Wind Coach vs SailViewer

Wind Coach connects to your boat's wind instruments via WiFi, giving you real-time wind analytics that help you make smarter decisions on the racecourse. LIVE WIND DISPLAY Stream true and apparent wind data from your YachtDevice YDWG gateway or B&G MFD over WiFi/TCP. See real-time speed and direction graphs with smoothing, trend indicators, and wind shift alerts. RACE-GRADE ANALYTICS Wind Coach computes the same metrics used by professional sailing coaches: - Detrended CSD: measures how shifty conditions are - Phase Persistence: how long shifts last before reversing - Phase Duration L/R: time spent in left vs right phase - Shift Trend: degrees per hour of persistent veer or back - Oscillation Predictability: how periodic the shifts are - Dominant Period: the rhythm of wind oscillations in minutes B&G MFD FILE DOWNLOADS Browse and download wind data files from your B&G Zeus chartplotter over WiFi/FTP. M2X ANALYTICS INTEGRATION Sign in with your M2X Analytics account to automatically sync wind data. Works offline - data queues while you race and uploads when you're back on internet. NETWORK SCANNER Auto-discover NMEA instruments on your WiFi network. Finds YachtDevice gateways and B&G MFDs automatically. Built by sailors, for sailors. Wind Coach is part of the M2X Analytics platform.

SailViewer turns sailing GPS and instrument logs into an interactive debrief on iPhone and iPad. Import a supported sailing file, choose the logs you want to open, and explore the race from several angles: • Track views with boats, courses, selections, and optional map backgrounds • Tables and graphs for comparing selected values • Polar analysis for speed and angle relationships • Start, Race, Boat, and Maneuvers views when supported by the data • Local image sharing from supported analysis windows SailViewer includes synthetic sample logs. Samples start closed, so you decide when to open them. You can import SW2, SLV, GPX, KML, NMEA, VTK, FIT, VKX, supported CSV sources, and supported ZIP archives. Your imported sailing files stay on your device unless you explicitly share them. Ordinary iPhones, including large iPhones, have permanently free local access and do not require weekly license checks. All iPads, including iPad mini, and this iPad app running on an Apple-silicon Mac are free through 31 December 2026. These devices require an internet connection for initial activation and at least once every seven days. Free access ends on 1 January 2027 at 00:00 UTC, when a paid subscription will be required. Purchasing will require a future app update; this release cannot take payments. There is no automatic charge. If access expires, your local library is retained. Optional error reports and usage summaries are off by default. Support reports are sent only when you choose to send them, and original sailing logs are not attached automatically. This is the new SailViewer app and is separate from the legacy SailViewer/TruSailViewer product. Automatic transfer from the legacy app is not promised; keep your original files and import supported formats into this app.
