Tidal Stream Calculation Form


The objective of this form is to calculate the tidal stream start and end times for particular parts of the coast along the Passage Plan Route, such as headlands and other areas along the route where we wish to take advantage of favourable streams, or indeed avoid headlands with unfavourable streams. This is of particular interest to sailing yacht skippers whose knowledge of streams throughout the passage can make the difference between a pleasant voyage or an uncomfortable one, particularly when the passage time exceeds more than one tidal period.


One side of the sheet allows you to enter data for your chosen area from a tidal stream atlas and tide tables for the high water reference port.

NOTE: An Excel program can be downloaded for free which will do the same job for you. Click here for more details. (Opens in new tab)


The reverse side gives full details of how to use the form, by going through a detailed calculation for a particular area.


The form is heat encapsulated within a premium matt plastic A4 size pouch which allows for  data to be written using a B grade black pencil. Details may be altered as required by erasing and re-entering. There is plenty of space on each line to allow easy entering of detail. Use several times.
