Looked into it last year out of curiosity (and my boyfriend is terrified of flying). No less cheaper than flying, unless you plan on staying on the boat for a good amount of time. Most prices included sharing meals with the crew, a fairly good sized room compared to cheap passage on a luxury liner of equiv. or lesser price, etc. I seem to remember that such a voyage would've taken a but too long to do something transatlantic than the 2 weeks we had originally planned on. We are both back in school after losing our jobs, so maybe we'll consider it over a semester in the future. Would love to hear about someone's experiences.
