[Rhodes22-list] Picture of heavy weather sail adjustments

[Steve]

Excellent analysis, Roger.  Right on all counts.  My
main does have a 2nd set of reef points but I wasn't
trying for maximun speed.  I didn't even bouther to
run the genona sheets inside the upper shrounds. Just
flaten it fairly good.   It was just a 25k wind day
and Marilyn & I were out having some fun.  So you had
to mention the fenders:-)No I did not bouther to stol
them away as I should have.  Beside, note I'm on the
lee side drinking a beer:-)  A man must have
priorties.  I did put Marilyn on the windard side:-) 
I get extra points for that:-) It was a fun sail that
day and some friends of mine that were anchored in
Goat Cove took the pictures.  They would not pull up
anchors and sail that day.  I think there excuse had
something to do with the wind; sounded lame to me:-)
