Because on our last sailingtrips every taverna offered free WI-FI for their customers,
it's easy to check the latest weatherreports etc.
I used the following apps on my Android-phone :
Apps for weather (free):
- Poseidon
- Meteo Sail Greece
- Windfinder
App for navigation (price ca. 20 Euro) :
- Navionics Marine Europe
Hope it's helpful,
Koen
