If you're thinking about doing Seamester... you should do Seamester

SeaMester... where to begin?! I'd highly recommend this to anyone who has the thirst for adventure, but especially for those nautically/marine inclined individuals among us. It is a great opportunity for those who want to learn a lot about marine life, seamanship, and scuba diving, not to mention the various cultures you will visit.
There is something different about traveling to a different country by boat - a certain camaraderie you share not only with other sailors you may come across at a dock or marina, but also with the locals who share the love for the ocean that is a large part of their lives.
Definitely do this program if you want to get out of the norm and learn A LOT. You get out what you put into it, so be open to learning and experiencing new things!
