Next message: Brian and Elaine Timmins: "Re: [world-cruising] Chart Symbol Interpretation"
The chart in question is not a Pilot Chart. It's a regular "Georges Bank
chart, #13009. The symbol is as shown on Chart 1 as a Current Diagram. It
is very similar to the pilot chart wind rose, but different is not the same.
Thanks,
Brian
