The second generation DataHub 2.0 is a GPS tracking device packed full of new features to make your marine data and communications easier and safer than ever.

GPS tracking page for updates and safety


Share your GPS position, live weather, blog posts and photos, with friends and family. This alerts everyone watching if your boat stops or goes off course with a potential safety issue onboard.

No other device allows you to share your live wind speed, wind direction and boat speed to your GPS tracking page.

The DataHub uses the GPS data from your instrumentation system, for 100% accuracy and reliability.

GPS tracks are saved while you’re offline, then uploaded once your connection is restored.

Our new AI Polars reference real-time data to learn the way you sail your boat, to create hyper-accurate weather routing.

Simply plug in the DataHub to your boat's instruments and turn on the automatic AI Polars. PredictWind will then track your boat’s real-time data and automatically create an optimised boat polar for your unique vessel and sailing style.

View your boats position, live N2K data and weather forecasts, on or off the boat. Customise your alerts then relax knowing your boat is in good hands, with the Anchor Alert App.

Broadcast your internet connection to all of the devices onboard. This is useful when a mobile provider only allows for one hotspot connection.

Collect and upload AIS data from all surrounding vessels to the global AIS network. Also share AIS data with navigation apps such as Navionics.

Use AquaMap, OpenCPN, iNavx, MacENC or GPSNavX to control your autopilot with the DataHub N2K interface.

Record GPS tracks, and key instrument data for future reference or in the event of a collision or insurance claim.

Allow support personnel to log in remotely to the DataHub to diagnose and solve issues throughout the entire vessel.

Automatically switches to your 4G/5G backup connection if your primary internet goes down, so you’re always connected.

Introducing the DataHub 2.0 - New Features

Every boat sails differently, but equally, every sailor sails differently. Our new AI Polars will optimise your routes based on your boat’s real-time data and your unique sailing style.

Boat polars represent the performance of your boat in different wind conditions and are critical to creating accurate weather routing results.

Our new AI Polars reference real-time data to learn the way you sail your boat, to create hyper-accurate weather routing.

Up until now this was limited to the realms of professional navigators. PredictWind now makes it simple and easy to get accurate, personalised polars for your boat. This ensures your boat’s location matches the predicted weather route, resulting in a more accurate forecast.

Simply plug in the PredictWind DataHub to your boat's instruments and turn on the automatic AI Polars. PredictWind will then track your boat’s real-time data and automatically create an optimised boat polar for your unique vessel and sailing style.

AI Polars also factor in wave conditions and comfort preferences for realistic weather routing. Hydrodynamic modelling analyses your boat’s unique motion in all wave conditions to give you the most accurate routing on earth.

Weather Routing personalised to the way you sail

PredictWind, the world leader in marine forecasting, has unveiled a groundbreaking innovation that will redefine the future of weather routing with Automated AI Polars.

Sailors know that no two boats – or skippers – are alike. Recognising this, PredictWind's AI Polars are engineered to optimise routing based on your boat's real-time data combined with your distinctive sailing habits. By understanding your boat's behaviour in all wind and wave conditions, the AI Polar automatically adjusts to give you more accurate routes than ever.

Previously, personalised polars were the exclusive domain of elite navigators. PredictWind has now made it easy and intuitive for every sailor. "With our AI Polars, we are bridging the gap between professional navigators and recreational sailors. Now everyone can benefit from hyper-accurate, tailored weather routing," says Jon Bilger from PredictWind.

Using this feature is as easy as plugging in the PredictWind DataHub to your boat’s instruments and activating AI Polars. The technology springs into action, capturing and interpreting vital data points like boat speed, wave conditions, true wind speed, and true wind angle. In addition, hydrodynamic modelling intricately predicts your boat's movement. In addition, the weather routing predicts the performance effect of the waves on the routing, offering the most precise routing output available.

With the inclusion of wave conditions and individual comfort preferences, PredictWind ensures not just optimal but also comfortable routing. AI Polars also guarantees accurate data by smartly filtering out times when the boat is anchored, motoring, or motor sailing.

