The last time I looked at the all-in-one (aio) styles, there was no land 
polygon defined in the polygons style (and I presume in the TYP file). You need 
this for --generate-sea=polygons to work correctly. See the documentation in 
the options file for more details.

You may wish to try --generate-sea without the polygon option (using the 
multipolygon option by default). The following works quite well for me:

 --generate-sea=extend-sea-sectors

(And by the way, are you sure you need to run splitter on the Canary Islands? I 
would imagine that the data is small enough not to warrant splitting.)

Cheers
