- GRIB Weather Forecasts are Inaccurate: Let’s Stop Navigating With GRIB
The marine weather forecast visible in all major weather services comes from satellite imaging. It is only a prediction, and is only updated every 6 hours. For wind direction it has an average error of +/- 35 degrees offshore, and even worse for future predictions and in coastal areas where the wind flows around landforms. The resolution from satellite imaging is also low, only telling you one wind direction for each cell, typically 15 x 15 nautical miles. But everyone knows that the wind is not the same everywhere within a cell that large.
- Lower Fuel Costs and Emissions With Crowdsourced Weather Data
When SailTimer’s crowdsourced wind measurements are applied in weather routing software, the arrival time can be calculated with more certainty. With actual measurements from other vessels rather than the inaccurate predictions from satellites, a ship can more accurately
calculate its arrival time in port. This allows the ship to reduce speed as much as possible, for lower fuel costs and
