PossoNavigare: a boating forecast with a verdict

Field notes

The proposed workflow combines vessel-specific limits with a route, date, and departure time, then weighs wind, gusts, significant wave height, period, current, visibility, forecast age, and official warnings. The example uses a Favignana–San Vito Lo Capo crossing and recommends returning by 14:30 as wind increases. The page also explains that individual waves can reach twice the displayed significant wave height and labels its sample data as fictional.
