Congratulations and welcome to the Lifestyle. I still remember how all consuming sailing was when I was first learing my way around a boat. Funny, 30 years later and it hasn't lost the thrill.
FWIW, I wouldn't worry too much about mumble-jumble like capsize ratios, you will have to go very far, and push the limits well beyond what 99% of Sailnet members ever do in their boating, to have to worry about basic stablity..heavens knows, don't discuss stuff like that with your wife!
I'm thrilled if I can bury the rail on my CS 36T once or twice a year.
Certified...in several regards...
