Breeze is up the vang needs to come on.
Vang on boom down- good work
Breeze has died. Need more twist. Vang should be off and halyard eased more. Joli looks to have it right.
leech still too tight. Need more twist to have some part of the sail working with the swirling wind
Last week I aimed the GoPro higher up into the mainsail to get a full picture of the leech twist and the footage is instructive. As the breeze freshens the mainsail shape responds well to extra vang tension but, and it is an important but, the vang needs to be released very promptly as the breeze lightens. In the really light patches the main halyard also needs to be eased so that the battens are not compressed hooking the leech to windward.
There are some good photos on the leg back from Cockatoo Island back into Humbug and as we approach Onions Point the photos show we have the straightest leech while our competitors have already eased their gear and perhaps excessively so. If we can all find the right twist there might be less shout. Apologies to Chubby Checker and to the young who never heard of the song Twist and Shout.
