Re: Tidal streams - Computation of rates.....

I don't think I have ever used that diagram.

It is only a method of interpolating between, or extrapolating from, the spring and neap rates that correspond to ranges at Dover of 5.9m and 3.3 m.

In the real world most of us would guesstimate but if you really want precise figures (note I said precise not accurate) I would suggest you use the Tidal Atlases by Michael Reeve-Fowkes for both rates and heights and relegate the classroom methods to the mental archives.

Danny is correct in saying that the diagram you are after is in the Admiralty Tidal atlases.
