It was a movie prop, not meant to sit out in the elements for years. It was falling apart and they finally dismantled it in November. When we were there the first weekend in December, the barge was sitting on the other side of the dock and a crew was ripping it apart. When we were on the Dream on January 22nd, it was completely gone.
I was never a fan of that ship being there, so I don't miss it at all - rather, I'm glad it's gone. But I do know that a lot of people loved it so it is a shame in that regard. Rumor has it that another pirate ship (possibly the Black Pearl) will take its place in the future.
