Vibration from Roller Furling

Hi, Just purchased my Sabre 30 and it has a Harken roller furling. During the initial sail while sailing close hauled into approximately 20 knot winds, a bit of vibration came from the forestay/roller furling. Not a huge amount but definitely noticeable. As soon as we fell off the wind slightly it went away. I am a beginner. One of the crew (much more experienced) thought it might be normal or the forestay may need to be tensioned. I've sailed boats with roller furling before but, I don't remember having been in 20 knot winds so don't know if this is normal?

Your friend/crew may be correct. I would have the tension in the rigging checked out before starting to worry about more expensive repairs. If the vibration went away as soon as you bore off, that may be it. Cheers.

Are you sure it was the headstay? It is pretty common for the leech of a headsail to vibrate or flutter, especially if the sheeting angle is too far aft or the sail's leechline is too loose. The vibration can be quite strong.

Headstay

Aloha Paul,
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.
Peter
