Final answer:
The South Cardinal Mark is a navigational aid that indicates safe water to the south. It is characterized by a specific light sequence, top marks, and letter identifications.
- Meaning: It is a type of navigational aid used in maritime navigation. It indicates the presence of safe water to the south of the buoy.
- Lights: The South Cardinal Mark is characterized by a flashing light sequence of Fl (6 + 1 LFl) every 10 seconds. This means that the light flashes six times followed by a longer flash, and this sequence repeats every 10 seconds.
- Top Marks: The top marks of the South Cardinal Mark consist of two Apeks (upside-down V-shaped marks) placed vertically above each other, pointing downwards.
- ID Types:The South Cardinal Mark is identified by letters. These letters are used to distinguish it from other types of navigational marks or buoys.
Step-by-step explanation:
The South Cardinal Mark is a navigational aid that provides information to mariners about safe water to the south of a buoy.
Here are the characteristics of the South Cardinal Mark:
1. Meaning: The South Cardinal Mark indicates that there is safe water to the south of the mark. This means that ships can safely navigate in that direction without any hazards.
2. Lights: The South Cardinal Mark is equipped with a specific light sequence to help mariners identify it during day and night. The light sequence is Fl (6 + 1 LFl) 10s. This means that the light will flash six times, followed by one long flash, and then there will be a ten-second interval before the sequence repeats. This distinctive light pattern helps mariners recognize the South Cardinal Mark even in poor visibility conditions.
3. Top Marks: The South Cardinal Mark has two top marks, which are Apeks, arranged vertically above one another pointing downwards. Apeks are triangular shapes, with the apex pointing downwards. The presence of these two Apeks on top of each other helps mariners identify the South Cardinal Mark visually.
4. ID Types: The South Cardinal Mark is identified using letters. These letters are usually displayed on the mark itself and can vary depending on the specific location. Mariners refer to charts or other navigational resources to determine the exact meaning and identification of the South Cardinal Mark in a particular area.
In summary, the South Cardinal Mark is a navigational aid that informs mariners about safe water to the south of the mark. It is equipped with a specific light sequence, has two top marks in the form of vertically arranged Apeks, and is identified using letters. These characteristics help mariners recognize and navigate safely around the South Cardinal Mark.
