Larry Robinson tested the teardrop shape versus round shape for drag back in the early 90's. He found that the teardrop had less drag than the round section when the apparent wind was 31 degrees or lower. The round section had less drag when the apparent wind was over 31 degrees. More information, including stiffness comparisons, is included in The Manual for the East Coast 12-Meter by Robinson and Wells.

Help me with another memory problem
Somewhere, I recall seeing a comparison of the teardrop shaped mast with a round mast. The round mast proved less drag under certain conditions, the teardrop on others. As I recall, there were some illustrations with the discussion.
I've looked thru the manuals (both of them) and thru Tom Widdens book but can't find the info.
Does anyone else recall the location of this info?
