Should I download ?
Yes if you have version 5.1 or above installed
If you have an older version, the data is believed to work, however it has not been validated with earlier versions and you are advised to update to the latest version..
Important
This updates only the yearly almanac data and not your harmonic constants (data for each port).
If you purchased the Worldwide Tidal Curve database, you are advised to check that you have the latest version installed, as the data may change (and sometimes significantly) as new measurements are taken. Please see price list.
If you have entered the port data(Harmonic constants) manually.
Please make sure you have updated the data as given in the latest edition of the Admiralty Tide Tables Volumes 1-4 , published yearly or in their abridged version. |
