That's ok. Options are ordered and are valid only for the subsequent 
input file. So if you define the precomp-sea last it is not used for any 
of the tiles and does not show any sea. I think that's also the 
explanation for the other variants.

Mmh, I think I don't understand what you mean with "but not the other". 
Do you mean ways are shown only for the geographical tile (which I think 
is the 60923011.osm.pbf) but not for the grid tile? Does the grid tile 
have ways?

see answer to 1. Precomp-sea is not a tile/input-file and must be 
defined before any input-file.
