The problem
Planning a passage is often a hassle
Juggling between 5 different weather sites
Windy, Meteoblue, Windguru... Each one says something different. In the end, you don't know who to trust.
Guessing your arrival time
You leave hoping to arrive before dark, but the wind dies in the afternoon and you end up motoring.
Losing access to info once at sea
No 4G 20 miles from the coast. You're left without forecasts, sailing blind.
