Something else to try! A mashup of code copied from the main program which allows the user to search for tidal data on selected dates.
BEWARE: Time zone used is the one set on your computer, not the station timezone, so check with tides from the main program for the offset, if any.
The harmonic data is the data in the main OpenCPN
The plugin allows the user to select from one of four locations, displayed after selecting the 'Tide Finder Position' item from the right click menu. The locations are based on the position of the cursor on the chart when doing your right-click. You may need to make the text for the locations larger by using the Tools options.
Runs with later 3.3 betas and O4. NOT 3.2.2.
The compiled plugin for Windows is attached.
Please let me know of any errors.
