Love the site/app I am constantly impressed with the information provided. In the way putting my vote in, I'd love to see a tide chart like the one user lumpet one and user wharfRat posted about. Also as others have mentioned the meter to foot conversion is not correct for tidal height, e.g. 0.23 meters is not 0 ft. Another thing that would be lovely is a graphical interface like this:
where tidal current stations have a graphical representation of direction of flow and water speed. Please and thank you! Keep up the good work!
