I have understood that it is a splitter problem, not a mkgmap problem. I 
do not know the splitter. How many nodes are there along the 
multipolygon lines? Any nodes relatively near to the tile border?

In Finland, I had a similar problem with Lake Päijänne, which is a 
single huge multipolygon. I have worked around this problem by moving my 
tile borders so that they do not cut through the lake.
