RaceTac Sail-Board

Add Boats by clicking the 'Boat:' pic in the controls. Add Marks by clicking the number.
Drag object by the letter or number to where you want them.
Double click boat to clone it (A1 A2 A3...). Double click a clone to remove it.
Click boat pic again to remove them and all their clones.
Single click a boat to select it for the controls. (Circle Shows on boat)
Use Boat controls to change angle (the slider) or Tack ('Auto' tracks the wind).
Use Mark controls to change type or show 'Zone' ring. Lines and Gates have two draggable ends.

You can Save a setup of Boats, Marks, etc. for re-loading later on.
To Save a setup, fill in a filename and click the 'Save' button at the top.
Saved files are always downloaded the way your browser handles downloads normally. Usually to a 'Downloads' folder.
To Load a previously saved file, click the Chooser button next to the word Load: (text may vary by browser). Then select from the file dialog.

You can animate the sailing of the boats through a path defined by the location of their clones.
Make one or more clones of as many boats as you want.
Position them along the sailing path.
The boat's heading will be along a line from the first one, through the middle of the clones, ending at the last clone.
You do not need to turn the boats to any particular heading if you don't want to.
To have them change tack according to the wind, set the boat's tack to Auto and add the wind arrow.
Click the Play button to start or pause the animation.
Click the Rewind button to stop and reset to the starting positions.
The speed between clones is adjusted so that all boats arrive at the same clone at the same time. So for example, regardless of distance, boat A and boat B will arrive at the locations of A1 and B1 at the same time.
