Tom,
Thanks, it is more fun moving them around, not having to untie or mess with them, and still have solid link control.
Here is a new video making up a three long and pushing it back up river.
Video of the twin screw tow making up a three by one (or is it a one by three?)
The mag latch system works even BETTER with loaded barges, and I have always like moving heavy loaded barges compared to empties. Empties are MUCH harder to make them look scale, while heavy loads are easy since momentum is a big advantage. Also the sail area /windage is much less on loaded barges.
