Which statement correctly identifies a Type IV device?

• A. A USCG-approved Type II personal flotation device
• B. One USCG-approved Type IV throwable device (ring buoy)
• C. A visual distress signal
• D. A fire extinguisher

Answer: (B)

Type IV devices are throwable flotation aids kept on the boat for quick rescue of someone overboard. They are not worn by a person; instead you throw them to the in-water person and, if needed, secure a line to help bring them aboard. The ring buoy is the classic example of this category, and that’s why describing it as a USCG-approved Type IV throwable device fits best.

Understanding the distinction helps: a wearable PFD (like a Type II) is something you put on, not throw. A visual distress signal is for signaling location, not flotation. A fire extinguisher is for fighting fires, not flotation. So the statement that identifies a throwable device aligns with the intended use and accessibility of Type IV equipment.
