Simon,

Looking at tomorrow's weather forecast. I doubt whether you you will even get off the beach <img src="http://www.catsailor.com/forums/images/graemlins/ooo.gif" alt="" />

If you set up with the Mozzie on its side with mainsail attached and apply varying downhaul tensions you should be able to see what is happening at the mast head.

Hope it all works well.

Regards,

Peter