Once activated, AI Polars aren’t static. They evolve, consistently harnessing new data to refine and perfect your personal boat polar, enhancing precision with every nautical mile you cover.

PredictWind continues to lead the marine forecasting frontier, reaffirming its commitment to bringing professional-grade tools to sailors everywhere. With the launch of AI Polars, the horizon has never looked more clear and personalised.

Iridium GO! exec®

Boaters are subject to rain, wind, and extreme heat, so being prepared for the weather and keeping up with sudden changes is required. As technology advances, the PredictWind weather forecasting smartphone application and website has mariners dialed in when weather or cellular service start to adjust.

While technology grows, the boating community now has better resources at their fingertips, and PredictWind, a weather application, is one download all mariners should consider.

PredictWind— The Weather App for Boaters

When it comes to sailing, obtaining accurate weather information is vital for ensuring safety and comfort on the open seas. Fortunately, advancements in technology have revolutionised the way sailors access weather data, with satellite communication providers such as Iridium and Starlink leading the way.

Weather Forecasting Made Simple With PredictWind

This article explores the advantages of Starlink, a newcomer in the field of satellite communications, and the reliability of the Iridium GO! Exec device for offshore communications, specifically for marine weather data services like PredictWind.

Nautical Communication: Starlink and Iridium GO! Exec for Dependable Marine Weather Data

By John Hembrow - Down Under Rally.

As someone who is in regular contact with the owners of cruising vessels that undertake ocean passages, I have some concerns about what I see as an emerging trend with the advent of Starlink. There is no doubt in my mind that Starlink is the solution for sailors who are seeking to have affordable high-speed internet on their boats. However, I don't believe choosing Starlink as the sole method of communications whilst at sea is a prudent decision for several reasons, some of which are:

Should a vessel lose power (such as in the instance of a lightning strike or electrical issue), Starlink will no longer be operational, which in addition to the loss of the ability to communicate, will also result in no longer being able to access weather information.

Should those aboard need to abandon a vessel and find themselves in a liferaft, Starlink is not portable and, as such, will result in having no means of long-distance communication.

In the instance that Starlink is not operational, there will be a loss of real-time vessel tracking in many cases. See below.

As someone who actively uses PredictWind Tracking and monitors vessel tracking data, tracking provides a method to determine and monitor a vessel's position and progress. When an emergency/distress situation arises, the last know location or the vessel in distress needs to be determined by those responding. The more recent and accurate vessel position the tracking provides, the better the chance for SAR coordinators and other responders to determine the location of the persons/vessel in distress. In the instance that communications are not possible with the vessel/persons in distress, this tracking data becomes even more important, especially if the tracking can be maintained when/if the vessel is abandoned and the crew are aboard a liferaft by having the tracking device accompany them in the liferaft. It could be argued that activating an EPIRB would serve this purpose; however, an EPIRB provides no means of two-way communication with those in distress and those coordinating the rescue. Another consideration is the power usage of running tracking via Starlink with a DataHub. Although is it possible to do GPS tracking with Starlink via the PredictWind DataHub, the power requirements are large, and for this reason, on most boats, it is not possible to have Starlink running 24hrs a day.

If I chose Starlink as our primary means of offshore communications, I would also choose to maintain an Iridium GO! or Iridium GO! exec device. The Iridium GO! or the Iridium GO! exec provide redundancy should Starlink not be available for any reason and the ability to maintain communications should we need to abandon the vessel.

If using an Iridium GO!, we would opt for the PredictWind GO Unlimited Data Plan for the periods we intended to be at sea. The Go Unlimited Plan offers voice, unlimited data & unlimited SMS messaging, which provides the ability to maintain an up-to-date tracking page. If using an Iridium GO! exec combined with a PredictWind DataHub, we would opt for the GO! Exec Unlimited plan which would be our preference. There is the option to downgrade the plans and make some savings during the periods when we are not at sea/on passage.

