Summary
An offshore wind farm crew transfer vessel avoided an anchored vessel in fog after radar did not detect it. The flash describes reduced speed, lookouts and sound signals, and recommends reviewing navigation risk assessments and small-vessel procedures, ensuring Masters understand radar settings and can confirm calibration using known objects.
