One of our favorite sites, Art of Manliness has posted a fantastic piece detailing How to Cross the Ocean on a Freighter.
This is something that I have thought about in the past, and heard about on different TV shows and such but had dismissed as something that was just myth. Apparently it isn't and it looks like it could be a really cheap way to have a cool mancation.
This great article outlines a bunch of the different myths and missconceptions about traveling the seas by freighter, including the fact that it isn't actually cheaper than flying somewhere. I guess that isn't so bad though since this would be your mancation, not just the transportation :)
