Standard Port Tidal Curves Pdf How to do tidal calculations for european standard ports using the nautical admiralty tide tables.ask any questions in the comments i'll do my best to an. Tidal current diamonds there are tidal current diamonds in the chart with a letter in them corresponding to the letters in the current table. to determine the current direction and current rate, we need a tide table to determine the time of hw on the day in question for the port used as a standard for the current table (hoek van holland below).
Navigating Tidal Streams A Comprehensive Guide To Calculating Tidal Navigation and chart work secondary port calculations secondary ports all the ports that we have dealt with up to now have been standard ports that is ones for which tidal data is tabulated. however, most of the ports you visit will be secondary ports, at these ports you must calculate your own times and heights of high and low tide. most standard ports will have a collection of secondary. Watch on how to do tidal calculations for european standard ports using the nautical admiralty tide tables. ask any questions in the comments – i’ll do my best to answer them. this video uses an example of greenock, scotland to demonstrate the method and calculations involved to work out the height of tide on a given day and time. In order to provide tidal information for the hundreds of ports the antt provide detailed daily predictions for standard (large) ports and tables to calculate the difference at a secondary (smaller) port. Tidal calculations (standard ports) the wizard yacht masters amongst you will already be aces at this stuff but for other mortals and maybe a refresher, this top tip looks at using the tidal information from, in this case, the reeds almanac to perform some useful practical calculations.

Tidal curves for standard ports are found in admiralty tide tables and also in nautical almanacs such as reeds. for secondary ports use the curve for the relevant standard port. the almanac will make it clear which standard port you need to refer to. for example, the standard port for looe in cornwall is devonport (plymouth). Predictions for secondary ports are made by applying time and height differences to predictions at a selected standard port or by using the harmonic constants and the simplified harmonic method of tidal prediction.
