Swing keel houseing,and subkeel.
My plan is still quite fluid but the keel was removed by previous owner because of corosion issues at piviot pin. The piviot pin was embedded in f-glass at the bottom of sub keel. Poor planning for maintanence!
My thought with the tubeing bolted to base of keel was to provide an easier pin point,and only extend the subkeel about 4 inches. The tubeing could be used to suplament the loss of the iron keel wirh lead ingots in the tube. And replace the iron swing keel with plywood and F-glass encapsulation. Keeping the swingkeel.
Past owner passed away,dont know what happened to keel!
