The actual report is quite good.[1] See especially page 26, the text that is underlined, in bold, and repeated in the executive summary. "After the wind had increased, the pilot was issuing more helm orders to the helmsman. These were either for hard to port or for hard to starboard, with few midships or lesser helm orders in between.
The pilot did not give the helmsman a course to steer, only helm orders".
That's the view from Panama, which puts a huge number of ships through channels narrower than the Suez Canal.
Fortunately, in the aftermath, the wild ideas proposed for getting the Ever Given out unstuck were ignored, and Smit Salvage, which is a very cautious outfit, was brought in.

This, taken together with the pilots speaking Arabic to each other with the bridge staff being unable to follow the discussion, gave me an impression of a very chaotic situation leading up to the grounding. Fortunately, it only caused material damage. Similar situation on an airplane would have been disasterous.
Captains are basically screwed in these situations as the ship responsibly falls on them but if they intervene or interfere with the pilots responsibility falls on them.
It’s a catch 22 and he probably should have demanded tugs but then he’d be in trouble with the bosses for costings.
Do it fast do it cheap and don’t fuck up.

Does anyone know what consequences the Captain of the Ever Given has actually faced?
> Addressing the language barrier, the report states: “Language difficulties can also add to problems associated with pilots and these should be considered. In the case of M/V EVER GIVEN, although Pilots orders were given in English language, the discussion between them was always in Arabic language, therefore the Bridge Team, could not understand pilots concerns (if any), the potential hazards, in order to on time and effectively conduct risk assessment.”
Having worked in a multinational company where many people speak other languages than the offical language I have noticed that people often don't realise how important it is to understand why they came to a decision. They'll discuss something in a second language then say the outcome to everyone. Often people don't want to make a fuss and ask how they came to that conclusion and important information is kept from the team. I've seen the issues this cause on non important issues in tech. I can't imagine how it feels when it comes to important things where people's safety is involed.

That's not really specific to the language barrier though. Anything discussed verbally will be lost to those who are not present, irrespective of discussion language.
Ticket with motivation, proposed solutions, considered alternatives, links to larger context. That should be the standard for many processes.
Though probably not for steering a boat, which has some real-time constraints.
ah yah, if there was a wrong detour along the route to the conclusion or something was incorrectly assumed, some bad premise relied upon, those junction points for interjection are all inaccessible when they unfold in an non-official language.
I think there are a lot of take home messages here that are applicable to many different situations.
1) Have a plan and try to stick to it. Rapid changes (hard port/hard starboard) without having a heading is dangerous.
2) Relying on local pilot/expert knowledge is important, but the captain knows their ship better. The expert should be considered an advisor and shouldn't be giving direct commands (especially without rationale). Experts can be wrong, so don't blindly follow their recommendations.
3) Communication is critical. The language barrier between the pilots and the ship's crew was pointed out repeatedly in the report. If you can't understand the rationale for a decision, blindly following it puts you at risk. It is important that everyone is communicating in a way that the whole team (pilot + ship crew) can understand.
4) The strong, changing winds were a known entity before the ship started the canal transit. Sometimes the risk isn't worth risking the whole ship and delay is warranted. Related -- don't be afraid to ask for help. Tug assistance would probably have made this crossing much less eventful.
I very much view this incident through the lens of the XY problem[1] ... don't ask me how to do a solution. Instead, tell me the problem or what you are trying to achieve, and then we can figure out the best solution to a problem. In this case, the pilots kept telling the helm to steer hard to port/starboard. This made it difficult for the ship's crew to achieve the actual goal -- keep the ship in the middle of the canal.

It should also be noted that this is the Panama Maritime Authority's report (the country the ship is registered in). The Suez Canal Authority had their own assessment and didn't participate in this one at all. The initial SCA comments blamed weather and visibility for the grounding. Later they blamed the captain entirely (for too many commands, ironically). There is a lot of money at stake here, so reader beware.

Tugs would help, but shipping lines don't want to pay for them. If the master orders a tug for the Suez Canal transit then he might be out of a job.
Hindsight being 20/20, using tugs would have been the cheaper option here.
My guess is that there is now a different cost/benefit calculation for super large container ships traversing the canal during high wind conditions. Or at least, I hope there is.

A bit off-topic, but it is refreshing to see a news article that can be bothered to link to the full report!
It is a news article on a site for the maritime industry... With that audience, there is probably an expectation to link to the actual report. I wouldn't have that expectation for a mainstream source (CNN, NYT, BBC, etc...), because that's not the audience. gCaptain's audience would have much more interest in reading the report directly (and be experts enough to interpret it).
I'd also expect a tech site like ArsTechnica to link directly to a security CVE. Same concept, different audiences.

If it doesn't link to primary sources, it's propaganda, not journalism. What's sad is that the word "news" now primarily refers to the former.
The Panama Maritime Authority made several recommendations, including... paying attention during transit.

