PredictWind DataHub and DataHub Pro both connect your boat's instrument data with the PredictWind ecosystem. The standard DataHub gives you the essential tools most sailors need. DataHub Pro takes everything further, with faster performance, Wi-Fi 6, LTE connectivity, remote boat access and additional monitoring and safety features.
If you are buying a DataHub today, particularly for a modern boat using Starlink and multiple connected devices, DataHub Pro is the model we recommend.

The core DataHub features
Both DataHub models give you access to the key PredictWind DataHub features.
GPS Tracking: Automatically share your boat's position and journey with friends, family or followers. Your tracking page can include GPS position, weather information, NMEA 2000 boat data, posts and videos.
AI Polars: Connect your boat instruments and let PredictWind learn how your boat actually performs, using your real sailing data to create polars tailored to your boat and sailing style, helping improve Weather Routing accuracy.
Data Streaming: Turn your DataHub into a gateway for your onboard instruments — GPS, AIS and NMEA data can be streamed over Wi-Fi so compatible apps and devices around the boat can use the same instrument data.
Over the Horizon AIS: Extends AIS visibility well beyond normal VHF range. With an internet connection, it can display vessels up to 300 nautical miles away on compatible chartplotters and navigation apps.
Anchor Alert: Monitor your boat while at anchor and receive alerts for conditions such as anchor drag, swing, rode and compatible NMEA 2000 data — particularly useful when you are ashore and want to keep an eye on the boat remotely.
Orca & Whale Watch: Display reported orca and whale sightings directly alongside your navigation data, giving greater awareness of recent activity in the areas you are sailing through.
Where DataHub Pro really stands out
This is where the difference between the two models becomes much more noticeable.
3x faster performance: DataHub Pro is significantly more powerful than the original DataHub — particularly useful on boats running Starlink, multiple phones and tablets, chartplotters and other networked marine equipment at the same time.
Wi-Fi 6 and faster networking: The original DataHub provides Wi-Fi speeds up to approximately 70 Mbps. DataHub Pro increases this to up to 1 Gb/s with Wi-Fi 6, giving significantly more bandwidth and improved connection performance around the boat. For boats using Starlink, this is one of the biggest reasons to choose Pro.
Built-in LTE / 4G: DataHub Pro has a built-in 4G LTE modem, powered by T-Mobile, keeping you connected for services such as GPS Tracking, Anchor Alerts and AI Polars when cellular coverage is available — so you don't necessarily need to leave Starlink running continuously just to stay connected.
Starlink Direct-to-Cell ready: DataHub Pro hardware is designed to support future Starlink LTE (Direct to Cell) connectivity. Availability, coverage, performance and supported use cases depend on Starlink and its cellular partners, including T-Mobile, and are not guaranteed by PredictWind; an external antenna is required.
Man Overboard App: If a Man Overboard event is triggered, the MOB position is marked on your connected chartplotter and alerts are sent to connected watches and smart devices, helping crew respond quickly. Email and SMS notifications can also be sent to selected contacts ashore. This works alongside, not instead of, existing onboard safety equipment and procedures.
Boat Battery Status: DataHub Pro can display compatible battery information available from your boat's NMEA 2000 network.
DataHub Connect: Allows you to securely access your boat's network remotely — instead of needing to be physically onboard and connected to the boat Wi-Fi, you can log in remotely and run your onboard apps from home, the office, or elsewhere.
So which DataHub should I choose?
Choose DataHub if: you want the essential PredictWind DataHub features — GPS Tracking, AI Polars, NMEA data streaming and PredictWind integrations — and don't need the additional networking, LTE or remote-access functionality.
Choose DataHub Pro if: you are installing a new DataHub or want the best performance and connectivity available, particularly if you use Starlink, have multiple devices connected onboard, or want faster Wi-Fi, LTE connectivity, remote access to your boat network, MOB monitoring, or battery monitoring.
DataHub is the essential marine data platform. DataHub Pro is the faster, more connected version, designed for modern onboard networks.
