Routing

The "Routing Module" needs to be unlocked to access this feature

The Routing options allow users to configure settings that will change the Routing computation:

• Only Keep The Last Routing: By default, TimeZero only keep the latest routing. This means that when creating a new Routing, the previous one is discarded. If you want TimeZero to keep all routings on the screen (to test multiple scenarios for example), uncheck this option.

• Routing Transparency: Adjust the isochrons and sailset transparency on the chart.

• Isochron Interval: Adjust the time interval in between two isochrons. By default, TimeZero adjust automatically the isochron interval according to the routing distance. You can manually select a smaller isochron interval (to increase accuracy), but keep in mind that this will increase the computation time.

• Use Motor Under Sailing Speed: Set the minimum speed that will be used underway. When predicted speed (from Wind Power) fall under this value, TimeZero will assume you will start your engine and use the speed below to predict the rest of the voyage (until the speed under wind power goes above this threshold again)

• Motor Sailing Speed: Set the speed under engine power.

• Polar Curve Percentages: Allow to adjust the overall polar speeds. This settings is especially useful to decrease the overall polar values when feeling that you cannot reach 100% efficiency.

• Avoid Land and Shallow Waters: When this option is enabled, TimeZero will try to avoid land and shallow water areas under whose depth fall under the setting below.

• Minimal Depth: Set the minimum depth.

• Waves: Check this option of you want the routing computation to take into account wave height and direction.

• High Resolution Tidal Currents: Check this option of you want the routing computation to take into account the high resolution tidal current (the routing will not use discrete tidal current stations).

• Oceanic Currents: Check this option of you want the routing computation to take into account the oceanic current (from weather file).

• Maximum Acceptable Wind Speed: Enter the maximum wind value acceptable along the optimized route. Use this field if you want to avoid area with strong wind. Leave the default value (125!) if you don't want to put any restriction on the routing computation.

• Minimum Acceptable Wind Speed: Enter the minimum wind value acceptable along the optimized route. Use 0 if you don't want to put any restriction on the routing computation.

• Maximum Acceptable Wave Height: Same as above, but for wave height.

• Routing Label Prefix: Prefix used for the default name of every routing. Since routing will also appear in the route list, it is common to give a specific prefix for optimized (routing) routes.

• Routing Auto Numbering: Used with the prefix to assign a default name.
