This could shiver your timbers.

A man claims to have seen a ghost ship in the waves of Lake Superior. Jason Asselin posted a video of what he saw on Youtube this week.

The video appears to show a tall, eerie image moving in the waters.

Jason wrote in the video caption that he took the video off the coast of Marquette, Mich. on Saturday. 

The video has nearly a half million views already - and the critics are weighing in.

Some say its a large lighthouse. Others say it's probably a specific type of mirage called a Fata Morgana, in which elongated images appear on the horizon.
