Professional Mariner did a piece on the Jake Shearer when she was a newbuild and went into some detail on their choice of the Taisei Articouple system. Here’s the full article: http://www.professionalmariner.com/American-Tugboat-Review-2015/First-ATB-for-Harley-Marine/
When I first read the article, this paragraph struck me as odd:
There is also a hawser kept along one side of the barge. If the sea state becomes so severe that the tug cannot comfortably stay in the notch, the hawser is set up so the tug can quickly move out of the notch and switch to the towing mode. Basile said that executing such a maneuver would be very rare and might never happen within the lifespan of the ATB, but the hawser is in place just in case.
It just seems like a fantasy that in seas so bad the tug is unable to hold the notch that the crew would be able to execute a safe breakaway while also rigging up a hawser, and then get the barge under control and following.
