I was under the impression that all the Prindle 16-19 rudder systems were all the same, it appears there is a difference in the blades. The early 19 blade is a bit shorter, the bottom is 90 degree to the trailing edge. Anyone ever run across this.

Might it be because the 16 and 18 have assymetrical hulls while the 18-2 and 19 have centerboards (so the rudder does less work)?

LOnger boat, taller mast. Stands to reason rudders are more out of water going downwind. Do not buy rudders listed in San Diego by Scott. He took a wire transfer from Dave in Tulsa for boat, then skipped--is now parting out boat--beware. Pete
