OOC: Yuriko will have set up a watch schedule, using at least two combat capable personnel at all times. Magical support is is short supply, so there were no considerations in that area. When the ship enters an uncharted sphere, the watch is doubled until the safety of the ship can be determined. A bell, or similar device (whistle, whatever) is either carried by the patrols or availabe on deck to signal a general alarm calling all hands. Anyone else have anything to add or change?
