The full picture before you cast off

Course, distance, arrival time, tidal windows, sunset — before departure you want it all at a glance instead of across ten apps. Voyage Briefing bundles trip planning into one overview, offline-first and without data harvesting.

Planned from start to finish

  • ·Draw your route right on the map — start, stopovers and destination
  • ·Leg overview with distance, duration and a continuous ETA chain
  • ·Weather, wind, tides, currents and daylight for every leg

Planned offline-first

Course, distance, ETA, sunrise and sunset and tidal windows are calculated on the device, even without a signal. Live weather is added through your own API keys.

A support tool

Voyage Briefing supports your trip planning — it does not replace official charts, the weather forecast or your own local knowledge.

Frequently asked questions
