tcSpeeds vs Display0183M Usage & Stats

Display0813M is a customizable app designed for sailors, offering NMEA information on iWatches, iPhones, iPads, and Macs, as well as ActiveLook smart glasses. It provides a wide range of over 30 sailing measurements from the boat’s NMEA network, enhanced by polar tables. Users can view these measurements in digital or analog displays , or on comprehensive Wind and Route Displays. The Wind Display presents all essential sailing information in a contextually aware analog format. It offers comprehensive wind and heading information in both analog and digital formats. The display adapts to the sailing context, whether you’re going upwind, downwind, or towards a waypoint, and is further enhanced by the polars data. The Route Display provides information about the anticipated apparent wind speed and angle, and the estimated length of the route, including the tacking required for the next route legs, based on the current wind speed, direction, and the boat’s polars. The summary displays the remaining route length, including tacking, and the estimated remaining duration, considering the polars target speed or a user-set constant speed. Context filtering allows you to enable or disable a display or line of displays based on whether navigating, beating, or the availability of polar data. Optionally, you can display the minimum, maximum, and time series graph and set alerts for each measurement. The app connects to a NMEA 0813 Wi-Fi gateway such as B&G Vulcan, Zeus, Go Free, Yach Devices YDWG-02 or Actisense W2K-1 . The supported NMEA 0183 sentences are: - BWR: Bearing and distance to waypoint - DBS: Depth below surface - DBT: Depth below transducer. - DPT: depth of water. - CGA: Global Positioning System Fix data - GLL: Geographic position Latitude/Longitude - HDG: Heading magnetic - HDM: Heading magnetic - HDT: Heading true - MWD: undocumented, wind direction, wind speed - MTW: water temperature °C - MWV: Wind speed and angle (A,T) - RMB: XTE, range to destination, bearing to destination, destination closing velocity . - RMC: Speed over ground - RSA: Rudder sensor angle - VHW: Water speed and heading - VLW: Distance travelled through water - VPW: Speed - measured parallel to wind - VTG: Course over ground (T or M), speed over ground - VWR: Wind direction (A), wind speed (A) - WCV: Waypoint closure velocity - XDR: air temperature (°C), water temperature (°C) and barometric pressure (mbar). - XTE: Cross track error The following data items ("measurements") are read from the NMEA data stream or derived from these and the boat's polar data.. - Waypoint bearing (WP brng, °M, °T) - Waypoint distance (WP dst, distance unit) - Time to Waypoint (WP ETE, h.s), calculated WP dist / WP VMG - VMG waypoint (WP VMG, boat speed unit) - Cross track error (XTE, distance unit ) - Depth (Depth, depth unit) - Heading (Heading, °M) - Heading (Heading, °T) - Course (Course, °M) - Course (Course, °T) - Water speed (Speed, boat speed unit) - Speed over ground (SOG, boat speed unit) - Water temperature1 (Water tmp, °C) - Air temperature1 (Air tmp, °C) - Air pressure1 (Air pre, hPa) - Wind speed apparent (Wind Spd A, wind speed unit) - Wind angle apparent (Wind ang A, °) - Wind speed true (Wind Spd T, °) - Wind direction (Wind dir, °M) - Wind direction (Wind dir, °T) - VMG Wind (calculated) - Latitude (Latitude, DD°MM.mm’) - Longitude (Latitude, DD°MM.mm’) - Water Distance after reset (Wtr dst, distance unit ) - Total water distance (Wtr dst T, distance unit ) - Ground distance after reset (Grnd dst, distance unit) - Total ground distance (Grnd dst T, distance unit) - Velocity made good towards wind (Wind WMG, boat speed unit) - Heel (Heel, °) - Rudder (Rudder, °) - Boat target speed through the water (based on current polar table) - Boat speed of target speed (%) - Beat VMG boat target speed through the water - Run VMG boat target speed through the water - GPS based trip distance - Leeway (Leeway.°).
