Thankyou for all the advise.
I might try some tell tales on my side stays as i am currently only using them on my fore stays, and I'll back my rig tension off a little, because I think this may have been to tight and there for stopping my mast from rotating.
I can't make it down to Palm Beach this week end because it is our last club race for the season but I'am hoping to get down that way soon. Maybe the Brass Monkey [when is that on and whoes going] Hay Will are you racing the Mozzie with a crew at the Brass monkey or are you on a mono.
