Lights and daytime shapes are very useful to recognise other ships and determine their route.
The aim of this app is to allow yachtsmen and sailors in general to extricate themselves among the regulations of the International regulation for preventing collisions at sea.
It is particularly useful for nautical schools and students who will soon take the exam to obtain a nautical licence.

The App is divided into 3 parts:
- official text of regulations
- more than 30 3D animations to understand the different rules, simulating lights' and daytime shapes' visibility from different angles
- multiple-choice questions (more than 3000 combinations) based on the 3D animations

Further characteristics:
- multilingual: Italian, English (soon also available in Spanish, French and German)
- customizable background
- customizable speed of 3D movement
