boats are boats, some built better, some designed better. All are compromises. None will survive the all out fury of mother nature at one time or another. Doesn't mean they are bad boats. Some of the best built/designed boats have failed in spectacular ways, with very little weather to contend with, so some of it is arrogance of the men who sail the. (re: racing boats that crack in half, masts snapping, etc)
A lot of it, when you look at those who sail the world, is luck.
