Thanks for the info about the snail mail address.
I think I got my second question answered already, but what I was asking about was whether the ship needed to be under way in order for the cadet to do the sea project ("homework assignment" from the academy), not days at sea. I think the answer is "no" (correct me if I'm wrong). I was wondering if, since the ship assignment was made only 2 weeks ago, and the ship has been sitting in port since, with maybe another week before it leaves, if that will make it harder (or impossible) to complete the sea project. I think the answer is "no" as long as work on the project is done regularly, even when the ship is in port.
