gotta love youtube! this should help, enjoy
Actually, I'm not loving Google because I'm not finding the answers I'm looking for
- I understand that the vang keeps the boom from raising.
- I understand that tensioning it will flatten the sail.
- I understand that used in conjunction with the traveler is maintains the boom position, and therefore the sail twist, as the mail sail's angle is changed.
- I'm not clear on when, and by how much, the vang should be tightened or loosened.
- I don't understand how the vang's used differently when going up/down wind
- It seems to me, perhaps wrongly, that it's more important to make more frequent adjustments on small dingies than on keelboats. I'm I right? If so, why?
I've managed to find the Volvo videos that kicked off my curiousity. In this one he's adjusting the vang ("kicker") on the reach:
And here he's releasing the cunningham and the vang as he rounds the marks:
I'd really like to understand what's going on.
