probably hawser a lot shorter than 200 meters, so if engine conks (looks like no power or visible prop wash,  rake-bow barge pushes and trips him.

 

Why'd you pick Sailing Anarchy?  No sails visible.

Because sailboats like to sail between tugs and barges? PSA? Or do we need Tugboat Anarchy? I would start that :-D

All too easy to not realize there's a tow.  And when there is, too often it's a run-down battery-powered red or green on the bow, barely visible.  Joe sixpack sailor (or motorboat) doesn't know the two lights mean a tow, and three white lights mean a really long tow.  And they also don't realize what the yellow lights on tug's stern, means.

If only more of us sailors and motorboaters would take a Power Squadron or Coast Guard Auxiliary course, we'd have fewer sad stories that didn't have to happen.  I took Power Squadrons when i was 14.  No diploma cause you had to be 16. But that knowledge lasts your whole life.  Grateful to the volunteers who teach it.

You can actually find many videos of tugs getting tripped up by their tows all over youtube.

And for more go to pornhub and search ‘Hit from behind’.

Overtaken by the tow and pulled sideways is known as girding.  He's lucky he didn't capsize. 

He's damn lucky, looked like a goner there for a minute or two.

There may have been a following current but the problem was caused by the barges speed thru the water.

It's called "girding".  The tow overtakes the tug and side loads the bollard.  Tugs can and do flip from it. 

Can happen when you have a strong wind or current coming from behind.  Tug makes a turn and the barge keeps going.

Tug is showing 2 white lights, so towing, less than 200m line.  Following current, tried to slow down but barge full of stone kept going?

Do you know sechelt rapids? Roughest salt water rapids on the west coast of north America at the least. 

A Canadian friend has a crazy story about having to cut seine full of herring loose there as they started to get drug in before they could recover the net.

There is a bit more to it than that.  A tug like that is steering with a conventional rudder, meaning it needs speed through the water to control the tug.  Velocity over the ground is speed through the water plus speed over ground.

In a tight river, it may be preferable to slow down to take a sharp corner to reduce the advance through the turn.  But if you slow down too much in relation to the ground, the tug over takes you and girds you.  

It's like hitting the brakes on an 18 wheeler going up a steep icey hill vs hitting the brakes going down a steep icey hill.  More like to jack knife on the way down the icey hill then up, even though the initial speed over the road is the same in both circumstances.

Well put, that's a good description.

A similar problem more SA'ers might be familiar with is when you're towing a string of small boats and the tracks of the towing vessel and tows diverge, resulting in capsize and damage of the towed vessels.

J24s used to be the biggest problem back in the day at St. Pete Yacht Club, Florida. On the turn into the Sailing Center some would turn when they got to the end of the breakwater. But my 17-foot Whaler needed to continue for a while to get the last boat past the corner. Their mass overpowered. 

I used to insist that all towed aim at the rudder of the boat ahead. And NO BOWLINES! Can't be untied under strain in an emergency.

A search for tug girding on youtube led to this interesting and horrifying video by the Transportation Safety Board of Canada:

 

 

Another view of those "Sechelt Rapids", more commonly known as Skookumchuk. Probably the most dangerous tidal flow in the Salish sea.

Personally I wouldn't go through them under any circumstances, let alone towing a big barge.

My classmates would become Docking Pilots after running tugs for five or so years. 

They would tell all new crew to get in their bunk and turn off the lights THEN imagine trying to get out of there upside down with water and fire all around.

Sail safe!
