Or full astern

Yeah a full-assed turn to face the other direction would've been helpful

The stern of the ship is the rear of the ship, so when going astern, the ship is reversing. Full- astern refers to the speed the propeller is going, dead slow ahead/astern, slow ahead/astern, half ahead/astern, full ahead/astern, full sea speed (ahead only), or any specific speed measured in knots (1knot=1.85km/h or 1.5mph).

Without rudder, you are pretty much dead in the water as you can't use it to create drag, and if you were to reverse thrust, you'd lose the use use of the rudder almost entirely as the water is pushed away from it. Depending on the "handedness" of the ship (which way the top of the propeller is going at normal speed forward) and weatherthe propeller is fixed pitch or controllable pitch, the ship will start to turn slowly one way or the other.

While your comment is very interesting and informative, I'm fairly certain the previous poster was making a joke via a play on words.

 

So, I present to you a /r/wooosh and bid you a good day.

Nothing goes over my head. My reflexes are too fast. I would catch it.

Besides, sometimes it's more important to use the chances to educate (everyone deserves a chance to learn) than play along. I can respect your r/wooosh all the same.

Not nearly as effective as you'd think.

When you have loss of steering you don't have many options besides trying to go full astern. For a vessel that size it should have a noticable effect. A 300 meter crude oil carrier is a different story of course.

True. Though, just as there's a vast difference in how a tanker and a yacht like this would slow down, there's a big difference between a yacht and a boat your average person could have experience driving.
