My point about the J30 is 100% correct, no matter what you try to
twist it into.

Aparently you didn't pay much attention. There's no way a J30 set to cruise
for a week is going to outperform one that's ready to race. 4 people and all
the necessary gear, clothing, food etc. will not do as well as a 6 man race
crew and a few sailbags. I rebuted your post and so has half a dozen others.
