I'm new to 7th sea (but experienced GM otherwise). My players want to be crew members of a ship, so it looks like our adventures will involve a lot of sailing and ships. But, since I'm new to the game, I don't really understand how naval combat works. Can you give me an example, round by round? I get it that the ship's pilot/captain can spend their raises on negating damage (which represents clever sailing etc.). What about other PCs? And crew?
