Bristol Bay fishing tools
SatChart
Offline maps, Radio Groups, tides, weather, logbook tools, and fishing research for Bristol Bay.
SatChart is designed for Bristol Bay commercial fishermen who need offline-aware map tools, group coordination, shared waypoints, location sharing controls, tides and weather context, logbook records, fish-ticket OCR support, and historical fishing analysis.
Field-ready priorities
Built for poor connectivity, fast decisions, and clear sharing controls.
Download map/data assets before heading out, coordinate privately with your Radio Group, and keep important safety limitations visible.
Core features
Radio Groups
Private group coordination with membership, shared pins, shared waypoints, and optional location sharing.
Location Sharing Controls
Live sharing is opt-in, can be stopped, and is intended for group situational awareness, not emergency rescue.
Waypoints and Pins
Local waypoints, shared waypoints, one-time location pins, and clear group visibility expectations.
Tides and Weather
Tide and weather tools for context, with reminders to verify official warnings and marine conditions.
Ocean/Satellite Context
Optional sea-surface temperature and ocean-layer context where available, with freshness and accuracy caveats.
Smart Logbook
Sets, deliveries, tender purchases, notes, receipts, and fish-ticket OCR support that users must review.
Deep Research
Historical charts, tables, district comparisons, date ranges, and export-oriented research workflows where supported.
Designed for review and trust
Built for field use
Practical workflows for Bristol Bay fishing operations and planning.
