[C320-list] downwind cruising sail ?

[Robert E. Sloat]

Irv-I have an asymmetric with a sock and the ATN collar and from day one
have used two sheets and have no problem gybing.  The UK folks built it for 
me using C320 spec. measurements and
hard copy and CD ROM instructions were included.  The instructions were very 
helpful on operating the thing.  They
don't mention a single sheet system and all their instructions are for two 
sheet
set ups.

Check out the various sail makers web sites for instructions if you have not
done so already.  UK has some on-line videos covering asymmetric gybing if
you register at their site.

If you are having trouble launching, per UK, the key to launch and take down 
is to let the main out to the
shrouds to shadow the spinnaker while on 120 or more apparent.  To prevent
wrap arounds on launch make sure the spinnaker clew is back near the
shrouds. Further on Warren's comments, to help get the spinnaker in front of
the forestay on a gybe, the main is pulled to the center pre gybe to allow
the wind to blow the spinnaker forward of the forestay.  Then you haul in
the new sheet after releasing the former working one.This is all what UK
recommends and has worked for me from first try.

A drill we use on launch or take down, is that the person at the helm always
knows which way to steer if in doubt or things get confusing.  On a
starboard tack launch or take down, if in doubt turn right and for port its
turn left.  That way you will never accidentally gybe on launch or take
down.  We use the same thing when sailing more than 140 apparent to also
prevent accidental gybes.  Response to major wind shifts override this.

Good luck on a first perfect launch, gybe and take down.
