Race Committee Timer


RC Timer

Race Committee Timer, RCTimer, is an Android application designed for race committees to do starts for sailing regattas. The timer can be set to a count down time, for example 5 minutes. It can also be set to a specific start time, for example 12:30. A sequence can be set so that multiple fleets can be timed in rotation, for example a start every 15 minutes. The timer can be started or stopped and minutes can be added. There is a reference page with signal flags and a lock button. The latest feature is that the app will now talk or sound a horn blast. Sounds can be programmed to occur at any count down time and anything can be said. A simple text file defines what is said or when the horns are sounded. The app is free. It is in the Google Play store under RCTimer.

How About for Racing

The very powerful sailing racing app is StartLine discussed in an article below. If all you want is a count down timer that can be synchronized to GPS time or to a signal from the committee boat, this app will work just fine. You can also program instructions to your crew or have the app call out the start sequence over your boats bluetooth sound system.

This is the main display showing 14 minutes and 57 seconds until the race start. The race starts at 11:00, which was the programmed start time. When this race starts, the next race sequence is started at the repeat interval of 15 minutes. The present time is 10:32:02. Sync will reset the timer to the nearest minute. This actually makes the app useful for racers as well as committees.

This is the Set Times screen where either a start time or an initial timer setting can be set. Which ever one was changed last will determine the mode of the timer. The sequence repeat interval can be changed to any number of minutes. Someone suggested allowing seconds and that can be done if this is a real requirement. Just ask but only if YOU need it.

Clicking Flags from the timer screen shows this reference page of the signal flags. It will rotate to fit the screen orientation.

RCTimer has text to speech and horn sounds built in. Any text editor can create the required file which is placed in the RCTimer directory on the SD Card created when the program first runs. The format is time in minutes:seconds followed by either nothing if you want a horn sound, or text which will be spoken at the desired time. This program is called TED for Text Edit. It is free from the Play store.

In the file shown in the editor, at 3:30 and 3:00 the text displayed (the time) will be read off. At 3:45 and 3:55 a horn will sound.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
