    Harmonics tide file

    Hi,
    I have used the Harmonics tide file that comes bundled with OpenCPN in Expedition and notice a variation in reported data between the 2 platforms - Expedition seems to display different to OpenCPN and expected data for a given date.

    Any ideas?

    That appears to be a bug in Exp supporting the old xtide format.

    Have fixed & will post an update today. The values will have minor differences to Opencpn as the tide calculations are different.
