Vaaramerkkien

Vaaramerkkien (Finnish for "navigation marks") are visual aids used to guide mariners through navigable waters, particularly in areas where the natural features are not sufficient for safe navigation. These marks are typically placed on buoys, beacons, or other structures and are designed to be easily recognizable from a distance. Vaaramerkkien are standardized internationally to ensure consistency and reduce the risk of confusion.

The most common types of vaaramerkkien include:

- Cardinal marks: These are used to indicate the cardinal directions (north, east, south, west) and are typically shaped like a diamond with a letter inside.

- Lateral marks: These are used to indicate the edge of a channel and are typically shaped like a can with a colored band. Red marks indicate the starboard (right) side of the channel, while green marks indicate the port (left) side.

- Special marks: These are used for specific purposes, such as indicating the location of a hazard or a safe water area. They can take various shapes and colors.

Vaaramerkkien are an essential tool for safe navigation, helping mariners to avoid hazards and stay on the correct course. They are regulated by international conventions and are subject to regular inspection and maintenance to ensure their continued effectiveness.
