I meant jibstay. too long ago, Mathematics was my field, so I owe it to myself to work through the trig.

Thanks again!

Well, more that three times now I have felt the vibrations in dead calms.

I now think vortex shedding is unlikely. More than anything the vibrations do seem to coincide with unusually high tides, so I am convinced it is related to water flow and I am overly sensitive (or paranoid?)... unless there is a better theory to account for this.

What great forums, thanks all!

If you are feeling the vibrations in dead calms, could they have been generated by propellers? Maybe outboards on small boats that are not readily visible? Or could there be some other source not on your boat?
