FIRST EDITION

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 (we recommend the thickest paper/card your printer can take), 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. Due to high demand and the fact that every design is custom-made, waiting times are up to 6 months for commissions. Please allow up to 15 working days.
