StartLine is an Android application for use by people racing sailboats. It is not for navigation. Racing sailboats is inherently dangerous and should you decide to race, you are taking all responsibility for whatever happens. You can crash your boat or even die. It is up to you to make sure that doesn't happen. StartLine will not make it safer to race and in fact may make it more dangerous by helping you get to the same spot everyone else wants to get to thus increasing your risk of collision.

StartLine has no location data as part of the program and it is your responsibility to insure that any data you put in, either from a button push or a data entry, is accurate. Please be aware that even with accurate data, there may be and probably are errors in the program that may cause any given readout to be wrong.

By its nature, GPS position information will be inaccurate. If you use your phone or tablet built in GPS, the location errors will be so large that this program may be unsuitable for the application. Errors of 60 feet or more should be expected. With an external differential GPS connected by Bluetooth, these errors are approximately half.

The use of Bluetooth GPS units requires the use of a Bluetooth GPS interface program such as "Bluetooth GPS Provider." These programs can lose Bluetooth lock at any time, some worse than others. StartLine has no ability to deal with a loss of lock from the Bluetooth or internal GPS unit.

All readouts of direction to a mark are just that, the direction to the mark. They are not an indication of the direction your boat should go and in most cases you should not and can not follow the indicated direction due either to the wind direction or obstructions. StartLine is not for navigation, it is for racing.

StartLine should only be used after carefully evaluating its usefulness to your application in a safe environment such as a closed parking lot where you can walk around and get familiar with the program.
