I keep my '97 Rhodes 22 on the Boca Ciega Bay of St. Petersburg, FL , docked
on a lift, with mast
up, at my back yard seawall, on the St. Pete Beach island side of the bay.
The dock is fairly well
sheltered around all points,except the North. The periodic winter cold
fronts blow in from the North
with 20+ knot gusty wind which produces a horrendous wailing howl in the
rigging/mast.
 
While docked, the boat's stern faces NE ; it seems to me the wailing noise
must be caused by the wind entering the IMF's hollow mast groove and then
exiting near the top producing the howl, like an organ pipe. I don't think
the noise is from the shrouds.
 
Please let me know if any of you have experienced or heard of someone else
running into something
similar, with any IMF system. If so, has anybody come up with a method to
mitigate this problem,
other than lowering the mast / derigging or docking the boat so that the
stern (and mast groove)
faces to leeward?
 
Your comments will be very appreciated, so I thank you in advance,
 
Al Keblinskas
