bad vibes

[gstej]

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!
