[Public-list] #2

[John Boor]

It is interesting that you use a number for different sail size.  For me I
have no idea how big (small) your #2 is, I prefer to use a percentage of
"J" to determine headsail size  these are my sails 170% light air genoa, 
150% furling working sail, 100% heavy weather jib.
