Looking at that picture made me start thinking about the Ever Forward grounding in Baltimore . It's known that ships can get "squat" or "ground effect", causing suction on the bottom. Just wondering if the can get "side squat" as well. The ship was doing 13knots in a fairly shallow and narrow channel. Could side suction have pulled the boat to port ? Depends I suppose on how the channels are dredged .
Not that I have ever had to do it but I have heard that when- f'rinstance - you approach a turn to - lets say - starboard in a skinny canal you put the helm to port.
Thats what I was told back in the dreamtime.
Quite a bit 'out there' about it

Bank effect, as it is sometimes know, is a factor in narrow channels. I think it is the Bernoulli principle that means that as water gets squeezed between a vessel and the bank, it is forced to go faster, hence lowering the pressure differential between sides of the ship, which will cause the stern to pull towards the bank and the bow to move out.
This was a likely cause of Ever Given parking across the Suez Canal, but I don't think it likely to have been an issue for Ever Forward, although I stand to be proved wrong by the investigation or any of the experienced ships' masters here.

Wasn't that partly blamed for the Evergreen incident last year?

Certainly if you cruise on canals you will know that there is a tendency for a boat to get sucked into the bank - especially in a lock - or two boats to get drawn together when one is passing the other.

From Splash -

In a letter sent earlier this month to Benjamin Tsai, president of Evergreen Shipping Agency (America) Corporation, Maryland comptroller Peter Franchot asked the company to set up a $100m fund to cover the environment-related costs, as well as economic costs, in particular for the seafood industry.

The move by local politicians was quickly attacked by many Splash readers including this site’s lead columnist, Andrew Craig-Bennett, who labelled the action “shameless”, commenting: “I hope Evergreen and their P&I Club treat this attempt at blackmail with the contempt it deserves.”

It will be interesting to see how this pans out.
The Maryland folk also admit that while they are concerned about damage to oyster beds et al, there is such a labour shortage in the Chesapeake that they have not got any willing punters to harvest the oysters that have not been given a headache by temporarily 'Ever Grounded'.

It seems the grounding of the Ever Forward was pilot error according to the report into the incident. The pilot has not commanded a vessel since and has now lost his licence.

How Ever Forward got stuck in the mud >> Scuttlebutt Sailing News (sailingscuttlebutt.com)
Yes, well found Roger. I did actually know this as my friends in the US Coastguard and US Pilots association had already told me in September that it was the fault of the pilot who was fiddling with his mobile phone. One of the guys said he knew the pilot personally, and could actually see the stranded ship from his house.

The guys are over here for regular boondoggles at IALA (which bizarrely has it’s headquarters in Saint Germain en Laye).

My apologies for not sharing this intel at the time.

The report states that the pilot was in command. A first officer I know claims that the only sea where the pilot is in command is in the Panama Canal. Everywere else it is the captain

He’s basically right, but he’s simplifying the position in US waters:

This is from a handbook published by the American Pilots Association:

“As reflected in an official statement adopted by the Trustees of the American Pilots' Association in 1997: Navigation of a ship in United States pilotage waters is a shared responsibility between the pilot and the master/bridge crew. The compulsory state pilot directs the navigation of the ship, subject to the master's overall command of the ship and the ultimate responsibility for its safety. The master has the right, and in fact the duty, to intervene or to displace the pilot in circumstances where the pilot is manifestly incompetent or incapacitated or the vessel is in immediate danger (in extremis) due to the pilot's actions. With that limited exception, international law requires the master and/or the officer in charge of the watch to "cooperate closely with the pilot and maintain an accurate check on the ship's position and movement.””

“State-licensed pilots are expected to act in the public interest and to maintain a professional judgment that is independent of any desires that do not comport with the needs of maritime safety. In addition, licensing and regulatory authorities, state and federal, require compulsory pilots to take all reasonable actions to prevent ships under their navigational control from engaging in unsafe operations. Because of these duties, a compulsory state pilot is not a member of the bridge "team." Nevertheless, a pilot is expected to develop and maintain a cooperative, mutually supportive working relationship with the master and the bridge crew in recognition of the respective responsibility of each for safe navigation.”

This takes me back…

Back in the dreamtime, before the ISM Code, I took a look at CNCo’s Fleet Instructions and summarised them as:

“Thou Shalt Not Carry Un-Manifested Cargo”
“Thou Shalt not Appear in a Passenger Space Out of Uniform”
“Masts are to be painted Mast Colour” (“mast colour” was not actually specified, but see below…)
“Safety at sea is a good idea”.

Having persuaded my Managing Director that Something Must Be Done, an act that bought me thirty five years of undying enmity from the chap who had written the last edition, I got the immediate past Commodore and Commodore Chief to write something sensible, which I edited and added sections on interaction on the lines of the above, because nobody else was going to, (not controversial, because necessarily tentative) and safe speed (highly controversial, but the past Commodore and I could both quote the “Lady Gwendolen” case from memory, and we won the argument).

This volume was named the “Fleet Operations Guide”, and was instantly rechristened, by the then current Commodore, a Scotsman of few but carefully chosen words, “The Fog”!

What I had failed to foresee was that our text, which had taken months of work, would be instantly pirated by other shipowners in Hong Kong! The sincerest form of flattery!

Within the FOG I thought you were going to say the mast colour should be a yellow, like in traditional sailing ships.

However the best bit is how your FOG was adopted by so many other shipping companies, well done.

That’s indeed what is normally taken to be “Mast Colour”, and the two ancient recipes for painting ship - one from Victoria’s Navy - that I have been able to turn up also agree.

However, Alfred Holt & Company’s Blue Funnel Line, aka the Welsh Navy, with whom Butterfield and Swire’s China Navigation Company were closely associated, favoured a mid brown, so that gets us halfway there:

I wonder if that has something to do with the marina, where visiting boats seem to like to give my boat a little "tap" when they come to the visitors berth.
They get sucked into one's berth instead & it is actually one's own fault, for being there in the first place. Not theirs.
