"As a professional navigator, I need more than just basic wind speeds. The depth of data—from HRRR models to vertical vorticity—is incredible. The isochronal routing solver is robust and helped us shave hours off our last transit while maintaining a safe sea state."

Description

LuckGrib is a fully featured, easy to use, fast GRIB reader, viewer, downloader and weather router. Remote access to weather data via satellite. Advanced weather routing capabilities, for sailors, is available. Weather forecast data, packaged as GRIB files, can be downloaded directly from the LuckGrib server cluster. Downloads are available via: a direct high speed internet connection, or through the Iridium GO! as well as through the RedPort Optimizer. For sailors, LuckGrib offers a best-in-class, complete solution: industry leading visualization and ease of use, highly optimized weather data downloads via satellite, along with industry leading optimized weather routing and route analysis. Inshore sailors may not require satellite downloads, but will benefit from the rest of the system. LuckGrib is unique among apps that were originally designed for sailors, in that the weather analysis tools are powerful enough to attract attention from meteorologitsts. For sailors, meteorologists, and all weather enthusiasts, LuckGrib offers access to a wide range of high resolutions models, a number of global models, weather data at the surface, 850mb, 500mb and 250mb levels, parameters ranging from simple things such as wind, pressure and temperature, to more advanced quantities such as simulated radar, standard deviations, precipitable water, lightning, vertical vorticity, helicity and more. LuckGrib is a thoroughly modern and advanced GRIB viewer. LuckGrib provides access to many weather and ocean models, including global models such as GFS and ECMWF along with many high resolution models, which vary according to the region you are interested in. In the USA, there is the HRRR, NAM, NBM and many others. In Europe there is Icon-EU, Arpège, Arome, the Danish DINI and others. There are several ocean current models, such as the global RTOFS and Mercator Ocean, along with regional higher resolution models such as OFS, NCOM, CMEMS and others. The LuckGrib weather routing system is an industry leading, high quality, robust, high performance and comprehensive system. The LuckGrib isochronal Weather Routing solver has many unique features, such as being able to respect constraints (points that must be left to port or starboard,) deal with routes which require you to heave-to, outstanding visualization and interactivity features, and much more. LuckGrib comes with a 14 day free trial, or free access to reduced resolution downloads (LuckGrib Lite) for users who do not require access to the most accurate data. If you are interested in studying weather and gaining access to detailed weather forecasts, download the app and give it a try. Downloading data via satellite requires the Offshore Data in-app purchase. Access to the isochronal weather routing system requires an in-app purchase. Note that LuckGrib does not use a subscription pricing model - after the free trial, when you decide to purchase the app, there will be a one time charge, not an ongoing subscription.
