You work hard and play hard, so when you’re by the sea you want to be sure of the tide – QuickTide tells you the tide times fast. On the card’s disk, you just align a colour and a code to display the approximate high- and low-tide times for a particular day for two years – the colour matches the coast colour on the QuickTide map. QuickTide cards are colourful, cover a wide area, predict two years, and need no calculations – with traditional tide tables you add an hour for BST, subtract say 2 hours 47 minutes for the coatal displacement, and convert from the 24-hour clock.
