What is one heavy‑weather routing adjustment for January North Atlantic passages that has consistently reduced slamming or fuel burn in your experience? How did you validate its impact with onboard or post‑voyage data?

In January, heavy-weather routing for North Atlantic passages can be optimized by adjusting a vessel's track to utilize prevailing winds and currents. Instead of following traditional routes, ships can employ advanced routing software with real-time weather data to navigate at a slight angle to the wind or take a southerly route to avoid severe conditions. This method reduces slamming and fuel consumption, as demonstrated by a shipping company facing rising fuel costs.
