We are excited to introduce Power Routing, a completely new weather routing feature for Powerboats. This is unquestionably the most advanced weather routing feature on the market, and will transform the safety and comfort of your coastal and offshore trips. 

In addition to finding the most fuel efficient route, you can see key safety and comfort metrics like roll, vertical acceleration, and boat slamming.

The smartest powerboat routing on earth

Power Routing performs billions of calculations to find the most comfortable or the most fuel efficient route. Our new powerboat algorithm factors in wind and wave drag, and the world's most comprehensive ocean and tidal currents, to find the optimal route.

Enter your boats height, displacement, waterline length, beam and draught. This data is then run through aerodynamic and hydrodynamic modelling to calculate how your unique boat shape will interact with all wind and wave conditions.

The most fuel efficient route is the fastest and often the most comfortable route. Power Routing uses advanced hydrodynamic modelling of your boat characteristics, and the wind and wave forecast, to calculate the roll, vertical acceleration, and boat slamming that you’ll experience along the trip. This lets you know what’s ahead so you can take preventive measures, alter your destination or change your departure timing. 

Use the Departure Planning tool to find the best weather window to depart. The departure planning tool performs a weather route on 4 consecutive days (or departure times) to provide a simple summary and comparison of each departure date.

By selecting the best day to depart you can make significant fuel savings in addition to finding the shortest and most comfortable trip.

Power Routing works just like Google Maps. Simply slide the start and end points on the map, then tap the calculate button. The results are displayed on the map and table for your entire trip, so you can quickly see the optimal route and parts that are uncomfortable or unsafe.

Using PredictWind’s extreme weather warnings, get alerts for lightning, thunderstorms, fog, wind against current, and rain squalls. View the GMDSS national marine weather warnings on the map, along the entire length of your route.

The powerboat algorithm is designed for monohull powerboats from 7m to 24m in waterline length. In November 2023 Powerboat Multihulls will be added. There are no constraints on the cruising speed of the vessel, however, you are required to input your boat's most economic boat speed, economic RPM and corresponding economic fuel consumption for the algorithm to accurately calculate the most fuel efficient and comfortable route.

New Routing technology enhances safety, speed and comfort

We're excited about our role in shaping the future for sailors using Starlink and PredictWind. Alongside high speed offshore internet, it’s important to consider power, safety and redundancy with your communications system.

With the GO! exec and the new 5MB plan you can now run hourly GPS tracking 24/7 with minimal power usage. The GO! exec emergency capabilities keep you safe and give you peace of mind, in a package that is now more affordable than ever.



We’ve created an affordable GO! exec plan specifically for Starlink users.

Four features make the GO! exec with the 5MB Plan an unbeatable solution; emergency capabilities, low power usage, reliability and voice calling.


In a dead ship event such as a lightning strike, where the boat’s batteries are out of action, or a life-raft evacuation, Starlink will be of no use. The GO! exec’s backup battery could literally be a life-saver with 24 hours of standby or 6 hours of talk/data time. The SOS button is an extra safety feature for added peace of mind.

Starlink consumes a lot of power, so is not suitable to be used 24/7 on most boats.

For services like GPS tracking, AI Polars, and the PredictWind Anchor App that require a constant internet connection, the best solution is the GO! exec. This gives you the flexibility to only turn on your Starlink when you need high speed internet.

The GO! exec 5MB plan covers your hourly GPS tracking, AI polars and Anchor Alert monitoring without any data overages.

 is required for PredictWind GPS Tracking.

The GO! exec has an IP 65 waterproof rating, while the Starlink routers have no waterproof rating. The standard Starlink antennae only has an IP54 rating, which a source of potential failure in storms. Starlink does not work in heavy rain due to the K band frequency degradation in these conditions, where as the GO! exec’s L band frequency performs in any conditions.

In the event of a life-raft evacuation or medical emergency, make voice calls directly into the unit with no additional apps or devices requires. Be assured emergency services are aware of your situation and stay in contact until help arrives.

You may choose to use Starlink when at anchor, but use the GO! / GO! exec Unlimited Plan when on passage. This eliminates any power issues and also any potential overages on the Starlink mobile priority plans.

The perfect compliment to your Starlink

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.

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. The company's new real-time satellite and terrestrial AIS display offers users the ability to view vessel positions and movements anywhere in the world over any satellite connection.

The AIS data is available on the PredictWind website, PredictWind App, and Offshore App, and provides a wealth of information for sailors, yacht enthusiasts, and maritime professionals. The Offshore App is the world's first app to provide AIS data via satellite, allowing users to download vessel positions within a 300 Nm radius.

With the new feature update, users can search for vessels by name or MMSI number and add them to their favourites list, allowing for easy tracking of friends or vessels of interest. The real-time satellite AIS feature allows users to view any vessel anywhere in the world, while the terrestrial AIS provides land-based AIS position feeds.

The system identifies all vessel types and allows users to filter by vessel type, providing greater control over what types of vessels are displayed on the map. Additionally, users can view speed, direction, draught, destination, and ETA information for any vessel on the map.

PredictWind's CEO, Jon Bilger, said, "We're excited to launch this new feature, which will provide mariners with a comprehensive and accurate view of ship and yacht movements around the world. With real-time satellite AIS and terrestrial AIS, our users can access a wealth of information that will help them make more informed decisions about their sailing or boating plans and adjust accordingly wherever they are."

PredictWind has also taken the integration of the DataHub with the AIS network even further. The DataHub collects AIS data from all surrounding vessels and transmits it back to the PredictWind servers via the existing satellite/cellular connection, improving the quality and safety of the global AIS network.

The AIS data feed can also be shared via wifi to compatible devices or apps on board, such as the Navionics Boating App, and recorded to the DataHub's SD card. This creates an accurate log of all nearby vessel positions, which is crucial for an insurance claim in the event of a collision.

PredictWind's CEO, Jon Bilger, said, "The integration of the DataHub into the AIS network will enhance the entire AIS network making the seas safer for all. The ability to share the data feed via wifi and record it to the DataHub's SD card will also help sailors and maritime professionals in the event of an insurance claim."

The new features are available now on the PredictWind App, PredictWind website, Offshore App. DataHub features require a DataHub. Users can sign up for a free version or purchase a

Collect and Share AIS Data with the DataHub


 is a GPS Tracker packed full of additional features, including AIS data. The DataHub collects AIS data from all surrounding vessels and transmits it back to the PredictWind servers, via your existing satellite/cellular connection, to improve the quality and safety of the global AIS network. The data feed can also be shared via wifi to compatible devices or apps on board, such as the Navionics Boating App, and recorded to the DataHub’s SD card. Having an accurate log of all nearby vessel positions is crucial for an insurance claim, in the event of a collision.
