Clearly, the largest sail area can be achieved by completely
filling in that triangle... or by thinking "outside the box"
and ignoring the artificial limit imposed by the backstay.
Some boats have sails that overlap the backstay, other boats
don't have a backstay at all.


Sorry, I should have specified that going outside the defined area was
not permited for this excercise.



Yep. One of the consequences of being able to make sails
with higher roach than before is that more classes are
defining a mid-girth measurement for all sails.

BUT, the overall area of the sail is LESS!


Did you confirm this with a licensed rocket surgeon?


Indeed, Dr. Who no less, he offered to put a new black band on Bob's
boat with his sonic screwdriver!


Now why would you not want a sail that hoists to the black band?


A DUCK!!
