Boat sinks after hitting tug rope

The news item is brief, and I'm not sure of the boat brand and size. But it seems likely it was a twin engined boat on the plane. I don't see how else the props and struts would be ripped off after hitting a rope. Maybe there will be more detailed reports once the guys get off the P&O cruise ship in Brisbane tomorrow.

Seems to make a case for a single engined boat with skeg-protected prop!

Not trying to scoot between a tug and it's tow would also be a good idea

Sure, but we don't know yet whether there was a tug and tow present!

I suspect that there wasn't, or else the tug would have rescued the guys.

looking for some enlightenment here from the old salts as i'm a stickler for grammatical accuracy. Do tugs tow using a "rope" (a tow rope) or is the link between tug and barge technically called something else? I actually don't know....

On a tug the steel cable used for towing is called a "string or line".
Wire ropes is the proper terminology for the tug line.

I have never heard of a tug rope. I have heard of a tow line. Tow lines are made of wire rope which doesn’t float. Is “tug rope” Aussie speak for something else?

Chains typically connect tugs and barges here.

The term 'tug rope' in this case is a quote from the news report. Journalism being what it is these days, who knows what it was they hit, whether or not there was a tug in the vicinity at the time, etc. Another report I saw said there was a 'thick rope floating in the water'.

I would be curious to know if they were anywhere near longline fishing activity. Those guys have floats on their line, but I don't know whether there is wire in it. To tear off running gear and leave a hole in a boat would take both a fair amount of boat speed and a substantial line of some kind. I hope there is a follow-up report.

My personal experience with the media is that they get it half right and only half the story.

I looked at available reports, which are sketchy. There is mention of a rope, no mention of a tug,a barge, or anything like that. The crew have been taken to Brisbane,there will likely be interviews to come. My impression, and it`s no more than that, is that they simply came into contact with a large heavy line.

Tow wire. Chain bridle connects barge to wire.

could have been a trailing line for emergency pickup. They crossed too close behind.

And or cat with protected prop and rudder.
I have taken single engine and a couple of cats across to New Cal and Vanuatu, exposed anything would freak me out and the water there is clean compared to many places.

The video included some pictures, once of which showed a sport fisher style boat in the background. So likely twin-engine with props on shafts, not outboards or stern drives. Thus the 'skeg bearings' mention in the article are likely what we'd call shaft struts here in the States.

More details would be of interest, but what was written doesn't seem terribly incorrect, at least not compared to some news articles.

“Tug rope” could be anything!
I frequently find floating rope debris and nets all matted up, sometimes into quite a large mat that floats just below the surface.
Some of the ropes they use to pull these nets are easily 3” diameter.
I can see where running over such at speed could do significant damage.
The open ocean barge tows around here use very long cable with a “catenary”
( usually a length of VERY heavy chain) in the middle to keep the line deep and to allow the water to act as a shock absorber as the towline moves up and down in the water. The rougher the water, the longer the towline. Cable cannot be allowed to snap up tight, it will wreck the tow boat.
Running over a towline like that will defiantly sink most small boats, and probably large ones too.
The best prevention is sharp eyes at all times, and following the rules of the road.
A tug with a tow is plainly marked as such, as well as is the tow, even though they’re often barely within sight of each other.
All accidents are not preventable, but many can be. The insurance industry banks on this fact.

If a tug was towing the rope when they hit it, the tug would have been on scene of the sinking already. I'm sure the tug operator on watch would have seen the SF hit it. So me thinks its was just a piece of free floating heavy line.
If it was an actual tow cable connected to a barge, they would have been run over by the barge.

what, you mean that a barge has a floating line behind the barge or other tow that could be caught in the propellers by a boat going behind too close. who would have thunk it.
You mean they drag a line in case the main line breaks so they can hook up a new line in rough weather without having to come alongside?

If I see a tugboat I automatically assume there's a barge or something else somewhere nearby, and prepare to alter my course to not be anywhere near the tug's path.

Really? Where is that a common practice?
