Life Buoy & Rack
Contains two props: life buoy and a rack to hold the said item. I have no idea where this is in the game menu, probably somewhere in residential. Use a mod like Search Box Mod to find the prop (search for life buoy).
The thing in the middle of the life buoy is a container for the rope. In addition to the life buoy, the rack contains a red ladder that is used to help the person in water to climb out.
