AFAIK, OpenSeaMap is dedicated rendering based on the same
OpenStreetMap database as the map of e.g. http://www.openstreetmap.org
The OpenSeaMap project also defines certain tags that are only used
for navigation on water. See [1] for more info on how it works.

So on one hand they are already combined (use the same database), but
they are also separate (OpenSeaMap provides their own rendering of the
data).
