# Sailcasted — Celestial Navigation Training Platform

> Sailcasted is a celestial navigation training platform. Students enroll in simulated ocean passages ("traversées"), receive daily astronomical observations by email, solve sight reduction problems on paper, and submit their calculated position. The system computes the delta in nautical miles between the student's fix and the actual position.

## Key Facts
- Observations computed from USNO/JPL ephemerides (±0.5' accuracy)
- Supports HO 249, AP 3270, HO 229, and SHOM reduction tables
- 4-tier progression system (Beginner to Captain)
- Free passage available: Halifax → Bermuda (7 days)
- No software required — observations delivered by email
- Magic link authentication — no passwords
- Cohort mode for instructors
- Virtual Sextant PWA for real-time practice
