Tidal Definitions video animation

//
Comments1

This Tidal Definitions video forms part of our Tides Masterclass which is coming soon.

It’s important when we are learning to navigate that we understand what the different tidal definitions refer to. If we don’t then we run the risk of calamity by using incorrect reference points.

This could mean running aground, hitting a rocky reef or even colliding with a bridge.

Spring and Neap tides can mean the difference between access to a harbour being possible or not.

The different ranges during spring and neap tides are also relevant when you learn to calculate tidal streams and when using tidal curves for standard and secondary ports.

Everything you need to know is in the Tides Masterclass.

You can get another free taster of the Tides Masterclass by taking a look at our secondary ports post here:

    Hi,
    thanks for this simple visualisation. And that the ‘secondary ports’ chart below already points out that some places have (spring) tides that go below chart datum. And of course, LAT/HAT are ‘astronomical tides’ – the weather can push tides beyond either, in ways that are not entirely predictable (at least, so far as I can see!)
