Display0813M is a customizable app for sailing data on iPhones, iPads, iWatches, and ActiveLook smart glasses. It offers configurable pages and data displays with over 35 sailing measurements from the boat’s NMEA network and polars tables.

On phones and pads, the Data and Analog Displays include minimum and maximum values and time series graphs. The Wind Display provides
comprehensive wind, heading, and speed information. The presentation is in a hybrid analog and digital format, based on the sailing context: going upwind, downwind, or towards a waypoint, and enhanced by the polar data. The Route Display shows the expected wind conditions on the next legs. On watches and smart glasses, the pages can be filtered depending on the sailing context, whether a waypoint is set or a polar table is activated. Display0813M connects to a NMEA 0813 Wi-Fi gateways such as B&G Vulcan, Zeus, GoFree, Yacht Devices, Signal K, Actisense and ShipModul.

The screen copies below (click to open) provide some detail on the functionality. For more information check out the user's guide User's Guide.

The iPhone and iPad app, which supports also Macs with Apple silicon, is available from the Apple App Store. Search for 'Display0183M' or use the link: Display0183M.

The app is delivered as recurring annual subscription (approximately 1€/$ per month), with a two week free trial, and runs on iOS 17 or later.

Summary

Fully configurable phone & pad Displays:
• Any number of pages, any number of rows on any page and any number of Displays on any row
• Any display type (Data, Analog Data, Wind, Graph or Route) in any location
• Automatic scaling. Displays adjust to screen: a single Display on a page fills the entire screen and all Displays on a page are fitted to the screen (limited by the smallest allowed text size). The Display sizes are relative to each other: XS is half of M, which half of XL.
• Page(s) Editor: change, add to or remove from the provided default pages or previous version’s converted pages.
• Display Attribute Editor: edit displays


Version 2.2

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.
• 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 message timeout: user selectable duration for received NMEA data becoming stale.

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”
• 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.


Next: Version 2.3 with Display Content Filtering now in testing
Each display can be filtered by sailing context:
• Beating or Not beating
• Navigating or Not navigating
• Polars or Not Polars
Please let me know (leave private message below) if you are interested in participating beta testing, or would like a preliminary version of the User's Guide.

Data & Privacy
Display0183M collects optionally logs (raw data, location and/or filtered and formatted NMEA measurement data).
The data is stored on the user device file system and never read or otherwise used by Display0183M. The user is responsible for managing the log files.
