The SFBA windtalker, a PRIVATE number for SFBA members only, send in your
$10 or don't call, is on the Berkeley Yacht club. It reports the wind
in knots (correctly!). It is reliable in winds from NW, W, SW and S.
Since these are the best sailing winds in that part of the bay, it seems to
be ok. I BELIEVE IT READS LOW. It reports the wind a little low but
very CONSISTENTLY low. The SFBA members who call it all the time have
calibrated their brains and tell me they find it very useful.
The call of the wind windtalker is on the restaurant (lordships). It
is good in W, SW, S, and SE winds. It is blocked by a tree in north winds,
this makes it slightly less useful for clearing winds, but it works fine for
the usual summer SW stuff. It reports the wind in mph (oops). It is
mounted higher than the SFBA windtalker.
You have seen them report different values, but I have seen them report
the same wind, after correcting for knots and mph. 1 knot = 1.15 mph.
The moral of this story - send in the money to the SFBA, call their
windtalker, go down there and rig any time it says SSW or SW at 14 or
15 or more.
Or get a pager and use that all the time. Whatever.
