Anyone suggest a solution for this:

On my swing keel westerly nimrod I get an medim frequency vibration from the wire that lifts the keel. The wire is attached to the trailing edge of the keel, up through a hole in the bridge deck and onto a winch. If I completely lower the keel and take the tenion off the wire then the vibration stops, but the keel then bangs about as there is no way of securing it. So the question is how to secure the keel in the down position?
I should say that this is not the original arrangement, it looks like the winch was designed to be in the cabin with the wire taking a shorter route up through the top of the keel box. Finally the keel is about 200kg of cast iron with a bulb on the bottom.

ever thought of one of these high tech kevlar type ropes? could be every bit as strong, not prone to rust and should not vibrate in the same way.
