dan buoy
LowTechnical / Nautical
Definition
Meaning
A small, temporary marker buoy, often used in fishing or surveying to mark a specific position, such as a location for nets, lines, or a measurement point.

Common Mistakes
- Spelling: 'dan boy', 'danbouy'.
- Confusing it with a large navigational buoy or a lifebuoy.
- Using it as a verb (e.g., 'to dan buoy' is incorrect).

In professional jargon, it is sometimes used verbally (e.g., 'to dan-buoy a location'), but this is a technical back-formation. The standard noun form is far more common.
No. It is a low-frequency, specialized nautical term. Learners only need to know it if they are involved in sailing, marine professions, or reading specific technical texts.
