Sailing Master M vs SailControl

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.

SailControl transforms your device into a professional-grade navigation and performance assistant. Seamlessly connecting with your vessel’s AIS and NMEA chartplotter, it brings your full instrument panel to your iPhone and Apple Watch. By combining real-time AIS target tracking, wind metrics, speed insights, GPS positioning, and onboard sensor data, SailControl gives you an all-in-one situational awareness solution - right in your pocket. Whether you’re a competitive sailing athlete striving for performance gains, a recreational sailor seeking safety and confidence offshore, or a professional mariner managing critical navigation tasks, SailControl adapts to your needs: - Sailing Races: Gain a competitive edge by tracking rivals in real time, analyzing their speed and course, and adjusting your sails or maneuvers with precision to outpace the fleet. - Recreational Sailors: Sail with confidence using clear visualizations of vessel traffic, wind conditions, and speed insights for safer, more enjoyable cruising. - Mariners & Captains: Enhance safety with precise motion telemetry, and situational awareness in challenging waters. - Vessel Spotters & Enthusiasts: Identify ships, monitor movement patterns, and log encounters with professional accuracy. - Marine Researchers & Surveyors: Collect reliable positional and telemetry data for studies, inspections, or field operations. - Coast Guards & Rescue Teams: Benefit from fast, portable vessel identification tools that complement onboard systems during operations. Built with SwiftUI and a modular real-time architecture, SailControl ensures seamless performance, high reliability, and a modern, customizable interface. From improving racing strategies to increasing safety at sea, it is the go-to digital cockpit for anyone passionate about the maritime world. To receive AIS and NMEA data, you need to configure the IP of your vessel’s AIS and NMEA chartplotter, SailControl Pro requires a subscription. A 7-day trial period is offered so that you can explore the PRO features. SailControl Pro includes: - Advanced vessel filters: search by name, MMSI, and more - Advanced NMEA instruments: Apparent Wind, True Wind, ARPA radar, Motion Sensors, GPS status - Unlimited “My Vessels” tracking: Add more than two(2) vessels to your tracking list - Map recording and Race data export: save and share your tracks, export time/laps as images or to Apple Health - Personalised settings: sort by distance, set max-distance filters - AIS/NMEA parsing controls: choose exactly which messages to process - Underway-only view: display vessels currently underway, to reduce lag in crowded areas - AI Bow Sentry (Experimental): Use artificial intelligence to analyze a live camera feed from your iPhone or an RTSP camera installed near the bow of your vessel. AI Bow Sentry assists in detecting potential obstacles and collision risks by identifying objects ahead of the boat and improving forward awareness. - AI Sail Trim Assistant (Experimental): Receive AI-powered sail trimming insights using your iPhone camera or an RTSP camera positioned near the steering area. SailControl analyzes sail shape and provides experimental recommendations to help optimize trimming decisions and sailing efficiency.
