Guys,
Thanks for your comments. The slides could be a bit dry but the sheave at the top of the mast was free a few weeks ago before we launched.
We did remove the halyards this year (and last) drawing strings in to aid replacement. I thought this would avoid any tangles inside the mast but perhaps not! I guess we can check if the halyards are tight by trying to pulling them up without he sail attached but if it's tight and we suspect internal friction, how do we untangle it with the mast up on the water?! However, the sail does drop when the halyard is released but not right down without a bit of help. I must confess that I was expecting a fully battened sail to drop more rapidly - perhaps we do have a problem within the mast....
Regards
