What is at 11.538911, 92.212003 ? It looks like they salvaged someones boat or a structure that’s pretty sophisticated? Or is there a secret hidout/den on the island and this is all a cover story to keep people away? /s
Looks like a derelict boat. It’s present in the 2011 image, but not the 2009 or 2008 images.
Tried using Google Map’s satellite imagery and they have the whole island blotted out. Bing maps also has it blotted out.
