Module 07 · Laying the route
Waypoints in clear water, each leg measured with the plotter and the dividers, the traffic scheme crossed at right angles, and the whole route from harbour to harbour in the plan sheet.
How the lesson starts
The straight line from Folkestone to Boulogne-sur-Mer, on the chart, is the shortest. It is not one you can sail: off Boulogne it passes 132 m from a charted hazard. On the way it meets the traffic separation scheme where it happens to: this time almost square, but a straight line crosses it square only by luck.
So a passage is laid as a string of legs, each one straight, from one waypoint to the next.
What a waypoint is
A waypoint is a point with a name and a position, in clear water, that you can recognise when you get there: a buoy, a point off a headland, a landfall buoy.

This is a preview. The lesson itself is interactive: you work through it step by step, and every answer is checked as you go.
