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.
