Buoyage systems

The tags defined on this page will render in various nautical charts.

This page defines values for the "seamark:buoy_lateral:system" and "seamark:beacon_lateral:system" tags for lateral marks.

System	seamark:buoy_lateral:system seamark:beacon_lateral:system	Region	Colours
IALA-A	iala-a	World, except Americas, Korea & Japan	Red Port-hand, Green Starboard-hand
IALA-B	iala-b	Americas, Korea & Japan	Green Port-hand, Red Starboard-hand

Inland systems
