Welcome.
A DS is relatively stable, but note the term relatively.
You will need to balance it from moderate conditions on, mainly to keep the boat nice and flat so it sails well. At some point, you'll need to luff up, ease sheets or eventually reef to keep heeling from gusts or stronger winds in check. The transitions tend to be smooth, and compared to smaller, lighter centerboard boats they can feel "deliberate", giving you usually enough time to react.
Unlike a keelboat, you don't want to sail the DS heeled, except temporarily as you regain control from a gust, or later, when experienced, you might like to ride on that knife's edge of vanishing stability. But until you get the hang of the difference, try to keep the gusts to well under 15 as you figure things out.
Sailing areas that have obstructions like bluffs and tall buildings can have eddies that produce large wind shifts. The reaction to these can be quite dramatic and I'd advise you to avoid them. That said, the DS, more often than not, will simply round up and twist out from under a gust if overpowered.
But, all that can wait until you are on the water (if I haven't scared you off
).
Good luck with sorting sail and rigging. Patiently digging around in the older posts should uncover a trove of useful detail -- however, I'd advise against making too many modifications prior to your first season: you will have a better idea what works for you, if you try the existing setup. As long as it is solid, that is.
Well, we broke a jib track on the maiden voyage, so that's par for the course I guess.
