The life of a seafarer offers a wider variety of experiences. Adventure, seeing different ports, traveling abroad--all are aspects of the seafarer’s life. Hard work, being away from family and friends, long times at sea--all are what some might consider disadvantages. Add to that the fact that a seafarer would have to be very wealthy or willing to work long, hard hours for someone else in order to experience the life, and consequently would have little time to enjoy the experience.
The posters above make excellent points. The life of a seafarer is filled with adventure. However with that adventure comes danger. The danger can come drom the forces of Mother Nature or from the evil of man as the case of the Somalian pirates.
Always the sea is a formidable force of nature, and man cannot overpower it. Gales and such disasters are not to be ignored as a threat to being on ships. Added to this, after having read such books as "Moby Dick," for instance, one marvels at the aplomb and fortitude of whalers. Even the sailors in novels such as "The Count of Monte Cristo" in which the men were away for years at a time, and the owner of the ships did lose some at sea. In recent times, the tale of Captain Richard Phillips who was held captive by Somalian pirates for five days when his ship was boarded by these pirates at sea. It was only when the U.S. Navy Seals arrived, that Captain Phillips was rescued. So, there is always danger that accompanies the thrill of travel and adventure and gain.

Second, seafaring is also often connected to wealth, because of trade. Third, there is a sense of adventure with seafaring that is appealing. The downsides of seafaring are many.
