The term “confused seas” describes a highly disturbed sea surface with irregular and unpredictable wave travel. For governments, industry, and people, COVID-19, unprecedented since the 1918 influenza pandemic, is synonymous with navigating confusion. For mariner at-sea training, it presents a daunting challenge. Modern training for licensed mariners benefits from simulators and classroom training at maritime academies, but hands-on at-sea training—for a minimum of 360 days—is irreplaceable. Just as no one would fly with a pilot who had never trained in the air and soloed, no ship operator would entrust a merchant vessel carrying passengers or cargoes to a third mate or third engineer not trained on board a ship at sea. It is unthinkable.
