Displaying Weather Forecast on the chart

Display Mode

TZ iBoat lets you display the weather forecast in two different ways: either in "Online" mode, the weather will be streamed directly to your device or in "Offline" mode, the weather forecast will have to be downloaded to your device. The "Online" mode is very convenient (you can look at any area and see the weather immediately), but it requires an Internet connection. If you plan to be in an area without Internet connection, you should switch the mode to “Offline” and then download a specific an area (please refer to Downloading Weather Forecast for more information). You can change the mode at any time by selecting "Offline Chart & Weather" under the TZ button, then selecting "Download Weather" and switching from Online to Offline in the bottom left corner of the screen. Another way is to change the mode connection in the  Weather Settings.

Display on chart

TZ iBoat can overlay weather forecasts directly on your chart using particles (animation), colors, labels, or traditional arrows. To display weather, simply tap on the “Layers” button located on the bottom right of your screen and select the type of weather data you would like to see among Wind, Waves, Air Temperature, Clouds & Rain, Current, and Pressure:

Just below the type of weather data to display, you can select the type of presentation. Note that you can combine multiple display types if you wish. For example, you can choose to display wind in color + arrows + label.

Note that if the "Online" mode is selected and you have subscribed to the Premium Weather service, you can switch from one weather model to another, as shown in screenshot (1). If you have not subscribed to the Premium Weather service, the model section will not be displayed in the layers, because only one model is available: the GFS model. The same applies if the "Offline" mode is selected, because you can only download and view one model at a time.

Once a weather parameter has been selected, a time bar is displayed at the bottom of the screen:

The time bar allows you to play an animation (tap on the time bar anywhere) or you can manually drag it to a specific date & time.

Note that when you display the wind in color, you can switch the color range in between “standard” mode (0kn to 40Kn) and "light" mode (0kn to 20Kn) by clicking on the arrow located at the right side of the color palette:

In the screenshots below, you can see that the "light" color palette shows better wind variation in regular environment: 

The "standard" color palette may be more suited when you want to track storms or in high wind conditions.
