If boating on a waterway that has VhF radio coverage why is VHF considered the best way to call for help?

VHF radio is considered the best way to call for help on waterways with VHF coverage because it provides clear communication over long distances and is monitored by the Coast Guard and other vessels. It operates on a dedicated emergency channel (Channel 16) that allows for immediate access to assistance. Additionally, VHF radiOS typically have a reliable range and can transmit distress signals, ensuring that help can be dispatched quickly and efficiently.
