EPIRB sends information both via VHF and satellite. With radio there have to be another vessel or shore radio station in range.

Add to that commercial ships are equipped with transponders making their position known 24 hours a day 7 days a week. Also the private global communications technology available even to the lowest of crew members like SAT phones. Makes it hard to be sneaky
