Ocean of Intrigue - leans more into the mystery aspect of being stranded in the ocean

Grip of the Hand - leans into the aspect of "The Hand" pulling the strings on everything 

Gilded Prison - we're stranded out in the middle who knows where, but at least we have fancy food and toilet paper

Maybe once we unravel the story a bit more more creative names could be come up with. Like why are The Hand here? What do they want? Does someone on the ship have something special? How did they teleport us? Is the ship itself special? Maybe once we have a few more details a more significant title.
