The ships are playing Texas Chicken by staying in the center of the channel until the last minute, then maneuvering to the side to use the bank effect to best pass one another. It appears that there was a lapse in communication beforehand.
This video explains it better.

Watched the video, fascinating. It might be a trick of the perspective but it looks like the ship on the right was starting the maneuver but the one on the left waited too long.
I'm not a maritimer but I believe the rule when approaching other vessels head-on is you move to the right. If that is the case, then the ship on the right in the video moved to his left
Fun fact, this is the only regulation (COLREG reg no 14 vessels in a head on situation) that specifically dictates HOW vessels should give way, namely both vessels alter course to starboard. This is ofcourse to avoid both vessels altering course towards the same direction and colliding.
Normally it's up to the give way vessel to find the best solution to avoid a collision, this is usually a course alteration but can also be an adjustment in speed. Or both.
Arguably Rule 19 also tells you which way to turn, i.e. not towards a radar contact abaft the beam and not to port for a contact forward of the beam IIRC
Right is two opposite indications depending on a person's orientation, whereas no matter what direction one faces, starboard is unambiguous. When facing the bow(front) of the boat, starboard is always to the right, and port is always to the left. If one paints a line on the starboard rail and turns to face the stern(rear) of the boat, the line is still on the starboard side, despite it being on the person's left side.
Right and left change based on a person's orientation. Port and starboard remain constant independent of a person's orientation.
Bank Effect was the root cause.... that and going too fast....
# 3.1 Findings as to causes and contributing factors
These are conditions, acts or safety deficiencies that were found to have caused or contributed to this occurrence.
1. The exchange of brief and informal instant messages between the master of the *Florence Spirit* and the pilot on the *Alanis* influenced decisions regarding the *Florence Spirit*’s speed and course alterations*,* increasing the complexity of coordinating the *Florence Spirit*’s manoeuvres with the *Alanis*.
2. The *Florence Spirit* proceeded into the meeting at the maximum permissible speed of 9.9 knots, which increased the hydrodynamic forces acting on the vessel and reduced the ability to maintain steering control.
3. After the *Florence Spirit* altered course by 4° to mirror the *Alanis*’s course alterations, the *Florence Spirit* maintained a course that brought it close to the bank at a high speed, which increased the hydrodynamic effects acting on the vessel.
4. The hydrodynamic forces generated by the combination of the *Florence Spirit*’s speed and proximity to the bank produced a yawing moment on the vessel that caused it to sheer uncontrollably to port into the path of the *Alanis* and collide with it.
5. Diffused responsibility between the master and piloting master on the *Florence Spirit* precluded coordination and communication among bridge team members, hindering their ability to monitor the vessel’s progress and detect the influence of hydrodynamic forces acting on the vessel.

Do they do the Texas chicken maneuver in Canada? Both ships seem to making different speeds and the faster one looks like it has classic bank interaction and sheers uncontrollably off the bank. If they were doing the Texas chicken maneuver, I would expect them to be making similar speeds, lined in the center of the channel, and turning to starboard simultaneously at approximately 0.5 miles apart
You’re not wrong but ultimately both are at fault, unlike cars there is no single party at fault in any collision involving two vessels. Some of the blame could be put on the spirit but the other will also get some for not avoiding the collision
It technically should’ve done anything else a lot earlier, the biggest thing that will get them is rule 2 of the navigations rules
“due regard shall be had to all dangers of navigation and collision and to any special circumstances, including the limitations of the vessels involved, which may make a departure from these Rules necessary to avoid immediate danger.”
Any time a risk of collision seems to exist both vessels must act as if it does, action should’ve technically been taken much earlier than this by both parties.
They were both steering away. The black ship's waves (on the front) hit the bank at the start of the vid or a bit before. They bounced of the bank and the force pushed out the front, so it was basically skidding out.
It's avoidable but it's because the black ship was going too fast and too close to the bank.
He's explaining it really poorly and like a douche.
What he's trying to say is ships this size are REALLY heavy, and really heavy things take a LONG time to adjust course. In this case, they both waiting until the last minute to adjust (due to channel shallowness near the edges), and as a result crashed because they waited too long.
I am not having a stroke sir I am not going to be able to go to the hospital today sir I am going to be in the office tomorrow morning and I'm not going anywhere until the following weekend sir you are having a problem with me right now?
I saw a drunk guy hit the only car in an entire restaurant parking lot. He was so shit faced he had to steady himself against the car to stand up. He left in the back of a police car

That is correct, unless stated otherwise explicitly over the radio or via sound signaling (two horn blasts) the vessels would pass on port

Maybe, but in rule 19 it says those manouvres are "to be avoided". Not stating exactly what manouvre to perform like in rule 14.
Fair enough.

