Doulos is the world's oldest ocean-going passenger ship. It's now 95 years old. I remember visiting it when I was a little kid with my parents.

If you are looking for books to buy for children or Christian books, it's having a great great sale. Some last minute presents perhaps?
I think it's opened till 31 December 2009. For more info about Doulos, visit their website at www.omships.org
