I committed r1746 to the coast branch.
The floodblocker rules which OSM elements are used to detect land and as 
sea areas can now be configured in the special style 
resources/styles/floodblocker.
If this style marks a ways as garmin type 0x01 the way is on land 
whereas 0x02 is used for sea. Now you can configure your own rules which 
tag combinations should be used for the flood blocking algorithm.

Have fun!

I have used it without problems, however currently all geofabrik extracts I had used (even Australia/Oceania or Lower Saxony) worked on the old version without problems too, while often these extracts caused severe flooding (haven't got any broken extracts saved however)...
Also not really sure if my command line makes sense:
generate-sea=--generate-sea=extend-sea-sectors,close-gaps=6000,floodblocker,fbgap=50,fbthres=500,fbratio=5

(until now I have been using: generate-sea=--generate-sea=polygons,extend-sea-sectors,close-gaps=6000 )

I think it is safe to commit the coast branch to trunk (and maybe include some defaults in the help file, especially I have no clue about a sensible fbration value), I could not note any problems.....
