If you and your Seawind are ever near the Connecticut River, I'd welcome a chance to check out your boat. I own Patience, ASW1 #105 and we live in Old Saybrook, CT. I've tackled similar projects to you (except the replacing the standing rigging and sails).
Cockerline123 - I agree with Jeff H that the strong point of this boat is its simplicity and the best improvements are those that enhance the existing systems without adding a lot of complexity. Of course, I don't always listen to my own advice - I'd like to install a water wash down pump to replace the "canvas bucket" system for cleaning the anchor and rode. And a wifi system would be nice...
I recently built a website to catalog my boat projects and you can see pictures of Patience there:
