Safe Port Entry Calculations
Predictions are enhanced by the calculation of periods for safe port entry based on vessel draft and masthead height. Results are presented clearly in a simple diagram and summarised on a tidal graph.
 

Global Tidal Stream Information
TotalTide calculates tidal stream predictions for over 3,000 tidal stream stations worldwide. Real-time tidal stream rates and direction predictions are overlaid on a detailed chart display and updated every 60 seconds to maximise situational awareness.
 

Comprehensive Search Facilities
TotalTide's sophisticated chart interface provides the mariner with a full geographical search facility. Fast text and coordinate-based searches are also available to take users directly to specific tidal information.
 

Option to Customise Data to Trading Patterns
Standard and secondary ports can be grouped and saved in special user-defined files based on specific routes or trading areas, meaning that information retrieval is quick and easy. Toolbars, screen layouts and views can be customised to suit individual fleet or vessel requirements.

Optimum Safety and Functionality
TotalTide contains all standard and additional information included in Admiralty Tide Tables, including Chart Datum Connections and tidal levels for standard ports, plus periods of daylight and nautical twilight, moon phases and a springs and neaps indicator. Special night and twilight display options ensure optimum visibility at all times.

Full Print and Export Facilities
Tide prediction results for periods of up to seven days can be printed or exported in a range of formats including MS Excel and ASCII for use in other navigational and operational activities such as passage planning. TotalTide's prediction algorithm can also be used to calculate tides from privately held harmonic constants.
 

Maximum Flexibility
TotalTide offers complete global coverage on a single CD. Split into seven area sets, users can simply select the areas required, and add to coverage at any time. Instant access to additional areas can be quickly and easily obtained in an emergency situation by telephone, fax or email.


TotalTide includes a FREE second user licence for back up purposes, meaning that safety critical information is available at all times in the event of a system failure.

Annual Update Service
The harmonic data used in TotalTide is updated annually to ensure accuracy of predictions. Whilst TotalTide will continue to predict tidal height and tidal streams indefinitely, the UKHO recommends that users update area data sets every twelve months in order to maintain accuracy. Annual Updates can be purchased each January from appointed Admiralty Distributors.

Carriage of Nautical Publications – Equivalent Status
"The UK Maritime & Coastguard Agency (MCA) accept TotalTide as meeting the requirement to carry the tide tables under the Merchant Shipping (Safety of Navigation Regulations) 2002, which came in to force on 1^st July 2002, on the understanding that TotalTide is operated on a conforming computer system, a permanent security key has been installed and the most recent update has been applied" – MCA

This means UK flagged vessels and other vessels navigating in UK waters can use TotalTide instead of carrying paper tide tables onboard.

Please note, other non-UK regulatory authorities may regard TotalTide as purely an aid to navigation and not as an equivalent to the paper product. Further approvals are pending.
