There are times when I am sailing my Venture 222 that the iron keel will bang around inside the trunk a little bit. When I am on a reach it does not seem to happen but when I am running or sitting on the mooring it does it. Not a lot but I can hear it rattling around some inside the trunk.Is this something to be concerned with and if so how do I fix it. It is not a problem, I am just worried that with all of that weight flexing around down there it could damage the fiberglass of the trunk.Anyone deal with this? I did a search and could not find anything.
