[Rhodes22-list] too windy--Now Centeboard Effect

[cowie]

Lee:

I hope to get out sailing this Friday and Saturday.  I found a number of
discusions from the group on close haul sailing and what angle is reasonable
to be able to point in to the wind.  lots of variables, wind speed, chop,
genoa sheet location, sail size, centerboard position etc....  I
experimented a bit tacking back and forth in about 8kts of wind with all
sail up and sheets outside the stays and I seemed to get about 100 degrees
tack to tack or 50 degrees off the wind.  Plan to test this some more
adjusting all the variables.