We would also advise those with whom we lodge a float plan, such as Passage Guardian and AMSA, that we have an Iridium GO! as our backup and provide our Iridium/PredictMail email address, Iridium phone number, and our PredictWind Tracking Page URL in addition to our primary email address and phone number.

To appreciate the value of being able to maintain communication after abandoning a vessel, read the first-hand account of the owner/master of a vessel who was returning to Australia from Vanuatu when his vessel was lost. Among other things, the owner's account of the events includes details about how being able to maintain communications from a liferaft was invaluable.

https://www.downunderrally.com/news/loss-of-the-liberty

Read another first-hand account of a life raft evacuation by Craig Smith, a professional delivery skipper and Volvo Ocean Race veteran.



"Having been in the unfortunate position of hitting a submerged object which resulted in a Mayday call and eventual abandonment of the vessel, I will not go to sea without a communication device with a proven track record and the ability to work in a "dead ship" state. Water ingress can result in the vessel's power supply becoming redundant very quickly. For sure consider Starlink as a source of entertainment, for me, I will always have an Iridium GO! or the new Iridium GO! exec onboard period."

Press release - New models boost Weather Routing accuracy

PredictWind has a mission to provide the most accurate weather data on Earth. We are excited to announce three additions to our list of high-resolution Weather Routing models. As the leading source of trusted weather data and tools, PredictWind now delivers the UKMO 2km and Arome 1.25km weather models in Europe, and the NAM 5km model covers North America as part of our Weather Routing and Departure Planning tools.

High-resolution modeling provides more accurate and detailed forecasts in shorter timeframes. This means that using them in weather routing and departure planning can result in more accurate routes, especially in coastal situations. For racing sailors, this can mean winning race data. However, high-resolution models have limited forecast length and coverage area, which can be problematic for longer routes. To address this, we pair the high-resolution models with global models to provide full routes over any timeframe and geographic area.

The pairing of different resolution models is nothing new for PredictWind. We have been doing this with the high-res PWG and PWE 1km > 8km > 50km models for a decade. Now, the UKMO global 15km model will interface with the UKMO 2km model, the Arome 1.25km model will pair with the 9km ECMWF in Europe, and the NAM 5km model will pair with the 25km GFS in North America. This complex operation is seamlessly performed within the PredictWind weather routing engine adding no complexity for the user.

The process that PredictWind uses to calculate the Weather Routing and Departure Planning allows large high-resolution files to be used in every routing calculation. The routes are calculated in the PredictWind cloud, utilizing the highest available resolution and the most recently updated forecasts and ocean data. Since the heavy processing is done in the cloud, the transfer to the vessel requires a very small file size. This makes unparalleled data available on any connection type.

The new high-resolution models are available in the weather routing now. Maps are only available in the PredictWind App and Forecast website, GRIBs will be coming to the Offshore App shortly.

UKMO - NAM - AROME Weather Routing

If you have ever embarked on a sailing expedition, you know that the weather can make or break your voyage. Every sailor has stories of being stuck out in treacherous seas worrying about their safety. Of course, these precarious scenes can be avoided by employing technology.

Why PredictWind is an Essential Technology for Your Sailing Adventures

On our mission to provide the most accurate weather data on earth, we’re proud to announce a new addition to our list of high resolution weather models. UKV or UKMO 2km by the UK Met Office, delivers 2km resolution across the UK, Ireland and north-western Europe, to give you even greater forecast detail and accuracy.




UKMO 2km is detailed enough to forecast geographical effects along the coastline, such as funneling, thermals and wind shadows.




The UKMO 2km adds to the Arome, PWG and PWE high resolution models, so you can look for consensus across the world’s top four, high resolution models available. This combination is exclusive to PredictWind. 


UKMO Global model updates every 12 hours and the new UKMO 2km updates every hour. This is the highest update frequency of all our weather models. With hourly updates for the upcoming 12 hour period, you have almost real-time forecast data that is never more than 60 minutes old.

