Lights at Sea

"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),
• and PREPARE YOURSELF for the lights of a specific sailing area.
