The original version of Hal was Hal's Race Results. This was an offline program that could be installed on a Windows computer from the Microsoft Store.
Hal's Race Results used old software technology dating from the year 2000. It has become very difficult to maintain, so we have been forced to discontinue it and remove it from the Microsoft Store.
The good news is that HalSail, the modern online version of Hal, can do everything that Hal's Race Results could do and more. You can take a file produced by Hal's Race Results and upload it to HalSail, whereupon all your data - including classes, schedule of races, boats and results - will be available online ready for use.
So if you are still using Hal's Race Results, now is the time to take out a subscription to HalSail.
