Display0183M
iOS Universel / Navigation
Display0813M is a customizable app for sailors for NMEA information on iWatches, iPhones, iPads, and Macs and ActiveLook smart glasses. It provides a selection of over 30 sailing measurements from the boat’s NMEA network and polars tables.
Each measurement has a minimum, maximum, and time series graph. The polars data is interpolated: instead of just the tabulated data points, also intermediate wind and boat speed data is available based on (bi)linear interpolation. The presentation can either be digital or analog.
The Wind Display has all key sailing information in context-aware analog format. It provides comprehensive wind and heading information in both analog and digital formats. It is based on the sailing context: going upwind, downwind, or towards a waypoint and enhanced by the polars data.
The Route Display shows the expected wind conditions on the next route legs, based on the current wind speed, direction and boat’s polars.
Display 0813 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, based on Vulcan 7FS data, wind direction, wind speed (both magnetic and true)
- MTW: water temperature (Note: value is red as it is, the Unit is always displayed °C)
- MWV: Wind speed and angle (both relative and apparent)
- 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

Quoi de neuf dans la dernière version ?
New capabilities
- Route Display: show expected apparent wind angle and direction on next route legs.
- Alerts: set a threshold for any measurement and create an alert when exceeding or not meeting this value.
- Trip GPS measurement: calculated trip distance for the current app session. Logs current, daily, and annual totals when closing the session.
- Wind Display: Course and Bearing to waypoint selectable between °M and °T.
- New measurement: Waypoint bearing °T.
Usability improvements:
- Analog Data and Wind Displays: Optionally smooth transitions between data readings. Consistent settings close dialogues for ‘discard changes and close’, ‘save changes and close’ and ‘change for this session and optionally save permanently’
- Embedded User's Guide (also available in Files/Display0183M)
- Designed for iPad: (Macs with M chips running macOS) window size setting.
- “Waypoint direction” has been renamed “Waypoint bearing”
- In case only either Magnetic or True value is available for Course or Waypoint bearing, the available value is used to calculate the missing value based on declination.
- Stale NMEA data timeout: user selectable duration for received NMEA data becoming stale.
- Error logging default set to warnings and errors instead of none.
- Added “New in this version” link to start page
- Time Series Graphs’ consistency
- Performance optimizations
Error correction
- Adding new or deleting old pages in Pages Editor activates the unsaved changes icon.
Notes: requires iOS 17 or later.
