What must all vessels carry for emergencies, excluding personal watercraft and similar devices?

The correct answer highlights the importance of safety equipment required for vessels in Nebraska. In an emergency, having a bailing bucket is crucial for maintaining the buoyancy of a vessel that may be taking on water. It allows boaters to remove water from the interior, which can be vital to preventing capsizing or sinking.

Carrying a bailing bucket is a practical and effective means of ensuring that the vessel remains afloat in challenging situations, making it an essential item for safety on the water. Other equipment, while also important for various safety aspects, does not fulfill the same immediate function of water removal in an emergency.
