In some cases it seems C&C did both hollow tube and solid bar, at the same time. On a construction drawing for the C&C 37 R and 37+, dated 1990, it shows the rudder post to be:
"3.15" O.D x 1.97" I.D. Hollow S.S. Bar w.2" dia. S.S. Round Bar pressed and welded" with the 2" round bar extending out the bottom of the 3.15" dia. tube, down further down into the rudder where the rudder was too thin for the full 3.15" stock. https://drive.google.com/file/d/0B7X4Y5iVFYAKVkdfbS1Qd19xa2M/view Ken H.
