I guessed it'd sound that way when I wrote it, but I was in a hurry and I went with it. I've never had the opportunity to spend so much time out in the sea, for various reasons, but I've always like the aesthetic and general idea I have of what living at sea must be like.
There's also the fact that I'm a history aficionado and I really like things that transport me to times past. With all the history around the Caribbean about sailors, pirates, merchants and imperial powers, it's hard for me not to feel a connection to it when I do get to be at sea.
