(USA TODAY) -- It seems we're a step closer to figuring out the mystery behind the "Google barge" floating near San Francisco.
Citing "multiple sources," local CBS affiliate KPIX reports the barge will boast a party deck and showrooms to market Google Glass and other gadgets.
But if you're thinking this means a shot at boarding the barge, don't get your hopes up. It will be invitation only.
The four-story barge was first discovered earlier this week, prompting a visit from the U.S. Coast Guard. However, the agency would not reveal any details about the barge.
A second barge has also been spotted in Portland, Maine. The contents of its cargo remain unknown.
Google was not immediately available for comment.
