Please could an expert investigate. It appears there are problems with (multi-)polygons right around Isle of Wight. Some GPS devices render large areas of the Island as water, especially at certain scales. The same problem is not present for the mainland to the north of Solent, ie it only exists on IoW.
It has been suggested that some multi-polygons may be broken, interrupted, corrupt, or other.
See https://groups.google.com/d/msg/osmand/YZtg8V3Nsis/D0M6aYRCCgAJ where there are example images.

If someone has the time, please fix the large offsets in this area.
