Sorry, this is the EUTidalCurrents plugin mentioned some time ago on this forum.
At that time it relied on users making up a folder of KMZ files to show tidal stream data. I made an example from public sources.

Working with 'Visit My Harbour' KMZ files have been produced from 20 UKHO Tidal Stream Atlases. Obviously these publications are copyright
. Users who purchase
or USB Stick of VMH UK/Ireland charts
and install OpenCPN (also on the media) have a protected folder called 'TIDAL STREAM ATLASES' on the media. For copyright
purposes the DVD/USB Stick can be moved to another machine but the data cannot be copied. The media needs to be attached to the computer running OpenCPN.

More information, including coverage, is shown at the bottom of the page.
The EUTidalCurrents plugin on the media and this updated version allows the user to select a folder corresponding to a UKHO Tidal Stream Atlas and view the tidal currents for each hour before/after HW at the base port. The tidal current information is raster as are the VMH charts.
The plugin needs OpenCPN V3.0.0 or better to run and 'libexpat.dll' in the main OpenCPN folder.
The updated plugin now uses tidal calculations based on Dave's code. This allows the user to select a date and the HW times are calculated for the base port for the Tidal Stream Atlas in use (not always Dover!).
The plugin coding relies heavily on SethDarts 'KMLOverlay' plugin.
My code needs a lot of cleaning
but could be put on github later if there is enough interest.
