PHRF is not perfect. I would put money on there being little difference if we sailed our boats side by side. 136 was based on the code 6 main that is no longer. My rating will be 139. OD base rating is 138. If I were to only carry my 3/4 oz spin I think I would be 141.

I would be racing in true OD config so it is fair to race heads up OD. Not my fault if you choose to slow down :P