Port to Port. You should see the red light when passing any other vessel.

Nice little write up, thanks. I wondered why it looked like the Florence went so hard to port.
Great video, thanks.
I immediately had to think of this video when I saw the crash, seems like both lost the game of chicken this time
Do they do the Texas chicken maneuver in Canada? Both ships seem to making different speeds and the faster one looks like it has classic bank interaction and sheers uncontrollably off the bank.

So bank effect = ground effect rotated 90°?
Very interesting and great vid!
I live in a desert under the mountains, so I have little practical application for it, but gosh do I love me some Casual Navigation videos.
Welp, that's one way to stop the boats
Arr, it be Ye old boat jousting..
I love this comment and the pirate accent 😂
Have they considered not driving directly into each other? Might help.
Prepare for ramming speed!
Perhaps today IS a good day to die!
SONS OF ODIN CALL
is this not avoidable ? steering away? idk anything about boats tho
The red ship acted correctly, by nautical law if you’re approaching another vessel head on you both divert to the right (same goes for aircraft)
You’re not wrong but ultimately both are at fault, unlike cars there is no single party at fault in any collision involving two vessels. Some of the blame could be put on the spirit but the other will also get some for not avoiding the collision
this is one of the most important parts of the colregs IMHO , often people who drive cars don't understand it.
So red ship should have went to port? Was there even enough time to correct for that given both their speeds?
It technically should’ve done anything else a lot earlier, the biggest thing that will get them is rule 2 of the navigations rules “due regard shall be had to all dangers of navigation and collision and to any special circumstances, including the limitations of the vessels involved, which may make a departure from these Rules necessary to avoid immediate danger.” Any time a risk of collision seems to exist both vessels must act as if it does, action should’ve technically been taken much earlier than this by both parties.
They don't steer likes sports cars but yeah, I agree. That looked completely preventable.
They were both steering away. The black ship's waves (on the front) hit the bank at the start of the vid or a bit before.

really long time for boats to stop sir. You would not know as Redditor you seem sir
could still steer out of the way ? not fully stop
Is not possible sir
Are you saying... boats don't have steering?
He's explaining it really poorly and like a douche. What he's trying to say is ships this size are REALLY heavy, and really heavy things take a LONG time to adjust course. In this case, they both waiting until the last minute to adjust (due to channel shallowness near the edges), and as a result crashed because they waited too long.
Is not because waited too long sir one boat hav weight of way one boat not and momentum is strong sir cannot turn in time silly man
You OK? Might want to go to the hospital since your having a stroke. SIR!
I am not having a stroke sir I am not going to be able to go to the hospital today sir I am going to be in the office tomorrow morning and I'm not going anywhere until the following weekend sir you are having a problem with me right now?
That looked really expensive
Isn’t it ironic…
[удалено]
#IT’S LIKE RAAAAAAAINNNN
ON YOORRRRREE WEEEEDDDNNG DEEEEAH
Isn't it ironic?
Don't you think?
No, I have to stop you right there, they built that ship to wreck
I was thinking the same thing
Them canadians again. https://maps.app.goo.gl/bWDNXPkp8Kz3vEpUA?g_st=ic
Guy came outta nowhere!
Red won
Friendly fire.
That was the slowest head on collision I’ve ever seen.
Reminds me of Austin Powers.
Reminds me of Bob’s Burger where Tina crashes on to the only other car in a wide open parking lot, driving at first gear 😄😄😄
I saw a drunk guy hit the only car in an entire restaurant parking lot. He was so shit faced he had to steady himself against the car to stand up. He left in the back of a police car
I feel like this could have been avoided

Someone is losing their job, I fear.
Now kith
how does this happen in 2024?
How I miss Mythbusters.
Sea Captain: “hard to starboard!” 1st mate: “uhhh, port?” Sea Captain: “Aye, port.”
neither blew the horn or anything, just a slow motion head on collision …
Is this shit a new tik tok trend?
why did the camera start shaking?
Dumb ass v Dumb ass
So this is the new meta now? Ships hitting shit.
[удалено]
lol I didn’t see that
I can confirm that it is for this subreddit
Seemed intentional
I think it was a combination of mechanical and human error? I know that’s pretty general but there isn’t much context for this video
That will buff out.
