Geoff's Navigation Site

The procedure for tidal data interpolation can become tiresome. Why not use a spreadsheet to solve problems like:

Getting tidal streams from tidal diamond information

Working out secondary port tides

Calculation of course to steer

I have written Excel spreadsheets which solve these problems without manual labour! Data is entered into cells which have a yellow background and answers appear in red type.

Tidal Streams

Secondary Ports

Course to Steer

The Compass

Leeway

Rule of Twelfths

Dilution of Precision

Collision Regulations
