Following a very light air day it occurred to me that a system to fully sheet out the main sail would be jolly useful but I wonder if the rules allow such a thing.  Rule C.5.4 (c) States:- Except where achieved by mechanical systems, automated control of rig and/or sails and automated steering and/or navigation are prohibited.  Would a shock cord system that kept the main sheet under tension be allowed I wonder?

Cheers

I wouldn't think there is a problem with putting some elastic on the main but I expect to be shot down

Tried it on a Marblehead, in very light airs it  worked too efficiently and the boat would suddenly sail backwards when the elastic was stronger than the wind

Oh well it was a good idea while it lasted. My ISIS goes from 10th in the fleet to 3rd in light airs so I can’t complain! Now perhaps if I oil the gooseneck .......
