Which of the following describes the typical size of life rings found on small boats?

The typical size of life rings found on small boats is commonly within the range of 2-20 inches. Life rings, also known as life buoys, are designed to be easily thrown to a person in distress in the water, and their size needs to balance visibility and floatation capability with manageability. A size range of 2-20 inches ensures that the life rings are compact enough to be stored on-board small vessels while still being large enough to provide the necessary buoyancy and support to help keep a person afloat.

In smaller boats, where space is often limited, life rings are designed to be light and easy to handle, making this size range practical for effective emergency response. Larger rings would be more suited for larger vessels or for different applications and may not be as practical for smaller craft.
