Auto bilge is a good idea, just function check it before each trip and still bring a manual pump incase the auto fails. The problem is if it does fail when needed, by time you realize there's a problem it may be too late.

A simple high water alarm at the bottom of your hull would alert you to a situation long before it becomes an emergency and give you time to correct the problem. I think I'd prefer that instead of the auto bilge and associated wiring and tubing in my hull.
