ADMIRALTY TotalTide (ATT) is the world’s most comprehensive tidal prediction program, providing bridge crews and voyage planners ashore with fast, accurate tidal height and tidal stream predictions for more than 7,000 ports and 3,000 tidal streams worldwide.
Instant tidal predictions and clearance calculations: enabling quicker and more informed decisions, ATT allows users to instantly calculate tidal heights for multiple ports during a period of seven consecutive days. Crews can also use the software to calculate and view safe clearances based on a ship’s draft, masthead and under-keel clearance allowance.
This information, which is quality assured by maritime experts at the UKHO, is presented in user-friendly graphical forms to help bridge crews understand predictions at times of peak-workload and pressure.
