Ah now it makes perfect sense Harry sorry I didn't read your post properly, we only have a couple of drifters here a year, the rest of the time its well over 10 when the seabreeze comes in and we race triangles (I couldn't live without a reach). I accidently eased my jib luff tension once in a bit of wind and couldnt pull it back on even with the double block no matter where I pointed.
