CBS and Mark Burnett are hitting the high seas, teaming up for a pirate-themed reality adventure skein as the studio has greenlit production on approximately 13 episodes of the untitled project, which begins casting shortly with an eye on a summer 2007 premiere. Details of the project are being kept under wraps.

What is known is that the action in the skein will take place on both land and at sea, suggesting the presence of ships and islands as central characters in the unscripted drama.

It's also expected the skein will incorporate traditional reality elements such as competitions and elimination ceremonies. (Perhaps losers will have to walk the plank?)

However, one person familiar with the details of the skein cautions the show will not simply be Survivor at sea, and will vary from Burnett's original Eye skein in many ways.
