Generate clear course diagrams. Analyze with forecast wind and tides. Multiple organization members can access or edit courses.
When done, publish for RC and racers.

Use existing lists of government and race association marks, or add your own. Then the course editing form lets you define start, finish, and all intermediate marks. Define the rounding direction. Special treatment is provided for dropped weather and leeward marks, as well as gates and "passing" marks.
The integrated nautical chart lets you visualize the course and quickly spot dangerous buttonhooks or other course configuration problems. Set the wind direction, or use the forecast, to identify how much of the course is upwind, downwind, or just a reach.

A course analysis page provides details on each course for the specified weather conditions. A graphical readout of the tactical course content allows quick selection of suitable vs unsuitable courses. A comprehensive listing of ORC-issued race certificates allows use of their VPP data to forecast time on all courses for each selected boat

When you've completed your work, a clean final page provides word-processor-ready drop-in tables of mark definitions and courses.
In addition, you can direct participants to the final output page for their reference. It's important, of course, to assure that your Sailing Instructions remain consistent with the materials made available here!
