Your traveller is only effective in helping control twist if the boom is still above it. Once you're going downwind and the sheet's let off there's very little downward component to the mainsheet pull. This is where a vang is helpful, it can be used to limit boom lift, provide leech tension and limit/manage twist.

If I had to pick just one, it would be the vang. A powerful easy-to-use vang is like having an infinitely wide traveler.

As an example, look at a competitive Laser dinghy.. a pretty mediocre traveler arrangement, but you'll see a high power vang.

Thanks for the advice. Cripe there's so much to learn. I'm taking it all in as fast as I can. There's a huge learning curve just with the terminology :/

Re: What size boom vang

Faster: I hadn't thought about that kind of jybe, that's why I come back here and learn more. I can see how a vang would prevent that, but it's pretty secondary to it's normal purpose or learning how to avoid accidental jybes.

True, but such a gybe is almost more likely to occur early in your sailing learning curve rather than later.. something as simple as the vang can prevent that 'unnecessary' occurrence. And it's most likely and most potentially damaging during a DDW - mainsheet fully eased situation.

If a good vang isn't in the budget, a simple fixed strop will perform that function alone...
