Car Carrier lost control in Noordzeekanaal,

Car carrier VIKING SEA on Feb 17 went out of control in Noordzeekanaal, Ijmuiden, Netherlands, sailing upstream from Noordersluis to port of destination Amsterdam. The ship was pushed by strong wind, went off course, and though she managed to drop an anchor (or both anchors), she couldn’t come to full stop and ran onto the embankment of Kanaaldijk Toad at around 1340 UTC. (Though it was more of a contact, than grounding):

She was taken off embankment some 15-20 minutes later, and resumed sailing. She berthed in Amsterdam at 1530 UTC Sep 17:

Wind at that time was about 30-40 knots from the west.

That is sustained wind velocity.(??)
Gusts could have been a lot more.

Yes, sustained winds

43 Kn gusts, wind vel. appeared quite constant.

Forecast, not recoded wind gusts.
Forecast always “appears quite constant”, but are not always correct.

Gusts are far from constant, nor easily predictable due to local factors, like terrain, tall buildings etc. (OK, not too much “terrain” in this part of the Netherlands)

A good estimate on gusts over flat terrain is 30% above the sustained wind.
A sustained wind of 35 knots would produce gusts to about 45 knots.

That is as good estimate, guestimate, or “rule of thumb” as any.
PS> That part of Holland is definitely flat

From the site:
"The Ventusky application in itself doesn’t forecast the weather. We only visualize data from numerical models (GFS, ICON, GEM etc). "

It sets.
Could be a bit “Disney” but I’ve found the site thrustworthy.
