What do sailing yachts and canoes have in common? They can’t float without enough water!
This module looks at tides and the impact they have on boating. We explore how to find the depth of water at any time, anywhere. In tidal areas, the rise & fall of the water will likely have a significant influence on us and knowing how to calculate how deep the water is will open up a whole world of new places to explore.
Module Prerequisites
Before learning about tides and depths of water, you need to understand charts and positioning. Water depth is only relevant if you know where you are in relation to it! Don’t worry; we’ll walk you through each step step-by-step, making sure you are confident in the subject.
Learn tools and techniques to position yourself on a chart visually & electronically.
Skills Covered
This module discusses finding and interpreting tidal information, including sources from Nautical Almanacs to Mobile Apps. Once completed, you’ll be confident about how deep the water will be using traditional and electronic tools. Moreover, you’ll have the Tidal Heights Insignia to show for it!
Tidal Heights
- I know how to work out the depth, anywhere on a chart.
