Hi Phil,
Ive been busy lately...next time your down at the boats can you check if my "bit of junk" is still floating
This is the procedure for reefing a junk rig(down to storm sail size, if you like)....
Make a cup of tea,
stand in the cockpit holding cup of tea in one hand,
with the other hand...uncleat halyard...
allow halyard to ease through your fingers, until the desired sail area remains...
re-cleat halyard...
resume drinking cup of tea...without having spilt a drop.
regards
Shaun
