I have a CC and a walkaround, and I don't leave anything valuable on either. There isn't much in the way of security when it comes to boats. Most locks can be broken with a screwdriver or a wrench. Sure, locks will keep the honest people honest, but they're not the ones you need to worry about. I've built a custom lock to go over the face of my electronics box to fend off the wolves, but I only use it when I'm away from the boat for a couple of hours.
