I have a couple of questions if you guys or gals don't mind. I am completely new to laser sailing. My first question is about the vang well both question are. But the first one is what do they mean when they saw adjust the sail for 30 degrees of twist. I know they mean in medium to heavy winds. I kind of think what it means. the top of the leach is twisted off 30 degrees from the boom but like how many inches off of boom or what. Its a pretty tight vang right. just seeing what other people think about that. My other question is vang in medium or heavy wind. What is a good starting point for the vang setting. I have heard one person say easy the vang all the way off and gradually make it tighter. Less vang is better going downwind than too much vang on. Any advice for a good vang setting in medium conditions. Maybe setting the vang where the top of the leech flicks fore and aft about 1 foot. Any ideas would be appreciated.
