Firstly - I'm in Oklahoma and there are no riggers near me.
I have a 1984 Hunter 34 with a B&R rig, with split backstay. We were sailing in 15 - 20 kts with gusts up to around 25. We would get this shimmy the whole time that I have never seen or experienced on the boat before. The spreaders would shift fore and aft in a twisting motion around the central part of the spar, that was honestly down right scary. I have a Loos gauge for the rigging and have put it on the rigging and while it is not perfectly aligned and I need to spend more time evening up port/starboard as well as do the halyard measurement it was not that far out. The D1s and D2s where right around 8 - 10% breaking strength.
We were flying full sail, traveled down and twisted off, and flying our 110 jib. We normally fly a 135 jib and had changed to the smaller headsail for the first time since owning the boat before our race due to the forecasted higher winds/gusts that day. We ended up finishing our race, but I want to figure out the cause of this before going out again.
Boat was last hauled a year ago and stepped and tuned with the loos gauge except for the forestay which can't be gauged because of the furling extrusion over it.
Any thoughts? My first thought was I may have developed some stretch on the forestay or diamond stays causing the shimmy?
