Vessel lightscards COLREGs-72 for iOS

This application allows you to learn COLREGs (International Regulations for Preventing Collisions at Sea) navigation lights rules. The app is structured in a card format according to COLREG rules. The results statistics is saved by the program and can be reset to default when needed.

Understanding of COLREG navigation lights allows you to correctly estimate the position of the vessel, its maneuvering capabilities and to determine the nature of its work at night time and in poor visibility conditions.

The application will be useful to navigators and those who prepare to become one.
