Predict Wind: For whom smart weather routing with collision warnings is worthwhile
Predict Wind's DataHub introduces Over the Horizon AIS (OHA). This innovation promises a significantly earlier warning of possible collisions. Compared to conventional AIS systems, OHA significantly extends the detection radius and gives sailors valuable additional reaction time. The DataHub also generates polar data for the yacht. This data contains the expected boat speed at different wind strengths and wind angles and is an indispensable basis for weather routing. Cruise planning taking the weather into account is the core competence of Predict Wind. The app already contains polar data for many ship types. However, if data for your own yacht is missing, then installing the DataHub can be an important addition for precise weather routing.
Predict Wind DataHub: Collecting data for better cruise planning
OHA utilises AIS data available online to detect and interpret AIS signals far beyond the usual horizon. In an example scenario with a sailing boat travelling at 10 knots and an oncoming container ship travelling at 25 knots, the warning time is extended from 8.5 minutes with conventional AIS to an impressive 8.5 hours with OHA. This enormous time span should enable safer route planning.
The integration of OHA into existing navigation systems is straightforward. Users can display the extended AIS data directly on their chart plotter or in navigation apps.
Security has a price
An active Predict Wind Pro subscription is required to use OHA. This costs between 249 and 499 US dollars per year, depending on the package selected. The polar data function is only included in the most expensive subscription for 499 US dollars per year. Users also need a stable internet connection at sea. Starlink mini is particularly suitable here, with a monthly cost of around 150 euros, which guarantees reliable reception even in remote areas.
More on the topic:
It should be noted that OHA is not compatible with the Iridium GO! Sailors using this system must switch to alternative communication solutions in order to benefit from the advantages of OHA.
It is also questionable how useful the very long warning time of the Over Horizon AIS really is in coastal waters. This is because the shipping routes near the coast are hardly straight enough to accurately calculate an AIS target and a possible encounter over ten hours in advance. However, it can be a useful addition on long offshore passages.
Extended range of functions and polar data
In addition to the improved AIS functionality, Predict Wind now also offers the creation of polar data. This is particularly valuable for accurate route planning. Sailors can now estimate the theoretical speed of their boat more precisely under different wind and sea conditions. This enables a more accurate calculation of arrival times and helps with trimming.
The integration of polar data into route planning leads to more efficient and safer voyages. This can be a decisive advantage, especially for long-distance sailing or regattas. The combination of OHA and polar data makes Predict Wind a comprehensive tool for demanding sailors.
Predict Wind is not useful for all sailors
Investing in a Predict Wind Pro subscription and possibly in Starlink mini requires careful consideration. The added value may be limited in coastal waters. Offshore sailors and regatta participants, on the other hand, benefit considerably from the enhanced safety and optimisation options.
The costs are high, because in addition to the monthly subscription for Predict Wind, there are also the costs for a stable internet connection. Offshore, only a satellite-based system is an option. If satellite internet is already installed, this relativises the costs. The energy management on board must also be right, because the constant Internet connection requires a lot of power.
