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.

Chana's Cafe Whitehouse Road, Woodcote

Low arched bridge, about 1.5 metre max above water level, permits only very small boats to pass under.

Could someone with local knowledge make corrections to the paths in this area? For example:-
(a) "Way: 27969965" is clearly not accurately placed and is misleading.
(b) "Way: 27969930" (ditto)
(c) "Way: 27969933" shown crossing the water near this marker, gives the impression it is not depicting a way!
(d) Maybe "Way: 35136434" is part of one of the above?
(e) There are other anomalies I have not listed here.
