Lights at Sea 2.0

"Lights at Sea" is all about the lights serving as navigational aid at sea and their characteristics. With "Lights at Sea" you can

• teach and learn the international notation of light characteristics as used in charts and lists of lights,
• visualize the light patterns for a given characteristic or demonstrate them to your students,
• internalize important characteristics (e.g. the light patterns of cardinal marks),
• prepare yourself for the lights of a specific sailing area.

"Lights at Sea" is available on the App Store.
