Sea Life is a lucky yacht, isn't she ?
This leads to the question when and how you use pilot charts.
If you are looking for reliable statistics when it comes to winds there is no better source than COGOW Climatology of Global Ocean Winds - COGOW
. This is based on data collected by Quick Scat, during it's total operational time. This is the best up to-date information, including the weather
patterns during the last ~10 years, and observations covers all
areas, not just ship reports. Maybe some day COGOW will be available as a KML overlay of OpenCPN or as vector chart.
The pilot charts, of course contains much more than wind
data, and ... are now available directly in your normal chart plotter, but the data is slightly dated.
Neither COGOW nor Pilot Charts says anything about the wind you actually will experience on a given crossing, but if you ever do a specific crossing multiple times, your average will be close to what is stated in the pilot chart.
Pilot charts are for planning long term, think seasons. Weather
forecasts are for the short term decisions. </rambling>
