Tides and tidal calculations

OOW-3000-M1 · Written: Navigation & Radar · OOW-3000-M1-A The IAMI Navigation & Radar written paper (2.5 hr) and its underpinning knowledge.

Tides decide whether there is water under the keel and how the stream will set the ship off track, so tidal calculation is a bread-and-butter skill for the OOW. This lesson covers what causes tides, how to work the height of tide at standard and secondary ports, and how to allow for the tidal stream.
