[Rhodes22-list] Fred's Sails

[Steve]

You got that right; Roger.  Beside you know as well as
I do that the winner is the one with the most tricks
up his sleave.  

When racing, you don't have time to readjust your
sheet & adjusting the lead forward while on the same
tack is almost imposible.  But you can run a secondary
in a minute notice when the wind call for it.
Steve

PS - I bet our old boats can take these new
diamondboard:-)
