Harbours, marinas and anchorages
Harbours, used by ferries and commercial shipping should be mapped using a node tagged with harbour=yes and the area of land used to support the harbour should be tagged as an area using landuse=harbour. Marinas, used by pleasure boats and yachts should be tagged with leisure=marina.
Piers against which boats can be moored should be tagged as (man_made=pier) together with mooring=yes/ferry/etc and, if appropriate floating=yes. Large piers can be tagged using areas.
It is also useful to mark anchorages. One can mark moorings seamark=ACHBRT, depth=* (in meter) and historic=wrecks. It is also useful to record nearby on-shore Amenities.

There appears to be no agreed and clear way of tagging navigation aids as yet (Feb 2012). The following is a summary of approved features, current proposals and older proposals.
- Approved features
- Current proposals
- Proposed features/Buoy
- Proposed features/INT-1
- OpenSeaMap/Seamark_Tag_Values
- OpenSeaMap/Lights_Data_Model
- Older proposals, possibly abondoned?
- Proposed features/sea mark (abandoned)
- Proposed_features/day_beacon (abandoned)
- Proposed features/navaid (seems to be inactive)
Coastline and islands
The coastline in OSM is a rich and complex environment consisting of many natural and man-made features. Tags relevant to marine mapping include natural=beach, man made=beacon, man made=breakwater, natural=cliff, natural=coastline, man made=groyne, man_made=lighthouse and natural=wetland. Other features on land of relevance to navigators include natural=peak, amenity=place of worship, man made=tower, man made=gasometer, man made=windmill, wind generators (power=generator + generator:source=*).
Presentation
The OpenSeaMap project provides marine navigation mapping based on these tags.

- World Port Index contains 4300 harbours in 400 regions. Every harbour has a 5-digit number as index.
