Hi Al,
Hoist a fender up a halyard so it hangs somewhere between the upper &
lower spreaders and is near or alongside the mast.
Or, goggle vortex shedding and then after an hour or so of reading, see above.
It's nothing to worry about. Sweet does this occasionally.
Cheers, Russ

So I'm sitting at the dock with a 10 knot breeze on the beam and a
strange pulsating noise begins. You can feel it through the boat. I
go on deck and find it's the mast moving fore and aft at the middle.
Thinking it strange I tighten the baby stay and it slows but doesn't
stop. Anyone else have this happen? What to do?
Cheers, Al
