TZ Routing Module

TIMEZERO navigation software - Routing Module

Navigate safely and efficiently.

Like all sailors know, the most direct route isn’t always the best one. The new Routing Module now combines its revolutionary algorithm allowing you to calculate the optimal sailing route based on weather forecasts, currents, polars of your yacht and your own navigation style, with the powerful features of the former Advanced Routing Module to make one product.

More performance in routing calculation

The new Routing module offers accuracy and flexibility for the most demanding sailing conditions making the software routing calculation easier. It allows advanced sailors to manually control and adjust the weather file parameters in order to get more accurate results. It also introduces the variability notion, helping the skipper to identify the particular moments in the navigation where strategy choices are critical.

With our Routing Module, the safety of your crew is guaranteed. TIMEZERO routing algorithms based on the isochrones’ method is simple and automated for your maximum comfort. The Routing Module is the culmination of 25 years of software development in partnership with numerous sailing events around the world. It has been used and tested by the best sailors, but also by thousands of boaters.

Here’s the list of the new Routing Module features:

  • Waves are used for routing computation along with wind and currents
  • One click comparison between several routes and animations to evaluate multiple scenarios
  • Option to pass a waypoint, leaving it Port or Starboard during multi waypoint routing computation
  • Alternative Routing
  • Routing variability calculation and display
  • Weather File Adjustment

Its use is more intuitive and user-friendly for recreational boaters, while offering multiple setting options for experienced sailors.

Routing variability calculation and display
After having created a routing you can display on chart the variability.
Variability's value allows identifying quickly important variation of wind direction and strength which require from the skipper a supplementary expertise of his forecasts, routing and sourcing files.

  • The variability is equal to 100% if wind direction and strength are stable.
  • It will decrease to 80% if the routing shows important variations of the wind direction and strength. It indicates as well the weather transition for example a ridge with a gradient decreasing of pressure thus of wind.

Variability is symbolized in the Routing tree by a more or less strong display density (as it is shown in the picture above beside).

  • Areas colored in Black indicate weather transitions. A very dense black corresponds to a variability < 70 % and it is thus necessary to cross it in the shortest after an analysis more refined and recalculating a new routing before changing criteria as well as modifying parameters and files sources.
  • Light areas show the "Corridors" where weather conditions are more stable depending to forecasts.

The ability to overlay both together variability and Sailset allows you to clearly view each transition of different ways (as ridge) across the routing.
The Variability value is indicated in each line of the Routing center which corresponds to a time period of the weather routing.

Weather File Adjustment

It is possible to adjust the wind forecast data values, in order, for example, to take into account the hours or wind direction or wind speed, which has been prevailing in the zone for several days.


  • Increase or decrease the wind speed (%): move the cursor along the slide bar to modify to increase or decrease the percentage.
  • Increase or decrease the wind speed (value): enter directly a value.
  • Change Weather File Time: enter a specific time HH:MM.
  • Change Weather File in Latitude and Longitude.
  • Change Weather File Direction.
  • Increase or decrease in percentage Waves and/or Current values.
