Well I don't see anyhow why cgpsmapper should be able to correctly 
render them. Anyhow the most convenient would be to have static osm sea 
only files, which are in such a format that mkgmap can use them easily. 
Then it would be just a matter of adding for each country the respective 
sea data (static) in osm format.
