Sailing Master M vs Live

Sailing Master M offers comprehensive sailing data and performance optimization information on iPhones, iPads, iWatches, and ActiveLook smart glasses. The application provides configurable pages and data displays, utilizing over 35 sailing measurements from the boat’s instruments, polars tables, and nautical charts. On phones and pads, the Data and Analog Displays can include minimum and maximum values and time series graphs. The Wind Display provides wind, heading, route, and speed information. The Route Display shows the expected wind conditions on the next legs. The Map Display shows the vessel with direction, tacking and downwind laylines on a nautical chart, or the wind laylines in another location. The connectivity is through NMEA 0813 Wi-Fi gateways such as B&G Vulcan, Zeus, GoFree, Yacht Devices, Signal K, Actisense, and ShipModul. The application has evolved from its initial focus on NMEA data display to encompass a comprehensive suite of features. Consequently, the app’s name has been revised from 'Display0183M' to 'Sailing Master M'. For further information, please refer to the user’s guide available on the app’s website or within the app itself.

Regatta Tracker turns your phone into a live GPS beacon on the water. Whether you're racing, cruising with your club, or on a private passage, simply join a session with a 6-character code and start broadcasting your position in real time. LIVE TRACKING See your speed in knots, heading, GPS coordinates, and accuracy at a glance. Your position is sent to the session organizer continuously so they always know where you are on the water. RACE & OFFSHORE MODES Switch between Race mode (high-frequency GPS, ideal for short-course racing) and Offshore mode (5-minute intervals, optimized for battery life on longer passages). BACKGROUND & OFFLINE READY Tracking keeps running even with your screen locked. If you lose signal, positions are queued locally and automatically uploaded the moment you're back online — no data is lost. MULTI-SESSION SUPPORT Join more than one session at the same time. Your GPS is broadcast to all active sessions simultaneously — useful when a boat participates in multiple tracking groups at once. SIMPLE TO JOIN No account needed. Enter your boat name, type in the session code your organizer shares with you, and tap Start Tracking. Password-protected sessions are also supported. Regatta Tracker is the companion app to Regatta Manager, a browser-based tool used by race officers, club managers, and event organizers to monitor their fleet in real time.
