advised, the foreward lowers more tense than the aft lowers. This should be achieved with port and starboard symmetry and a slight slacking of the leeward shrouds during a stiff point. With the variety and advancements in rigging, I would consult the tech support from the manufacturer.
Take care and joy, Aythya crew

Yeah, Like above. To do it right you need advice from whomever built the rig or someone who knows. No shroud be loose on any modern rig. Stays are a different matter entirely.

For the motor home, assuming nothing is actually broken, you might just wind the slackness out of what you think is causing the loosness - it may not be the loose wire but an opposing one.....look up the mast and see that she's straight within a inch or two. And then only sail in gentle stuff, no more than 10 degrees heel, until you really know what is going on.

Loos gauges are handy if you have some numbers, lacking numbers to adjust to they're pretty useless.