More accurate forecasts for Northwest Europe

Certain harbors are gathering places for sailors headed offshore. Back in the good old days I met a lot of fellow cruisers while arguing about the weather as we holed up waiting for a weather window to jump offshore. The sources of information were few — pretty much everyone shared the same data. Here in the USA the main sources were NOAA Coastal, Offshore, and High Seas text forecasts, gathered by weather fax, VHF and SSB radio. Sometimes we downloaded small-scale (large area) weather maps that gave us very general information on huge areas of ocean. And sometimes we just walked up to the weather station, as in Bermuda.

Juggling all the variables

PredictWind is a leading weather forecasting app designed for anybody who is out on the water. Using a unique combination of global and regional forecasting models, along with its own proprietary modelling, PredictWind gives you the most accurate weather data to safely and efficiently travel anywhere on open water.

Introducing PredictWind, Your Ultimate Sailing Companion

For people who love sailing, cruising, or any other water-based activity, understanding weather conditions can literally be a matter of life and death. In addition, being able to predict winds and other weather changes results in a more comfortable and often faster journey. The ocean is a terrific place to travel, but it can also be extremely dangerous for those who don’t take the proper precautions.

Planning the right weather window can save time, fuel, and most importantly, lives. In this article, we’re going to discuss the importance of understanding weather conditions when out on the water, with some tips that you should consider before any journey.

Boating and Weather – Key Safety Points to Consider

PredictWind, the leading provider of weather forecasting and routing services for sailors, has announced the launch of a new feature that will revolutionize the way sailors and yacht enthusiasts monitor ship and yacht movements around the world.

To ensure you do not miss these extreme weather events, we now have alerts on the forecast pages and a new GMDSS weather warning overlay on the forecast maps.

PredictWind now uses the following key indicators to alert customers of extreme weather events.

Tropical Cyclones Users are able to see these warnings throughout the PredictWind ecosystem. Forecast Tables:
The potential for extreme weather is shown in a new row called “Warning”. If an event is predicted, it is shown with a warning symbol. Daily Briefing: We now have a new field called Extreme Weather, and the relevant warning is displayed when these conditions are forecast. Forecast Maps & GMDSS weather warnings: You can now view the GMDSS (Global Maritime Distress and Safety System) weather warnings overlaid on any of our weather maps. The text forecasts are analysed in the PredictWind cloud using machine learning. Then each weather system, front and warning region is plotted accurately on the map, giving you a world-first, global view of the GMDSS forecast. Weather Routing:
In the weather routing tables, you will see the extreme events marked with a warning symbol. In addition, on the weather routing map you will also see the extreme events highlighted in orange, ensuring you are alerted to possible extreme weather events. The GMDSS overlay can also be displayed on the weather routing pages. The extreme weather feature, exclusive to PredictWind, has been created to give maximum safety on the water.

Press Release - 19 Augut 2022
The “Game Changer” for Weather Routing: Automatic Wave Routing.

PredictWind’s newest feature - Automatic Wave Routing allows users to see highly detailed wave data and how their vessel will perform in all wave conditions, along their route.

Weather Routing algorithms typically use wind and current only to calculate the fastest or safest route. However, the biggest factor for comfort and safety is the wave conditions. While the PredictWind weather router has always had the ability to input a manual wave polar, this functionality was rarely used. For most sailors, it’s simply too hard to predict their boat’s performance in all possible wave conditions.

We've made creating a wave polar for a vessel quick and simple. Using the boat's characteristics (beam, waterline length, displacement and draught) we create a hydrodynamic model of the vessel in all possible sea conditions. This data is then factored into the Weather Routing and Departure Planning tools, giving a more accurate and informative routing output to deliver a safer and more comfortable route.

Now that we know the boat's motion characteristics in all possible sea conditions, the boat's roll, vertical acceleration and slamming incidence can now be calculated. These important safety characteristics can be plotted to know exactly how rough it will be for the crew. A vast amount of modelling data is used to calculate these safety metrics, including wind wave and primary, secondary and tertiary swell. Normally this data simply cannot be downloaded on-board due to the large data size, but as the routing is processed in the PredictWind cloud there are no data constraints.

