Interesting that it was obviously timed to avoid taking it with any diver guests aboard.
The "one month" resolution prediction (estimate?) from the article- I have no idea if the writers were referencing the Updated Pirate's Manual 2.0 or not. There have been no recent reports in the media regarding her disposition, and as painful as that may be, it is not that unusual. To put a "time" on an incident such as this is foolishness.
This particular ship has undoubtedly proven to be a bad choice for piracy as most liveaboards, certainly those in this area, have little available reserve operating capital, the ownership is heavily invested in the vessel itself, not much spare change lying about to re-purchase their boat from the pirates. The crew sits in the same situation- their families can put no amount of money together that would interest the captor thugs.
If the pirates learned one thing, it is that their choice to seize the boat with no wealthy passengers aboard might have been a deal breaker. Recent piracy has centered upon ships of value, cargo of value, and crew of value (that is, backed-up by deep pockets). Sadly (?), none of this applies to the Indian Ocean Explorer incident.
Several of the various internet links to booking sites for the ship have been redirected.
