Could see this going pear-shaped around 1:30 into it; way too much wind , and not enough horsepower. Plus, if you working tugs like that, its generally advisable to pull out BEFORE you flying down the Deathstar Trench and forget to pull up...
Not to mention, y'know, like taking lines on the SEAWARD side of the boat, so nothing sorta gets crushed like a beer can...
Damn lucky, that tug could have capsized or been crushed a lot worse.
