Minko,

I will download your test data and give it a try.

If you want to get detailed information what the flood blocker is doing, 
you should enable an appropriate logging.
See 
http://www.mail-archive.com/mkgmap-dev@lists.mkgmap.org.uk/msg02381.html 
how the logging.properties file can be configured and add the line
uk.me.parabola.mkgmap.reader.osm.SeaPolygonRelation.level=INFO
to the logging.properties file.

You might also add the parameter fbdebug to the sea-generation options. 
In this case the flood blocker creates GPX files for each checked 
polygon and the pro blocking (highways) and the contra blocking (ferry 
routes) points. Opening these files with JOSM makes it easier to 
understand why the flood blocker fails.
