[Rhodes22-list] Close Haul Question

[Peter Thorn]

Lee,

You are talking about a polar diagram for R22 to reveal VMG at different
angles to the wind.  Not sure if I've ever seen one, but someone out there
might have this data.  Lots of other conditions factors effect VMG too: wind
intensity and waves.
