[C320-list] Shorten Upper spreaders for 155% genoa trim?

[resloat]

Agree-Work on the sail and before that play with halyard tension to move the 
draft around.

The sailmaker would have to know about the spreader change to tweek to the 
foresail design.  Shortening would also change mast geometry affecting 
loading and the need to probably shorten the Cs.  Cutting either end of the 
spreaders would also probably require some real engineering modifying the 
attachment design at the mast and new spreader tips.  There is taper on 
these things.  I have a half empty glass on this.

It would be far safer to have your sail recut ...probaly cheaper in
the long run as well.
