I'm in the middle of buying I have bought a 1980 Freedom 30 CK (centreboard version). The first owner (who sailed long distances) replaced the aluminium wishbones with ones made from what appears to be steel, and although the boat sailed well when I went out for a trial sail, I don't much fancy heaving the booms up in the absence of a foredeck gorilla. I think I'll get new booms made. Could anybody tell me the specification of the tubing used to make the wishbones? Outside diameter and wall thickness?

Thanks for your help
