The table gives you a reference code for each day of the year (2003 and 2004).

The coastal outline offers varying colours, while the dial requires that you match the day code with the colour for the section of coast for which you want the tide time.

You then read off another section of the dial that references tidal slope indicated against clock time.

QuickTide cards are colourful, cover a wide area, predict two years, and cover thousands of miles of coast, including estuaries and the east coast of Ireland, plus the north west coast of France, up past Ostend to Vlissingen.
