Graphical Analysis

• Full 3D environment view, free orbit/zoom camera, WebGL.
• Mast ribbon shows attitude and boat speed (highlights poor speed).
• Wind ribbon shows wind strength (highlights poor strength), and current tack bias.
• Velocity arrows show:
• Speed through water and true wind angle
• VMG and current tack bias angle
• Shadow arrow shows GPS reported speed and direction
• True wind line shows current true wind direction and strength.
• Real time manoeuvre losses and gains calculated and animated.
• Rudder data overlaid if available.
• Video upload and recompression, sync taken from in-camera timestamps.

• Zoom/Pan overview graph shows beats, runs, reaches and manoeuvres in one place.
• Upwind/Downwind values shown:
• True Windspeed
• Apparent Wind Angle
• Velocity Made Good
• Average wind angle shown on per-tack basis.
• VMG graphed against true wind angle both upwind and down.

Connectivity

• NMEA 2000 → Bluetooth 4 → Mobile App → Cloud
• NMEA 0183 → WiFi → Mobile App → Cloud
• Bluetooth gateway supports circa 200 messages/sec
• Mobile App for both iPhone and Android
• Upload to cloud over WiFi or mobile data
• Log import from B&G, Expedition, NMEA 2000 (CanBoat) and timestamped NMEA 0183
• Post-import source filtering for NMEA 2000.
