Vessel operators in coastal waters need to be very mindful of the effect of tides and tidal currents caused by the gravitational pull of the sun and moon.

Water levels can fluctuate by several meters and some tidal currents are strong enough that pleasure craft may not be able to make headway against the current.

This course will guide you to develop a complete understanding of Tides and Currents, enabling you to make navigational decisions that will enhance safety on your vessel.

Digital version of notes will be emailed to participants prior to seminar day
