Which of the following is NOT a type of mark in the IALA Maritime Buoyage System?

In the context of the IALA Maritime Buoyage System, marks are used to assist in safe navigation. Each type of mark has a specific purpose related to the guidance of vessels.

Cardinal Marks indicate safe water and the direction of safe water relative to the mark. They use specific colors and shapes to convey information about navigational hazards and safe passage.

Regulatory Marks serve to indicate rules, restrictions, or information necessary for safe navigation, such as speed limits or areas where anchoring is prohibited.

Lateral Marks are designed to indicate the edges of channels and navigable waters, guiding mariners safely along a route.

The term "Static Marks" is not recognized as a category within the IALA Maritime Buoyage System. It does not refer to a distinct type of navigational buoy or mark, which is why it is correct to identify this option as not being a type of mark. Thus, understanding the established categories helps clarify the importance of the other options, while emphasizing that "Static Marks" does not fit within the recognized framework of the IALA system.
