At absolutely no point in the video below, fittingly accompanied by Yakety Sax, does it appear that this excavator is going to successfully board that boat. It looks like a bad idea, goes wrong almost immediately and quickly transforms into a frantic scramble to get the excavator off of the boat.
With the boat lost, the excavator operator then tries to at least save his machine, with one last desperate grab for the shore, but ultimately fails. And to add insult to injury, as the machine tips back into the water, a bucket full of soil falls on his head. Good grief.
