Hello,
The leech of my in mast furling mainsail when going upwind “vibrates” (sorry for the poor terminology). I have tried lots of actions to eliminate it but with no success. I tried tensioning more or less the foot of the sail with the outhaul as well as the luff tension with the halyard, I tried sheet in more or less and also rising up a little the boom. Nothing worked. I must mention however that this thin line running along the leech (don’t know the name) is broken and I realise that could probably help. Is it a matter of bad trimming or is my mainsail loose and is asking me for a change? Any ideas?
Thanks
