In a Man Overboard (MOB / Hombre al agua) situation during restricted visibility or when the casualty was lost from sight some time ago, why is the Williamson Turn (Curva de Boutakow / Curva de Williamson) the standard recovery maneuver?

1. It brings the vessel reliably back along her exact reciprocal trackline (wake) on a 180° reversed heading
2. It requires the smallest turning diameter and stops the vessel within 10 meters
3. It allows the vessel to continue at maximum speed toward the nearest harbor
4. It automatically turns off the engine using satellite telemetry
