## What is GoAstern?

GoAstern is a sailing logbook and crewing app for skippers who want a single place to plan, run, and review every passage.

**Plan a passage**
- Drop waypoints by tapping the map or searching the catalogue of UK + NW European harbours and racing marks
- Drag waypoints to fine-tune the route; tag each as start / via / destination / hazard / escape
- Per-mark passing-side notes (port / starboard) and free-text approach notes
- Built-in tide forecasts (UKHO Admiralty for UK waters, WorldTides elsewhere) at every harbour, including secondary-port working
- Crew roster with optional Apple ID linking — claim crew members so each device sees the same vessel history

**Run a passage**
- Live GPS track recording, optimised for offshore use (background-friendly, force-quit-tolerant)
- Map shows planned route + actual track side by side, with deviation visible at a glance
- One-tap event logging: Tack, Gybe, Reef, Engine on/off, Sail change
- MOB workflow: bearing-and-distance tracker from the moment of trigger, anchored to the recovered position
- Garmin Connect IQ companion (sold separately, free): log entries and trigger MOB straight from your wrist

**Review a passage**
- Briefing pack PDF (skipper + crew sheet, route, tides, hazards, vessel + emergency contact info)
- GPX export for chartplotter import / sharing
- Personal logbook view shows every passage you've sailed across all your boats

**Crewing**
- Publish a passage so previously-linked crew can express interest in joining
- Skipper accepts / declines from the iOS app or the web (https://goastern.com)
- Crew automatically see briefing PDFs and tracks for passages they sailed

**Privacy by default**
- Field-level encryption for crew passport / DOB / address. Only included in briefings + shares when you explicitly opt in
- Account deletion wipes vessels, passages, profile, and contacts in one tap
- iCloud sync for your own logbook; opt-in crew sharing across devices

The app works offline — only sharing, push notifications, and tide forecasts need a connection. Made by sailors, for sailors.
