More on the weather:

Local knowledge and the weather...

Local knowledge is also frequently craft-specific.  The locals
may
be accustomed to Sea of Cortez pangas or out-islands Bahamian
Carolina skiffs or the inflatable high speed craft used to
transport kayakers in the Queen Charlottes.  All will
understandably have quite different views of "good" and "bad"
conditions, what is a "significant" change in rate and intensity
of wind, waves etc.  Ask about the weather but make considered
judgments based upon you own experience.  

When "local knowledge" is insufficient...

We have just returned from kayaking in the Jumentos Cays, 65
miles north of Cuba at the eastern edge of the Bahamas Bank. 
Population of 30 within 600 square miles.  No VHF, NOAA, or other
ready made weather broadcasts.  In these circumstances we pieced
together a patchwork of AM, FM and SSB broadcasts from radio
stations in Florida, Cuba and the offshore SSB data provided by
the U.S. Coast Guard.  The trick was to identify all the relevant
frequencies and times in advance and have them handy
(pre-programmed into your radio if possible).  Most broadcasts
are not continuous but less frequent -- every 6 hours typically,
last only a half minute, and must be recognized by reference to 
latitude/longitude or general area.  SSB broadcasts used to be
the purview of big boat folk but now there is an alternative. 
The SONY World Band Receiver ICF-SW100 comes with its own tiny
active antenna and will receive all frequencies in the AM, FM and
SSB bands with excellent
quality.  It also weighs a whopping 7.8 ounces, is 4.25" x 2.25"
x 1" size, and runs on 2 AA batteries.  
	Christmas evening, after our afternoon snorkel, we shooed the
scorpions away settled on the sand and prepared a festive meal,
then propped this little beauty on a rock and listened to
Bahamian regee-Christmas broadcasts from Nassau, traditional
carols from BBC in London, the news from Radio Havana and danced
in our undershorts on the beach as the sun set.  Don't ask about
the price, but it is is an amazing, compact and high quality
radio that is fun as well as functional.

Happy paddling and happy New Year to all.

How did you determine, ahead of time, what freqs, modes, and times to use?

This was from a mixed bag of sailing guide info from Captains
Nautical in Seattle which provided numerous
station/frequency/time references and some web browsing.  Radio
Havana answered my e-inquiry directly with a listing of
frequencies/times/program content.  The "local knowledge" of
greatest use in weather prediction near northern Cuba was to ask
fisherfolk and others where/when broadcasts could be heard. 
Often broadcasts of the same information are carried on different
frequencies.  I found that the recommend frequencies were not
always the same nor were they those on which I found the best
reception.  Some experimentation and a bit of record keeping was
necessary.  The sailing community is better orgainzed to share
this material.
