This device is ideally suited for GPS tracking and comes with an internal GPS. To transmit the data back to PredictWind simply connect to any mobile data or satellite service, i.e. a mobile hotspot on your phone or a Starlink connection.
GPS tracking is a key safety feature, where friends and family can see your boat’s position, and the speed along your route. For it to be safe, it is paramount the solution is reliable, and so a dedicated GPS tracking device is essential.
Tell your Story
In addition to showing your position to friends and family, you can also post blog posts that correlate with your GPS position. Share the adventure as it happens!
No Communication Costs*
The DataHub connects to your existing mobile or satellite communication device, so no additional monthly subscriptions are required. *Additional charges may apply due to increased data usage.
With the DataHub you can use the high quality built in GPS with stub antenna, or alternatively connect to the boat NMEA 2000 (N2K) GPS. With your boat’s external GPS antenna above deck you can be guaranteed of accurate GPS position data.
Store & Forward GPS data
If no Internet connection is available the Datahub will simply store the GPS data on the device, and then automatically send the data to the PredictWind servers when the unit gets a mobile Internet connection.
Connect with other boats
Using the PredictWind Local Knowledge feature you can find and connect with any boat that uses the PredictWind GPS Tracking service or a vessel transmitting AIS data. PredictWind has the largest network of boats using GPS Tracking/AIS in the world.
Showing friends and family your position on the chart with PredictWind GPS Tracking is a great safety feature, but imagine if they could also see your actual wind conditions from your boat's instrumentation. The DataHub makes this possible with a built-in N2K interface to your instruments, that enables Wind Speed and Direction data to be viewed on the PredictWind GPS Tracking page.
Broadcast GPS data via WiFi to all your tablets/laptops, so other navigational apps can benefit from this highly accurate GPS position data. Do not be caught out when navigating narrow passages, as the GPS in your tablet will never be as accurate as the Datahub GPS, or alternatively the DataHub interface to the Boat’s external GPS antenna. This eliminates the need for products like the Garmin GLO that require charging, and are not designed to be mounted externally.
Broadcast your Internet connection to all of the devices onboard. This can be useful in the case where a mobile provider only allows for one hotspot connection. The DataHub can circumvent this limitation. The Datahub can get an Internet connection via an ethernet cable, WiFi hotspot, or simply use a USB cable to connect to an iOS or Android device.
The DataHub samples your boats NMEA 2000 instrumentation data in real time while the boat is sailing. Then the data is transferred to PredictWind servers for automated analysis to create your own custom boat polar. Getting an accurate polar (performance of the boat) is critical for meaningful results in the PredictWind advanced Weather Routing and Departure Planning features.
*Feature available in Q1 2023
The DataHub can store GPS tracks and instrumentation data for downloading, viewing, and analysis. This data can also help with insurance claims in the unfortunate case that your boat is lost or damaged in rough seas/weather.
The PredictWind DataHub’s remote access feature allows support personnel to log in remotely to the unit to diagnose and solve issues on the vessel. This can save valuable time since vessel technicians can access both the vessel's NMEA 2000 and TCP/IP networks.
The DataHub collects AIS data from all surrounding vessels and transmits this back to the PredictWind servers to improve the quality and safety of AIS data worldwide. The DataHub also transmits your AIS data feed to any compatible devices on board.
Start transmitting AIS data from your vessel with the PredictWind Datahub now to get 10% off your next PredictWind subscription.
Historical AIS and GPS data can be useful in the event of collisions, to determine who is at fault, for insurance claims. If your boat does not have an internet connection whilst at sea, AIS and GPS data will be stored on your Datahub and transmitted once you have an internet connection again.
“The DataHub was able to broadcast our highly accurate Raymarine GPS over WiFi to all our devices on the boat.”
“WiFi calling, Zoom, Skype, Netflix, Amazon Prime video, Amazon Streaming Music... it's all available easily now on Bliss thanks to DataHub.”
“It has been really advantageous to have the PredictWind DataHub onboard.”
Why do I need the DataHub?
When you travel offshore, you need a satellite device like the Iridium GO! to download weather routing and GRIB files, and have GPS tracking, but once you are inshore, you can cancel your airtime plan to save money. Then, the DataHub can seamlessly take over and continue updating your GPS tracking page using cellular data around the coast as it connects to your cellphone hotspot, USB tether, or local Wi-Fi. Even if you drop in and out of cellular coverage, the DataHub will collect position reports every hour and then send that spool of data to PredictWind to update your tracking page as soon as you regain cell coverage again.
Another great thing about the DataHub is that it can create a Wi-Fi hotspot for multiple devices to connect to. Many cellular data plans only allow one device to hotspot unlimited data (you may need to check if hotspot data is limited on your data plan). If you connect your mobile phone to the DataHub, this becomes a Wi-Fi repeater, and multiple devices can connect to the DataHub and use that cellular data. Then, you are not restricted to just one hotspot, and the whole family can use data from one phone plan. The DataHub can get cellular data by hotspot, Wi-Fi, USB tethering, or Ethernet.
Do you need an Iridium GO! or other satellite device if you have the DataHub?
The DataHub is not a Satellite Communication device. You will still need the Iridium GO! or some other satellite communication device when you are offshore, so you can download weather data and send/receive SMS and emails.
How do I use the DataHub for GPS tracking?
The DataHub has a built-in GPS antenna which enables you to have GPS tracking when sailing coastal. It uses your cellular data to send the position reports as it collects them. When you are out of cellular coverage, it can save your GPS position reports and upload them to your PredictWind tracking page when you are back in range.
Does the DataHub require an ongoing subscription fee for any aspect of its functionality?
There is a one-off cost to buying the DataHub hardware. You also require the standard or professional level of PredictWind forecasting subscription to utilise the tracking and polar generation (coming soon) features. Click here to see PredictWind forecasting subscription prices.
Where can I find the DataHub manual?
You can download the DataHub manual here.
Do I need the NMEA 2000 M12 Cable Pack?
If you have a network on your boat, the cable pack allows the DataHub to connect to your boat's existing NMEA 2000 (N2K) network. Then the DataHub can utilise the external GPS and other devices on the N2K network. Insert the T-Connector into your N2K network, then connect the 2m cable to the DataHub, and you're away!
Should I use the DataHub with Starlink?
The DataHub works seamlessly with your Starlink device. PredictWind GPS tracking is automatically updated by the DataHub using your Starlink connection. AIS targets can be collected and distributed adding to the AIS network. The DataHub will prioritise your internet connection if one drops out, automatically swapping between LTE/mobile, Starlink, Certus or other connections you have on board.
