The vid shows the stern swinging around to the left and pointing the bow directly pointing at the stanchion it hit. Why did the pilot go to hard right rudder and appears to aim the bow for collision?
I give up, why?
I think we all know the really reason.
Climate Change.
Sounds like more business for Hampton Roads and Norfolk, Va
To my embarrassment and astonishment, I learned that the Dali, built by Hyundai Heavy Industries in South Korea, meeting the designs of the owner Oceanbulk Maritime SA and ocean transport service Maersk:
https://en.m.wikipedia.org/wiki/MV_Dali
was “a single screw.” I incorrectly assumed at least “twin screws” - 1 port side plus 1 starboard side.
A single screw boat / ship / vessel is prone to the propellor “walking” (known as paddlewheel effect or asymmetric blade thrust) - partcularly when the vessel is set to run in Reverse motion.
From the rear view: A right hand prop rotates clockwise when the vessel is set to run in Forward motion . . . and counter-clockwise when the vessel is set to run in Reverse motion.
In Reverse, the stern of the vessel “walks” to port - to the left.
(In my previous considerations (twin screws), I imagined that, in Reverse, only the starboard prop was functioning during the emergency reverse. And thus, ONLY the right rear of the ship was pulling toward the rear.)
So, in the crosswind of 8 knots from the east “working” on the very high and large “sail” of the vessel+containers ship heading southeast, and now including the prop “walking” the stern to port . . . the FSK Bridge support was in the way.
The ship has 1 stern rudder, plus 1 bow thruster.
When in forward motion (”under way”) and very heavy, but single screw in reverse, the rudder is initially not a significant contributor. The bow thruster also not much help - if it was working.
Were these construction workers in the country legally?
I’m thinking it will only take a few weeks to clear the channel and traffic can start again, or am I wrong? Maybe this is not as bad as it sounds.
I dunno
I am bookkeeper for a construction company and we only hire Americans
I reckon I was assuming...
The container ship was being piloted by local pilots at the time of the collision, not its own crew, according to CNN. Local pilots, who are familiar with the harbor, are used to move cargo ships out to open water in hopes of avoiding accidents.
Also: The Singapore-flagged ship, called DALI is chartered by the Danish shipping company Maersk, the company told CNN. The ship was carrying Maersk customers’ cargo, according to the company, and was on its way to Sri Lanka from the Baltimore Harbor.

Dali sister ship: MV Cezanne:

See: https://www.marinetraffic.com/getPhoto/?photo_id=4950293&photo_size=800
MV Cezanne appears to have a single rudder. Ship, when light and high in the water - the single prop is more effective at performing the "prop walk" to port, when ship is in Reverse.
Thanks for the information.
Don’t be too embarrassed or hard on yourself...if you know the difference in ship handling that exists between a single screw vessel and a multi-screw vessel, then you are ahead of the game.
I haven’t had time to look at it in much detail, but I do appreciate the information.
It depends on if the can get a Competent trouble shooter with authority to cut thru the reams of red tape vs Woke bureaucrats and politicians who see an opportunity to “reimagine” Baltimore Harbor as a safe space for electric or sail boats and no bridges with no white people allowed!
Thank you.
Possibly, to check our response. Recon by fire.
Saw a boat captain say that at 6 to 8 knots, dropping anchor is as useless as a rider trying to stop a motorcycle going 100 mph with his boot.
Also he said he was surprised the anchor wasn’t ripped off the ship.
I saw that they were tugged to where they were before heading out to sea. It was after that things went wrong.
Yep. Lots of discussion on this topic on the forum. Tragic event.
