Drawing islands has been discussed from time to time on the forum, but I think the above pages and the idea you came up with about covers it. Maybe an annular water body is an improvement on the two water bodies hack.
Adding an -outline in or out option to a line effectively makes it a wall (the outside of a passage/scrap), so not what you are looking for.

Subject: [Therion] How to draw water area with an island
Is there a way to draw a large area of water, then draw an exclusion or island in the middle of it?
I drew some rocks in the middle of a water area. They partially block the water symbol - but not entirely.
I drew a border around the island area. If I use either -outline in or -outline out, then the entire area becomes opaque to everything. It is drawn like it is a column. If I do not use the -outline option, then it has no effect at all.
I also tried making the island border part of the water area. No change.
One way I can think of to do this is to draw the water as two areas, each of which goes half-way around the island. It would work but seems a bit complicated.
Suggestions?
