Well, first an obvious question: did you fix the output from the 
coastlines script? It seems to have a preconception that it is working 
mainly on land, and that every shape is a lake. (I think). This doesn't 
work so well for islands, where you have to invert every way that is an 
island.

It also produces gaps in its output.

It also produces duplicated nodes for each island, use the validator in 
JOSM to remove those.
