What is Weather Routing Vs. Vessel Performance Monitoring?

When I shifted from coast-wise to deep-sea one thing I noticed is the fisherman put a lot more trust in the forecasts than do the deep-sea mariners.

I recall crossing the Gulf of Alaska in the Aleutian freighter en route Seattle with capt Doug one time. He came up to relieve me and asked what’s going on?

I told him the wind had shifted to the SE and was increasing and the barometer was dropping. He told me that in 24 hrs we would be getting our asses kicked. He was right.

A few years later I was again crossing the Gulf of Alaska but this time on a 20 kt container ship. Same situation, wind shift to SE and increasing, barometer dropping.

Capt came up to the wheel house and I told him the situation and added that we were going to be into it later.

He told me I was wrong and proceeded so show me on the surface charts how the lows and fronts were going to move and how we were going to remain in good weather. I thought wow, these guys sure know their stuff!

Of course 24 hrs later we were getting asses kicked.

Lesson here is if they are not fisherman don’t listen to them, unless they show you the upper-air charts. If they are not using upper-air charts likely it’s bullshit.
