The Weather Routing module combines with both TZ Navigator and TZ Professional to provide a route that will optimize the time taken to travel on a sailboat using the weather forecast information and your boat’s polars.

Always take the best route!

TIMEZERO’s roots trace back to racing and pioneering the racing world by being the first to develop an algorithm to optimize the best route based on the forecasted wind, waves and currents as well as the polars of your boat. The weather routing module provides the fastest way to get across the finish line.

Sailing at sea with friends or family is an adventure of a lifetime. Having the best routing software at your side will help you become more prepared against the elements making the adventure more enjoyable.

Be prepared whatever the weather throws at you. The Weather Routing module is a simple yet powerful tool which calculates the fastest route for a sailboat. Weather forecasts and polars allow the TIMEZERO software to provide an extremely accurate calculation on the fastest route from point A to point B.

Your coastal navigation has never been this easy, safe and optimized. Our Routing calculation automatically avoids the coastline for the best route and can be done in only two clicks: one on your departure point and the other one on your arrival point!

Anticipate easily the parts of the route where you should be motoring thanks to the colored legs and maintain the best conditions along your route.

Display the expected wind conditions along the track to know exactly what the wind conditions should be at every leg along the track.

This takes the leg work out of deciding your route and lets you relax in the knowledge that you will get to your destination in the quickest time possible. Whether you are sailing to win that race or simply setting sail for new destinations, take the Weather Routing module with you.

Wind speed cap and wave height cap are new features that now allow sailors to sail in security by limiting these two variables.

This is convenient for those times when you’re not always trying to beat the clock. So you can optimize your travel time while ensuring your safety from adverse weather conditions at sea.

You now have the ability to check for an alternative route. A great addition if you want to avoid a certain zone such as when sailing near the coast line.

The new version of the Weather Routing module goes even further by allowing you to fine tune the calculations with even more precision. This module now includes a risk variable, a feature developed while working closely with Michel Desjoyeaux, two time Vendée Globe winner.

This feature displays zones with high risk, such as a dramatic change in wind speed and direction. It does this using an easy to identify shading spectrum, from which a decision can be made to launch an alternative route.

The professional version of TIMEZERO allows you to accede to advanced features, critical for sports competitions. Thanks to TZ Professional combined with the Weather Routing module, you will be able to follow targets to work on your competitors routing.

In addition, you can save your routing and those of your competitors using the layers, this way you can analyse strategies and optimize yours.

The algorithm used by the weather routing module is extremely reliable. For over 30 years, we have equipped the most demanding sailors. The module has also been integral in winning some of the legendary off-shore races, such as the Vendée Globe and the Transat Jacques Vabre!
