Good point. No, I'm not at all positive that it was the headstay. It appeared to be (as you say) the leach of the headsail. We did just a small amount of experimenting with moving the cars for the jib sheets
, and I may need to do this further in similar wind
conditions and see if it will alleviate this. After docking
I grasped the roller furler
and "wiggled" it. I was impressed with its mass. The surveyor
, last week found the rigging
to be in good shape. I posted because of what the experienced sailor said ("hmm, I wonder if your headstay needs tensioning"). Thanks, for your input.
