How much water?

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.

This module is part of the Day Skipper theory course.
