Race Committee Timer for Sailing race start timing.

There are two start modes. You can set a count down interval, for example 5 minutes. In addition, you can just enter the scheduled start time and the timer will count down toward that time. An interval time can be set in which case the start time will automatically increment by that number of minutes once the race start time counts to zero.

Here is a simple sound file. Modify to get what you want

3:30 three minutes thirty seconds

3:00 three minutes

3:45

3:55

5:00
