Theory course

Day Skipper Theory

The navigation and seamanship knowledge you need before you are allowed to skipper. Chartwork, tides, buoyage, collision regulations and weather.

This is the first serious theory block and it underpins everything that follows. You learn to work a paper chart with plotter and dividers, fix your position, apply tidal heights and streams, plan a short passage, read a synoptic chart and understand the collision regulations well enough to act correctly at sea. Australians often do this online over several weeks or as an intensive classroom week. The knowledge is assessed by two written papers (a navigation paper and a general paper) at the end of the course.
