He'd be dead if he was in the water O_O

Strewth. I never realised they were run so fast. I'd have expected much more cavitation at that RPM. Good screw design eh?

When did sea mariners start calling a ships SCREW a propeller(prop). I always thought a prop was on a aircraft.

The spiral is a totally vacuum...am i right?

were u inside a room beside the propeller or in the water on first scene

Wow.

I've read about cavitation but never actually seen it happening. Pretty cool idea to put a view window there.

cavitation is bad for the propeller-it causes damage to the blade (wikipedia has a good explaination)

Is is bad to have thoes cool looking ripples (cavitation) and all thoes bubbles at the back of the ship?

No one is swimming in that water. You are looking through a port hole cut into the bottom of the ship directly over the prop to inspect it. The prop is roughly 30' tall, easily one of the larger props props out there. There are bigger, but not by much. The hole is cut into the ship to inspect it for cavitation issues. Which, by the looks of the video, seem to be a serious problem....
