The lights and shapes permit identification of any ships encountered, determination of the route and establish rights of way to avoid collisions. The application is divided into 3 parts:
- Official text of the rules 
- 30 interactive 3D models with day and night views
- 56 cards with graphic representation on the front and solutions on the back for recognition of lights and shapes
