North Sails Webinar - Asymmetric Trim 

After one year Likes arrived only to 330. This deserves much more than that.

I think easing the outhaul when turning down wind is best practice just like tightening the vang. I think some teams have a perception that it is not worth enough on short W-L courses to always take the time.

@@danstanford3071 I agree completely, and I even have the outhaul on a winch, but look at the black stripes on the boom, their outhaul is tight as a drum.

Tack line down to the knot on the pole, very little play in the sheet since the wind is forward and no rotation of the spinnaker.

...or do you use it exclusively for hoisting and dousing?

Andrew Parkes thanks for your answer. Taking from it too that you probably don’t use the halyard for trim (likewise to main and head sail) but solely for hoisting/dropping the Gennaker.

Keep in mind that there is more wind higher off the water, and the closer the head of the sail is to the mast, the steadier it will fly. So keep the halyard fully hoisted, and ease the tack line if you want the sail to fly higher.
