App Description

This application with rotatable and zoomable interactive 3D models shows how the relative position of lights and shapes changes according to the bearing.
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
- 50+ cards with graphic representation on the front and solutions on the back for recognition of lights and shapes