I've seen the wind cited as a Black Swan, but I think it's really a known unknown. You know there can be high winds in the desert.
As for visibility: I'm not on the scene, but one would think that, with all the money at stake, the canal and the ships would have enough instrumentation that visuals are completely unnecessary.

Note the radar screens present in the report, I don't know anything about marine operations. So while I don't think you would want to navigate via radar alone, it looks like it has enough resolution that you could.
We dont have fail safe sensor technologies for cars, so I dont think we should expect to have it for ships that have even a greater need to know things in advance.
I was just thinking about knowing how far you are from the banks. Surely that's a solvable problem. It has nothing to do with knowing things in advance.
I'd suspect the issue would be with precision. GPS, et al. are good, but at what resolution do you really need it to be? Is 1m accuracy enough? 1m at what point on the ship? And do you want to install that equipment on each ship traversing the Suez Canal?
It was pretty clear from the report that they had a ton of data about the ship's speed, position, rotation, etc. It was quite detailed, not knowing where they were wasn't the problem.
The report also showed how much the wind was changing directions at the time. It was all over the place. Again, it was a known factor, just not given the appropriate weight.

LIDAR is cheap enough to put on a consumer car, so I really don't think expense is an issue. It wouldn't be GPS.
Not to mention the ships most likely already have transponders.
So it does seem like a "You're getting too close to the bank!" alarm should have been screaming at them. And probably was. Not responding properly was the issue.

How far away does LIDAR work? These are huge ships, pretty far from the banks, and the required positions within the channel locations would vary heavily throughout the trip (and probably even change day to day).
From the report though, you’re right that it seemed liked they already knew where they were in the canal with enough accuracy to know they were in trouble.

They use Lidar to map jungles from airplanes, so the range can be pretty far. I'm not sure what the relationship between resolution and distance is though. I'd assume it's inverse square combined with the Raleigh criterion, or something like that.
I'm going to have to research it more though.

I’m surprised that ships still rely on so much manual navigation. In 2023, when most of the aircrafts are pretty much handled by the computer, why are ships not working with same amount of automation? Pilots and captains should only be present to handle difficult maneuvers and emergency situations.
Pretty much all ships have some form of auto pilot suitable for the open ocean, but navigating the Suez Canal is an incredibly tedious process due to how narrow it is.
During the original Suez blockage news cycle, some maritime experts pointed out just how absurdly stressful it is to navigate a canal:
> [Captain Bill Kavanagh] said: “The procedure is very stressful for the ship. Those ships are on the high seas and have a very good routine. Then they arrive in Port Said or even Suez… and suddenly all hell breaks loose.
> “There’s a lot going on, a lot of people coming on board, the Suez Canal crew come on board, and at least one pilot comes on board. Those ships are actually piloted by an expert who knows the canal very well… nevertheless, this is a stranger and a new person is part of the bridge team.
> He explained that a convoy could consist of around 10 ships, while a large lake in the middle of the canal - the Great Bitter Lake - allows traffic to flow smoothly in both directions despite the canal itself only being a single lane.
> [...]
> However, he said physics effects such as the Bernoulli effect can result in very sudden changes in a ship’s course, while strong winds may have been another factor.
CNN published a simulator where you get to try to go through the Suez Canal yourself: https://www.cnn.com/interactive/2021/03/cnnix-steership/ This simulator is, of course, ignoring things like communication difficulties caused by language barrier (they speak Arabic), some of the more nitty gritty physics of the task, tides, safety concerns, etc.
There is also a canal navigation simulator in meatspace, if you're up to the task - https://interestingengineering.com/transportation/a-mini-sue...

This has got to be top ten of most wrongest comments on hacker news.

Nah. It’s par for the course when you ask someone who is an expert in one field to comment on something outside of their expertise.
If we consider modern large jet airliners and cargo planes to be equivalent to large ships, most of those planes have advanced automation.

While it’s true that category III autoland exists, almost all of autopilot is done via the big sky theory.
Airplane automation has more in common with drawing a line on a map than with piloting a big ship in a small canal.

because water is more treacherous and a smaller domain of control (as in, it's more complex, greater unknowns, etc) than having cubic kilometers of open air that you can fly through.
Think about it, 2D plane, tough medium that has low visibility, can hide many things. Tides, currents.. EVERYTHING has a potential to be a difficult maneuver / emergency situation.
Just because it was an earlier mode of travel doesn't mean it's simple.

I used to know both the Captain and Chief Engineer of a large ( 600+ foot long ) freighter on the Great Lakes ( https://en.wikipedia.org/wiki/Great_Lakes ). The latter told stories about the former arguing (via radio) with the ship's owners, about speed vs. safety. At least once, after the Captain had backtracked the ship to a safe-ish anchorage in the face of worsening weather, he told the owners "I'll get your ship, crew, and cargo to [destination] long before the Edmund Fitzgerald does" ( https://en.wikipedia.org/wiki/Edmund_Fitzgerald ).
(The actual language was saltier than that. The Captain got away with it, and retired a success.)
