Which ever way you want. If you have a right hand prop then that's it. Can't get away from the fact that 2 will turn the same rotation. My life experience with that is my dad had a very good twin screw boat and he took a notion to add a center engine. We tried every combination there is with rotation and none really made a difference. He screwed up a really good boat.

Common up here on the lakes are single screw bulk carriers.
Interlake is building a new one and the first in 35 years. Twin
EMDs on a pitch changing single screw, with bow and stern
thrusters. Looks like only around 700 ft. We built a couple of
the 1000 footers here in Erie. Early season this year......

Dean just answered your question In post #259.
Another question that can be asked is on twin screw Push Boats, you have a right hand wheel and a left hand turning opposite directions.
the vast majority of inland vessels prefer the wheels to turn outboard. Although every now and then we get one in that has the wheels turning inboard.
As a note, most Harbor tugs have wheels that turn inboard.
How interesting’ and please forgive me as I was somewhat distracted at the gun show tending door and should have studied his post # 259 before I asked my long awaiting question, thank you again for pointing that out.

Leave thus to the authorities! In the first place, every ship in the world is required to have a caption on board as well as licensed first mate, anyone who has ever held a commercial license knows this much!
As for under power, it was till it lost power and the mayday was sounded! For pitty sake are the conspericy queens going to want an auxiliary powered vessel to accompany every ship in case it looses power unexpectedly!!
These nitwit ideas would cost consumers a fortune!
He'll this is like blaming if someone experiences a brake failure on a car it should be imprisonment and not a failure.
Far to many people are not responsible enough to comment on things they a little bit about, but instantly, blindly, and cluelessly screem conspiracy, and point fingers with no idea what they are even sticking their nose in,,,, and I'm not just talking about one response here, a Lotta keyboard clueless cowboys have made that obvious!

So...what is the additional cost of having a tug or multiple tugs per ship Into or from a port per ton?

Jackie an inboard turning wheel will suck the boat to the bank in the intracoastal canal. Most kort nozzle boats turn inboard. Almost all 5000 and up river boats have nozzles. An inboard boat will out shove an outboard boat.

That’s what I have always heard. It’s good to hear it from someone that really knows.
The vast majority of the boats in our area run the Intracoastal system. Very few have Kort Nozzles. When Kirby bought Savage Towing a few years ago, one the vessels they acquired was a 110 foot with nozzles. They are planning on taking the old 645 12 EMD’s out and replacing them with 3516 Cats With latest Tier specs. they will also remove the nozzles, change the shaft angle to swing about a 96 inch wheel.
It will be a good job for us.

I agree, and I do know a little about merchant ships and commercial shipping, and do not believe for one second this was a conspiracy.
For clarity, my post you quoted was simply answering a previous post asking if a pilot was on board.
My Facebook feed is full of the conspiracy folks, some I'm ashamed in as they're educated, reasonable folks. The rest believe in a flat earth...
Spent half my time on this rock making small boats go fast for the wealthier than me all over the west coast, inland and off shore. No, doesn't make me qualified for expert opinion, however I've seen a lot, been around many have an understanding beyond a quick Google search.

Being an Ironworker, I can assure you a crane and operator with an oiler, cost more than a 1k dollars a day, that tug is far more expensive, as is the licensed Captian, first Mate, and crew to legally run it. Being a USCG MASTER CAPTIAN, I can't tell you how much, but many thousands for a container ship its size. I assure you it's not cheap. Plus, then what if the container is relying on the tug for propulsion and steering and it looses its power. Kinda stupid to me.
You don't just fire up a ship that size and start steering or stopping it in a couple football fields when it's already moving!

9/11 was meant to cripple the US financially, terrorists learned that supply chain interruptions from the Wuhan flu were much harder for US citizens to deal with.

Yes Jackie, they don't understand what they are asking. As a low profile tanker that is only 300m long uses 4 tugs for docking alone! And with the cost in the thousands per piece, and differance in the size of the job, unlike these guys, I won't make accusations and throw out figures at random to satisfy an unreasonable question.
Most here don't understand the time, distance, or momentum of even a ferry. I doubt many here could dock my 32' single screw Charter boat in its slip let alone back it out, and definitely wont understand the differance between inboard and outboard steering. But throw around per ton as if they could imagine how much tonage we are talking here, or the amount of thrust to get a reaction from the vessel, as well as what the steering wheel actually does, very little! As I can't on a ship this size!
I am not a measly yipykia boater. But do hold the USCG MASTER Captians Lisence. Retired now, but I assure you people have no clue what there suggesting, or how expensive the fuel alone is with these vessel's, many that burn gallons per yards, let alone, cost per job!

You might know this, as you are “in the business”
Doesn’t New York Harbor require a Tractor Tug
On the Gulf Coast, Bay Houston, which is what used to be the old G&H towing service, has sort of a controlled monopoly on handling ships all along the Gulf Coast. I figure their Rates are pretty much in line with Moran’s, who has a similiar deal with the New York Harbor Authority.
As wildcatter noted, nothing is cheap about any of this. Add to that more ports are requiring what are called “tractor Tugs”, which feature huge 360 degree propulsion units under the vessel that enhance the maneuverability of high horsepower tugs immensely.
Is the cost of having tug assistance necessary? Ask the Key Bridge.

LOL, my wife is a conspiracy theorist. She came to me this evening while I was cooking dinner and showed me the Arkansas river barge accident. Thinks it's all a part of a bigger plot by our gub'mint.
She subscribes to the notion that a lot more bridges are going to fall before April 8th, when the full eclipse happens. Sheesh.
