This is an update to V21.

The latest version of ezTrap has two new functions along with minor cosmetic improvements.

  • The Trap6 course now has a template function that can be activated by the end-user. Each template has three generic Trap6 racecourses with different Target Race Times along with BRGs and distances for each mark;
  • All courses now have an ‘Export’ function that creates a separate Excel spreadsheet with the current Course Display. The exported spreadsheet can then be immediately sent to smartphones, printed, or further processed;
  • The Yacht Club course now has a provision for adding Port or Starboard roundings. Also, a minor bug fix that now allows a mark to be named ‘X’;
  • The Trap6, WL, and Opti courses now have the Wind-up or North-up course plot orientation options.
  • The User’s Manual has also been updated.

For more information on ezTrap please see the release notes on the download page

The new release was authored by Ed Bottrell who is phasing out his involvement with ezTrap. Huw Pearce will be providing end-user support and Jon Eskdale  technical support as needed. If you are interested in providing ongoing support or development, please let Huw and Jon know of your interest.
