The Marine forecasts feature allows you to access some key information to better plan your next trip or to just know if going out to sea today is a good idea.

NOTE: It is necessary to have an active Master subscription to have access to the Marine forecasts.

Marine forecasts setting page

From the main Settings page you can open the Marine forecasts page; here you can customize and modify the way your forecast data is displayed on the map.

At the top of this page, you have the switch to enable the display of the Marine forecasts on the map.

Then you are presented with more option to define what you want overlaid on the map.

You can select one option at a time from the following:

Surface currents: Displays on the map the speed and direction of surface currents in all oceans and major seas (data sourced from the RTOPS and RIOPS models). Additionally, the app features highly detailed models for the primary US estuaries (data sourced from NOAA).
Wind (at 10m): Shows on the map the speed and direction of wind (at 10 meters above the surface) worldwide, the app utilizes the HRRR model for the US and the GFS model for the rest of the world.

Next, you can adjust the following settings:

You can make multiple selections:

Symbols: Choose to display forecasts as directional icons, with their color and size representing key information (e.g., wind speed or wave height).
Colors: Opt for a colored overlay that represents the main information (e.g., wind speed or wave height) of the selected forecast.
Labels: Display key information (e.g., wind speed or wave height) as text, overlaid on the symbols if enabled.

Then, you can adjust some parameters that affect how the data is displayed on the map.

Text & icons size: Select the size of the icons and text.
Icons density on map: select how many icons are displayed on the map.
NOTE: selecting both options at the max value will cause to have a very cluttered screen.

Finally you can select if the legenda has to be shown on the map or not.

Marine forecasts on the map

Here are some example of how different data is overlaid on the map (from left to right: Wind, Currents, Waves).

To enable the Marine forecast overlay you can open the "Marine forecast setting page" (described above) and switch ON the "Enable overlay".
But there is a quicker way to do the same directly from the map, tapping the "Marine forecasts" button (just above the Settings button on the bottom-right of the map screen).

After tapping on it, you will have the opportunity to select the data to be displayed.
NOTE: after you select an overlay, the Marine forecasts button will change to show the selected data.

To disable the overlay you can tap on the "Marine forecasts" button and select the currently active data (eg in the image above, tapping on the Currents icon will cause to disable the Marine forecasts overlay).

When you enable the Marine forecasts overlay, what you see is the nearest (to your current time) forecast but it is possible to explore the forecasts for the next 40 hours.
Tapping on the button (just above the Marine forecasts) you will start a forecasts simulation, allowing you to select and view any time (with a 1 hour step) in the following 40 hours.

When the simulation is active you can use the slider to select your desired time or using the or buttons you can move backward or forward.
NOTE: the data is downloaded from Internet when requested, so you need to wait some seconds for it to fully load.

Tapping on the button will close the forecasts simulation, and the data display will go back to the actual time.

Weather forecast for a point

In the Map Information page you have a dedicated row with a brief description of the current weather situation for the selected location. If you tap on this row you get a new page containing the detailed weather forecasts for the same position.
NOTE: This info is retrieved from the Internet, so you need to have a stable and strong Internet connection.

In this page you have three or four different sections:

NOAA Marine Text Forecasts: This service from NOAA provides weather information and navigation advice for specific areas in the US. Tap on the row to open the dedicated page (see below for an example).
Current weather: Shows the main weather information for the selected location at the current time. In the bottom section of the page, you can also find the sunrise and sunset (and moonrise and moonset) for the day. The background color of the view is light blue if it is currently "day" and dark blue if it is currently "night."
Hourly forecasts: Displays synthetic weather information for the next 48 hours with a 3-hour step in the US and a 1-hour step in the rest of the world. You can scroll horizontally to access the next hours.
Daily forecasts: Provides very concise information for the next 7 days.

Weather buoys

Using the dedicated switch in the Settings page, you can display on the map a special type of icons respresenting "Weather buoy". These buoys provide real-time weather conditions at their location.

So, when you tap on one of these icons, you get a popup like this one:

Then, tapping on the icon opens a dedicated page with the latest weather conditions at the buoy location.

NOTE: The page is retrieved from the Internet, so you need to have an stable Internet connection to access this information.

Depending on the buoy, you can receive various types of weather data, including wind speed and direction, wave speed, direction, and period, pressure, visibility, air and water temperature. Additionally, some buoys provide textual information for the surrounding area.

To easily locate the weather buoy you are interested in, you can search among all the currently active weather buoys on the Search page, where there is a dedicated switch in the "Places & POI" filters.
