I recently was lucky to come into possession of a 1930 Herreshoff 12 1/2. She is gaff rigged with club footed jib and I am excited to have her. Among the spars and accessory pieces was this curved piece that I can't figure out. It is asymmetrical in its curvature and somewhat tapered at one end. There is a hook type fitting at one end and an adjustable, pinned, slot fitting at the other. Has anyone seen anything like this before?
Completely befuddled,
David
