Hi Rick,

For years I felt that the mainsail should be trimmed first, just as you have said.

I was lucky enough to crew aboard a sailboat that always won races and watched as the jib was always rough trimmed prior to the main. After adjusting the main, the crew touched up the jib controls. I asked why and the answer was always about the relative position and interaction of the two sails. The main is in the shadow or wash of the larger forwardmost sail.

I tried the process on my Rhodes 22 and was very surprised that I was able to change course faster and get back to speed quicker by paying careful attention to sail shape and deployment of the genoa before I fiddled with the main. One of the most important considerations was the angle of the genoa to the furler. It should be near 90 degrees and result in a very well defined curvature. In the past, I had always set the jib sheets much too tightly.

I quickly looked for an article as a reference and found this one:
http://sailingmagazine.net/article-17-sail-trim-101.html
which starts with:

"When discussing overall sail trim, it makes sense to start with the headsail for two important reasons:
    The jib directs airflow over the mainsail.
    The jib itself creates lift and provides a portion of the boat's forward momentum."

I am not saying that you must set the genny first, but please give it a try. You might be surprised.

I’d rather be sailing :~)

Hi Mike,

I respectfully take issue with your suggestion to set the genoa sail before the main.

My training to sail a cutter rig was to first set the inner or staysail first, then the outer or yankee sail.  The logic is that the accelerated airflow over the staysail lifting surface is the greater force exerting more influence on the overlapping yankee than the other way around.

Especially with the 175 genny on the R22, the main will have considerable influence on the curvature of the overlapping genny.  So I always *first set the main*, get it to pull as hard as I can per the knot meter, then set the genny leach curvature to match the main leach curvature.
