Doesn't hurt to be prepared. We always have a Go-Bag. A waterproof smallish bag with passports, reading glasses, waterproof flashlight, cell phone and any necessary meds. It sits right by the door. I don't fear that the boat will sink (that would make for a lousy vacay) but I am realistic that things happen and would rather have the opportunity to possibly have these things in an emergency.
