Great weather App for boaters

Great weather app for boaters and doesn’t use huge chunks of data. Very data efficient (although there are other apps out there which are specifically designed to use even less data if you are intending to use Iridium satellite phone). Highly recommend this app for Cell and WiFi use.

Pocket Grib

We have been using this app for many years now in many different parts of the world during a circumnavigation. Generally it is accurate for a 5 day forecast, with the normal caveats when land can effect wind direction and strength.

Indispensable

Indispensable weather app. The local variations can be seen on the map view which is a great aid for interpreting the official sea area forecasts, and the graphical view identifies ‘when’ something will happen in your locality.
