OK, I'm the first to admit I'm operating outside my knowledge comfort 
zone here.  But I've tried adding:

	--generate-sea=polygons,no-sea-sectors,close-gaps=2000

to the mkgmap command, and I've added:

	natural=sea [0x32 resolution 10]
	natural=land [0x27 resolution 10]

as the first two lines of the mkgmap "polygons" style file.

There's no improvement in the rendering of the ocean.

As I'm making a Garmin map which includes New Zealand, I had a look 
there.  The same problem exists - the ocean looks like land.
