186 and rising...
My 320 has a current PHRF rating of 186. This is up from 180 last year. I am gathering data to make another appeal next year for more. The current is based upon 180 for shoal draft plus 6 seconds for roller furling. If you have a fixed prop, add 3 seconds per blade.I can look up the Beneteau 311 in the PHRF book tomorrow.Steve
