The Cat I EPIRB is described as float-free and automatically activated. Which category does this describe?

• A. Cat I
• B. Cat II
• C. Class S
• D. None of the above

Answer: (A)

Float-free and automatic activation describes the Category I EPIRB. These beacons are mounted on a bracket with a hydrostatic release; if the vessel sinks, the beacon automatically detaches, floats to the surface, and powers up to transmit distress signals. This automatic activation is what sets Cat I apart from others. A beacon that must be activated manually lacks the automatic float-free feature, which would point to Category II. Class S is a different designation that doesn't specify automatic activation in the same way, so it doesn't fit the description as precisely.
