I find that 

--generate-sea:multipolygon,extend-sea-sectors,close-gaps=6000 

always works for me or

--generate-sea=polygons,extend-sea-sectors,close-gaps=6000 

Most times works.

Just remember to include in the polygons file for the style  

natural=sea [0x32 resolution 12]
natural=land [0x27 resolution 12]

Maybe it's no-sea-sectors then...?
