Mouse Instructions

  • 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.

Save/Load Instructions

  • 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.

Animation Instructions

  • 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.
