trimming the mainsail
I've read at sfsailing.com under Performance Sailing, chapter 6 that in heavy air (6.5 Reaaching and Running Trim) that they recommned "dump the vang to spill the leech when overpowered, and be prepared to dump the sheet to prevent a broach." I've also seen that advice in the Highlights of Scot's and Water. Most other places, like Kelly Gough's advice, is to tighten the vang, and when in doubt, tighten further. Is there a nuanced distinction that is not named here when we use one method versus the other, or are these differences of opinion? Thoughts anyone?
