Yeah, - I've seen this on tv. Are they talking naked eye stargazing? Are large ships like that stable enough for telescope use? Maybe they put the ship on course with the rotation of the earth and do the "tracking for us"? :S I really don't know if it's a joke or for real. There must be some pretty dark skies out in the middle of the ocean, and a sturdy lounge chair with large binoc's might be just the ticket, - especially in the S. hemisphere where it would be a new sky for many of us.
