[C320-list] In Mast Furling (Free advice)

Mon Nov 27 17:07:52 PST 2006

>From my experience, Orlando's suggestion is about right when running deep
down wind. We typically ease the boom out as far as we can and use the vang
to allow only enough twist to keep the top of the sail about 90 degrees to
the wind.  If the top of the sail twists beyond 90 degrees to the wind (as
seen at the top of the mast), then you've allowed too much twist and are
spilling your wind, so add more vang.

Very little tension, let the boom rise..it's one of those 'each boat might
be a bit different'...you need to experiment a bit..

What your looking for is a bit of twist at the top of the mainsail, I know
conventional wisdom is to have it flat but try it, you'll notice a huge
difference in boat speed.

Interesting tip Orlando...I've always done this out of habit...when you say
'don't tighten' and loosen a bit, do you mean leave it completely loose, or
have some tension? I will give this a try--this spring :)
