General
Categorys
- seamark:buoy_lateral:category=see table below
| Mark | Example Symbols | seamark:buoy_lateral:category | Where used |
|---|---|---|---|
| Port-hand lateral mark | port | Marks the port side limit of the fairway when heading inland. This will be towards the right bank. | |
| Starboard-hand lateral mark | starboard | Marks the starboard side limit of the fairway when heading inland. This will be towards the left bank. | |
| Preferred channel to starboard lateral mark | preferred_channel_starboard | Where the fairway divides either way around an obstacle, the primary channel is to the starboard side of this mark. | |
| Preferred channel to port lateral mark | preferred_channel_port | Where the fairway divides either way around an obstacle, the primary channel is to the port side of this mark. | |
| Right-hand side of the waterway | waterway_right | Marks the limit of the waterway closest to the right bank. | |
| Left-hand side of the waterway | waterway_left | Marks the limit of the waterway closest to the left bank. | |
| Right-hand side of the channel | channel_right | Marks the limit of a channel closest to the right bank. | |
| Left-hand side of the channel | channel_left | Marks the limit of a channel closest to the left bank. | |
| Bifurcation of the waterway | waterway_separation | Marks the conjunction of two waterways. | |
| Bifurcation of the fairway | channel_separation | Marks the conjunction of two channels within a waterway. | |
| Turn off at the right-hand side | turnoff_right | Indicates a turn off at the right-hand side. | |
| Turn off at the left-hand side | turnoff_left | Indicates a turn off at the left-hand side. | |
| Danger point or obstacles at the right-hand side | danger_right | Marks obstacles close to the right bank. | |
| Danger point or obstacles at the left-hand side | danger_left | Marks obstacles close to the left bank. | |
| Junction at the right-hand side | junction_right | Indicates a junction at the right-hand side. | |
| Junction at the left-hand side | junction_left | Indicates a junction at the left-hand side. |

Shapes
- seamark:buoy_lateral:shape=see table below
| seamark:buoy_lateral:shape | Definition | Rendering |
|---|---|---|
| conical | The upper part of the body above the water-line, or the greater part of the superstructure, has approximately the shape or the appearance of a pointed cone with the point upwards. | |
| can | The upper part of the body above the water-line, or the greater part of the superstructure, has the shape of a cylinder, or a truncated cone that approximates to a cylinder, with a flat end uppermost. | |
| spherical | The upper part of the body above the water-line, or the greater part of the superstructure, has the shape of a part of a sphere. | |
| pillar | The upper part of the body above the water-line, or the greater part of the superstructure is a narrow vertical structure, pillar or lattice tower. | |
| spar | The upper part of the body above the water-line, or the greater part of the superstructure, has the form of a pole, or of a very long cylinder, floating upright. | |
| barrel | The upper part of the body above the water-line, or the greater part of the superstructure, has the form of a barrel or cylinder floating horizontally. | |
| super-buoy | A very large buoy, generally more than 5m in diameter. |
Colour
There are two international buoyage regions, A and B, between which lateral marks differ. The buoyage region is encoded using the separate attribute "system" (MARSYS). Lateral buoys generally have distinctive shapes (can for port-hand, conical for starboard-hand) or may be a pillar or spar with distinctive topmarks. The buoys and their topmarks are always painted in red, green or red & green horizontal bands.
| Category (CATLAM) | Tags | Definition |
|---|---|---|
| Port-hand Buoy | seamark:buoy_lateral:colour=red - Region A seamark:buoy_lateral:system=iala-a |
Indicates the port boundary of a navigational channel or suggested route when proceeding in the 'conventional direction of buoyage'. |
| Starboard-hand Buoy | seamark:buoy_lateral:colour=green - Region A seamark:buoy_lateral:system=iala-a |
Indicates the starboard boundary of a navigational channel or suggested route when proceeding in the 'conventional direction of buoyage'. |
| Preferred Channel to Port Buoy | seamark:buoy_lateral:colour=green;red;green - Region A seamark:buoy_lateral:system=iala-a |
At a point where a channel divides, when proceeding in the 'conventional direction of buoyage', the preferred channel (or primary route) is indicated by a modified starboard-hand lateral mark. |
| Preferred Channel to Starboard Buoy | seamark:buoy_lateral:colour=red;green;red - Region A seamark:buoy_lateral:system=iala-a |
At a point where a channel divides, when proceeding in the 'conventional direction of buoyage', the preferred channel (or primary route) is indicated by a modified port-hand lateral mark. |
