Tide Calculator helps you predict the times of Slack Water and shows when streams are fastest in either direction.


When you order a  'First Edition' we will research the tide times for your chosen location (anywhere in the world) and design your bespoke Tide Calculator.


You will be sent the files to download, print off on A4, cut out the templates and assemble the parts together. Once assembled, simply turn the wheel so the time of High Tide lines up with the black arrow and read off the times of Slack Water and maximum flow in either direction.


Please note: this option is for the First Edition so we need time to research the tides for your chosen location. This usually takes around 15 working days.
