Meaning and Definition
A maritime navigational aid that must be kept to the right side of a vessel when entering a harbour or channel from seaward.
In the IALA maritime buoyage system (Region A), a can-shaped, green, topmark (if any) buoy marking the starboard side of a channel. Its counterpart on the port side is a red, conical 'left-hand buoy'. The rule 'red right returning' does not apply in Region A; it is a specific regional convention.
Dialectal Variation
British vs American Usage
Differences
The UK (and most of the world) uses IALA Region A (green right-hand buoy). The USA uses IALA Region B (red right-hand buoy, termed 'nun buoy'). The TERM 'right-hand buoy' is standard in UK/IALA-A documentation but would be confusing in a US context without specifying the system.
Connotations
In the UK: Standard navigational term. In the US: May be understood but is non-standard; 'red nun buoy' or 'starboard-side buoy' (IALA-B) would be used.
Frequency
Common in UK nautical charts, almanacs, and sailing instructions. Rare in general American English; 'channel marker' or 'nun buoy' is more frequent.

Frequently Asked Questions
In the IALA Maritime Buoyage System Region A (used by the UK, Europe, Africa, most of Asia), yes, it is green and often can-shaped. In Region B (Americas, Japan, Philippines), the starboard-side buoy is red.
Yes, 'starboard-hand buoy' or 'starboard-side buoy' are technically more precise generic terms, as 'starboard' always means the right side of the vessel. 'Right-hand buoy' is a specific term within the IALA-A system's phrasing.
