I don't understand why we still need 0x4b polygon in case of using --generate-sea=polygons if we have a polygons for land and one for see. Isn't this enough?

The problem is that 0x4b behaves a bit strange, so I would prefer to neither map sea, nor land to it as in that case flooding or land over sea may happen. I think some people simply replaced 0x4b by other polygon types. Maybe we would have less problems if when polygons is used, no 0x4b background polygon were generated.

With all the excitement due to mp recently, I had completely forgotten
about this little addition to the sea generation code I did a while
back. It adds a new generate-sea option called close-gaps which
takes a distance (in metres). Gaps in the coastline less than this
distance, will be closed with a straight line. Not yet proven so please
test.

Typical usage: --generate-sea=polygons,no-sea-sectors,close-gaps=1000
