Secondary ports and complex tidal problems

RYA-THEORY-M2 · Coastal / Yachtmaster Offshore Theory · RYA-THEORY-M2-A Secondary ports, offshore passage planning, electronic navigation, meteorology and night collision avoidance.

Most harbours are not standard ports with their own tide tables but secondary ports predicted from a nearby standard port, so the coastal navigator must be able to work them. This lesson covers secondary-port calculations and the practical tidal problems they solve.
