Ok Doug,

I' ll give it a try

Since the Vang; Solid or Rope, What ever, has been kicked around as a
Hoisting Device, which it isn't let's talk about what it is for.

Well, it's main function is to pull the boom down. While the boom is over
the travellor, the mainsheet can be used to control the height of the boom.
As the boom moves outboard of the travellor, the sail will lift the boom
unless the vang is used.

However, my boat doesn't have a dedicated topping lift, so I also use it to
keep the boom up as we come into our berth.


Why is it necessary? When do you use vang pressure? To do what? If it's
good sometimes, why not all the time?

Whenever the boom is not over the travellor, the vang can be used to control
sail twist. I suspect that many sailors use it even when the boom is over
the travellor. In this case, the sheet can be eased instead of lowering
the travellor.



How much tension should be put on a Vang? Can a strong Deck Ape over
apply tension by hand?





Let's talk about it.

You first Doug. It is a Racers gimmick. Tell us why?

It isn't a gimmick at all. Cruisers us the vang when going downwind to
reduce "death rolling".

Donal
