On the capsize issue, it seems to me that this should be addressed the same way

Differentiate by heeling moments - ie sail area and wind strength.

Rather than trying to say that a particular layout is "safe", determine the
allowable wind strength for different sail arrangements.

Top sails, sky sails and lighter kites for lighter conditions and strip down
for higher (Or Rated) winds.

That actually doesn't work. The real issue, which has never been
addressed properly by regulation, is unexpected wind increases and the
rate of vessel response. Having the proper sail set for a specific
wind velocity isn't going to make you safe if there is a squall
bearing down that you are not prepared for. Current USCG regulations
for sailing passenger vessels will let you have a vessel that can be
capsized by that squall by reducing the sail plan to an unusably small
area for normal conditions. At the same time, the will prevent the
certification, in many cases, of a vessel that would be knocked down
by the squall but recover without flooding. It's crazy. Be sure to
read the last section of the stability site.


I think I get your point now.

FAR 25, which covers load factors and gust loading in commercial aircraft
doesn't have to deal with flooding and the resultant stability changes!
