Enough trial and error found me a solution to that. Bell shaking only registers when you hold the wii remote vertically, and thrust forward and back, NOT left and right.
I also had trouble with the fishing controls. Still have no idea how they work.
SPOILERS Boss 2
I died a couple of times fighting the ice boss. Apparently there are multiple ways the action can occur. Essentially, either Captain Rose attempts to flee and gets frozen, or she doesn't. I've beaten the boss if she doesn't get frozen, but can't win when she does. Ideas?
