TackTracker Release Notes for Windows

Release 9.4.1 - 14 Jul 2024
  • Improve accuracy of leaderboard display for a variable laps race.

Release 9.4.0 - 30 May 2024

  • Add support for importing CSV track files from Vakaros devices.

Release 9.3.7 - 27 May 2024
  • Fix leaderboard display when handicaps in use and a boat did not start correctly.
Release 9.3.6 - 20 May 2024
  • Fix problem in reports not displaying elapsed times (since 9.3.4).
Release 9.3.4/9.3.5 - 22 Mar 2024
  • Fix a rare crash in the lap times report.
  • Republished as 9.3.5 on 2 May 2024 as build 9.3.4 was not versioned correctly.
Release 9.3.3 - 22 Feb 2024 Nav Rally fixes relating to the optional scoring settings.
  • Fix loading a Nav Rally event from the library when an optional scoring setting such as XTD is by default on (in Nav Rally Settings). The race would incorrectly assume the XTD value from the default setting, but the correct behavior is to use the race's saved setting. With the fix applied, the race will have XTD off if not saved with it turned on. You can turn on XTD for a race in the Rally Rules dialog.
  • Fix the rally results report, which was adding the XTD value twice to the total score.
Release 9.3.2 - 7 Feb 2024
  • Fix an anomaly in the Distance to Finish calculation which could occur when a boat does not complete the course.
Release 9.3.1 - 5 Feb 2024
  • Fixed handicap placings reported in an edge case where a boat's first track point is at the start
  • Interpolate the reported Distance to First place and Distance to Finish between track points. This fixes an apparent anomaly where a visually closer boat may a larger distance to finish.

Release 9.3.0 - 27 Nov 2023

This release brings a range of usability enhancements to the race editor to make the process easier and faster:

  • The Track Loader now lets you select by Date without first unselecting the "Show Just Loaded" checkbox.
  • Show only tracks travelled so far in the "Create New Races" dialog. This makes it much easier to find the start.
  • With multiple races, when selecting the next start time, we show only the track tails from the previous start time. This makes it much easier to separate tracks for each race.
  • When copy/pasting race editor settings, the race is immediately re-analysed to avoid the need to save and re-open the race.


  • Remember the selection for Name or Details mode. Previously, the user selection would revert each time a race is loaded.
  • Selecting a landmark in the "list nearby" view displayed an unrelated landmark.
  • Upgrade the background map to use the latest (version 3) HERE raster maps tile service.

Release 9.2.2 - 11 Nov 2023
  • Fixed a crash seen when loading a corrupted CSV file
  • Fixed a missing column problem with the nav rally results report when penalties are used.

Release 9.2.0 - 20 Sept 2023

General enhancements

  • Improved the color assignment algorithm when creating a race from loaded tracks. Will now preference bright and contrasting colors and try to avoid duplicates.
  • Fixed the color list box drop down, which was displaying multiple copies of each color
  • The help guide is now packaged as a PDF file, as modern Windows versions do not support .chm any more

Navigation Rally enhancements

  • Added a new scoring option to compute the gate penalty in meters. This is acheived by multiplying the raw time penalty by the boat speed (in m/s).
  • If boats are assigned judged penalties, the nav rally results report now shows an extra column for the raw score excluding the judged penalties, as well as the total score column.

Release 9.1.4 - 21 Jul 2023
  • Fixed a problem in which magnetic bearings would sometimes not be displayed even when the magentic bearing setting is checked.
Release 9.1.3 - 16 Apr 2023
  • Fixed a problem with the BL-1000ST upload driver that could cause a track to be truncated when automatically resetting after upload.
Release 9.1.2 - 8 Apr 2023
  • Fixed the magnetic bearing calculation used for Nav Rally.
Release 9.1.1 - 27 Feb 2023
  • Fixed some teething issues with the rally simulation.

Release 9.1.0 - 24 Feb 2023

Introducing some cool Navigation Rally enhancements - including a pre-race simulation!

