Really REALLY impressive.
I liked the ambientation a lot and the sounds of the sea/ship are a really cool addition, reminded me of the Patrician saga. The "chat system" also reminded me of the Mount&Blade series. Make a difference was a nice dejavu for me xD I love it even thought I lost all my money trying to bribe the guards and had to go on a trading journey hahaha.
On the other hand, I'd say controls of the ship need some work, I got stuck a few times, not sure if that was my fault though, I am really bad at lerarning new controls. But don't worry, this is just a tiny rough edge in a really good game.
