small summary:

OSM = OpenStreetMap
OSeaM = OpenSeaMap
OSM is initially a pure GEO database with point, line and polygon objects to which certain properties ('Tags' or 'Key' = 'Values') are attached
from the geo-data 'tiles' are generated ('rendered' (raster-tiles) or (more modern) vector-tiles (often from third party service providers, according to personal taste or theme)
a map is assembled from these tiles and displayed (in the browser or in an 'app')
OSeaM uses the OSM database for objects tagged with 'seamark'
OpenNauticalChart (ONC, a group split off from OSeaM) renders a seamark overlay from the seamark objects
OSeaM provides the server infrastructure to serve this overlay and packages downloadable map packages for offline use
All three organizations offer websites, wikis and forums for information and further exchange (the latter may be more or less active):

The format is ISO/IEC 8211:1994, which is not free, but the IHO usage of it is described in the set of S-57 documents: http://www.iho.int/iho_pubs/IHO_Download.htm. It is necessary to read all the Appendix A & Appendix B documents, particularly the product specification as the format actually used in ENC equipment is a sub-set of the main standard. In addition the iENC product specification & encoding guide also need to be complied with: http://ienc.openecdis.org/?q=content/ienc-product-specification-24