  • A new button lets you create simulated tracks for your rally event - so you can simulate the event before it is run to see where on the course boats will be scheduled to pass each other. Use this simulation to identify and avoid dangerous situations ahead of time to ensure a safe event for everyone. Simulated tracks are not saved, and won't be created if you have real tracks in the event.
  • Add a new option for rally scoring: you can now select "Use fractional scores", in which fractional seconds early or late are included in the score.
  • The start gate is now locked at the start position - as moving this gate will generate invalid scores.

Release 9.0.8 - 9 Feb 2023
  • Fixed the Landmark Add button when a previous landmark was not selected.
  • Update security settings when communicating with the TackTracker cloud.

  • Added full support for the QStarz BL-1000ST logger.
  • Re-developed the Settings / Landmarks dialogs which are now much easier to use. The process to create a new landmark now has its own dialog and many bugs have been addressed.
  • Across the board button styling updates give a more modern look and better highlight the call to action for a dialog.
  • Simplified the Create Races dialog - removing the live race schedule component, which is better done in the cloud.
  • Fixed the Geo location search in the Add Landmarks and Create Races dialogs.
  • Navigation Rally:Fixed a problem in which the "Show/Hide Results" button would get out of sync.
  • Navigation Rally: Fixed a rare issue preventing a gate being inserted after the initial Gate A-A.

Release 8.5.8 - 13 Oct 2022

Update map API credentials.

Release 8.5.7 - 12 Jul 2022

Fix for the feature introduced in R8.5.6 to allow the use of '|' to share mark tracks. An unwanted extra mark is no longer created when the race is loaded.

Release 8.5.6 - 10 May 2022

A single tracker may be used to share mark tracks for multiple marks using the '|' character, where one of the marks is a start or finish mark or pin. For example, if the Start and Finish boats are the same boat, you can use one live tracker named "StartBoat|FinishBoat" to service both marks. Or you can name a tracker "FinishPin|C" to use the same tracker for the Finish Pin and mark "C". Note, this complements the support for the '&' character added in release Release 7.05.0

Release 8.5.5 - 21 Mar 2022

Two fixes specific to Variable Laps races:

  • Save the start and finish mark tracks if present
  • Fix a rare corner case where a boat was not correctly finished

Release 8.5.1 - 12 Nov 2021

Improve the smoothing of speed and VMG data.

  • A new rally setting checkbox lets you choose whether to show bearings as magnetic or true.
  • Regardless of the setting, you can enter bearings as either magnetic or true.
  • The Rally Course report shows the magnetic bearing for each turn
  • Fixed a problem loading Rally rules saved with a specfic rally event.

Release 8.4.6 - 12 Sep 2021

Move map tile cache from "Documents\My Tracks" to "C:\Program Data\TackTracker\". When Windows stores the Documents folder on OneDrive, deleting the map cache may have generated annoying notifications that many files were deleted. So we've moved the map cache out of Documents.

The Settings "Fixed Marks and Landmarks" tab has been renamed to "Landmarks" and the dialog has been redesigned to make it much easier to add and edit your landmarks.

A new location search feature lets you search for a place name anywhere in the world to locate your race or landmark and TackTracker will show the place on the map. And you can now add a Landmark and lay it on the map with your mouse.

When you select each landmark (and a race is not currently loaded) you will see the landmark shown on the map

TackTracker now offers a satellite map view - though please note that the service does not at this time offer high resolution satellite images outside of the US.

General Usability Fixes

  • All dialogs have been re-worked to display correctly when a larger (125%) Windows font size is used.
  • A redesigned license install process can now install licenses directly from an Access Code without the need to manually install a license file.

Race Editor

  • Changing the boundary times on the TimeSplitter is now easier - as you don't need to move the markers out of the way first.

Track Loader

The Cloud Get dialog has been re-designed to make it much simpler to find your tracks on the TackTracker Cloud. You can now make queries like "get all my tracks recorded in past 6 hours" and if getting your own tracks, it is no longer necessary to specify a location.