Users now have access to the following boat motion data:

Roll is the root-mean-square roll amplitude in degrees. When roll motions are large, moving around the boat and performing tasks becomes difficult. Objects not strapped down are likely to move. A roll RMS limit of 4 degrees is often used for safely moving around the boat and completing tasks. Roll tends to be the largest in beam seas. For sailing yachts, which have a heel angle, roll is the change in heel angle due to the waves.

Vertical acceleration is the root-mean-square vertical acceleration in G force. Vertical acceleration is a good indicator of the potential for the crew to get seasick. The higher the acceleration, the more likely the crew will get seasick. A vertical acceleration limit of 0.2g is often used for safely performing tasks and avoiding seasickness.

Slamming incidence is the likelihood of experiencing at least one boat slamming event per minute. For power and sail monohulls, slamming is measured 10% aft of the bow at the waterline. When this part of the boat emerges clear of the water and then impacts the water with a high relative vertical velocity, it is called a slamming event. For sailing catamarans, slamming is measured at the cross-deck structure and again is based on relative vertical velocity. For either monohulls or catamarans, a slamming incidence of 50% is considered excessive and may lead to hull damage or injuries to the crew.

This data is available in both the Departure Planning and Weather Routing tools. For Departure Planning, customers can use the wave data to find the best time to depart that suits their boat and crew's safety parameters. With Weather Routing, customers can use the wave data to either slow their boat to avoid adverse conditions or plot a course around areas with an unsafe sea state.

Automatic Wave Routing opens up a whole new world of detailed data, giving users confidence to make the right decisions for a safe and comfortable trip.

Press Release - AIS Vessel Positions 27 June 2022 - Immediate Release

PredictWind now offers AIS vessel position data, further enhancing boating safety for their users. AIS is a system where boats that have an AIS transponder installed can automatically broadcast their vessel identity, real-time position, course, and speed, using VHF frequencies. These positions can be seen and collected locally and via satellite. PredictWind sources this AIS data through our partner SPIRE; a market leader in satellite AIS vessel position data. This gives access to 280,000 vessel positions around the globe at any one time.

At home or in the middle of the ocean, AIS data via PredictWind allows you to see what vessel movements are happening in your area of interest. A key safety feature that PredictWind has developed is the ability to download AIS data via satellite connection. Until now, if you didn’t have a land-based internet connection, you could only see vessels on AIS that were within VHF range (20-30Nm). Using the PredictWind Offshore App, via a satellite connection, such as the Iridium Go!, you can download AIS data in a 300Nm range. This gives users the ability to view and avoid highly congested commercial traffic routes, fishing fleets, or simply be able to see if it is going to be a busy watch on deck.

Recognizing that the AIS network is a great safety feature, PredictWind developed AIS aggregation in their DataHub product. This means that the DataHub collects any AIS vessel data within range of your transponder, then sends this data back to the AIS network, further increasing the quality and safety of AIS data worldwide.

AIS vessel data is available on the PredictWind Forecast Website, PredictWind App or the Offshore App.

Press Release - PredictWind Departure Planning - Double the forecasting power 27 May 2022 - Immediate Release

PredictWind Departure Planning - Double the forecasting power

With advanced weather technology, there is no reason to get caught out in unfavourable weather conditions. PredictWind introduced the first online Departure Planning tool over a decade ago and now with new updates, it’s even more effective at finding the best weather window for departure.

Using the power of PredictWind’s Weather Routing, the Departure Planning tool compares four departure dates and associated weather conditions to enable you to make the best departure decision. A PredictWind weather route performs an incredible one billion calculations to remove all the “guesswork”, of “when and where” you will encounter the next weather system. By examining the four departure dates or times, and the four models, Departure Planning performs 16 billion calculations in the PredictWind cloud. This data is then summarised to ensure that selecting your departure date is both easy and stress-free.

Departure Planning has been upgraded with the following features:

Previously you could only compare two weather models at once, but now you can compare four models. This gives you double the confidence in your decision-making process.
