Sereno
Tools for cruising sailors, built and used aboard S/V Sabado, a Lagoon 42 catamaran.
Sereno Routing
Weather routing on GFS, ECMWF and AIFS, around land, reef and shallows. It plans a passage from two points and a departure time and reports the route, the conditions on every leg and a PDF. It's for planning a passage, not for navigating by.
It needs an access token. The Android app is under Settings once you're signed in.
Departures
Which day to leave. Every candidate departure is sailed along the passage by 82 forecast ensemble members, and each day gets GO, WARNING or NO with the reason on it.
In testing.
Sereno One
An anchor alarm and AIS collision advisor that runs on the boat, with its own alarm. The alarm doesn't depend on an internet connection.
In beta with testers.
