You can tell this ship uses direct drive diesel propulsion, by the way the propeller springs back (even back and forth) a bit after it stops, due to compression in the cylinders.
Oh my Goodness, these things are really freaky. Just imagine diving and suddenly seeing or hearing one of these props close to you... That is really scary!
Well In britannic disaster that unfortunately happened, a German U-boat stroke a torpedo at Britannic and when it slowly sank, the propellers came up onto the water and caused a stream which leaded the life boats there and so... 1,600 people survived and all 30 who died where crushed by the propellers... There is a movie of Britannic and the scene of that propeller thing...
Imagine how it was when the Titanic's sister ship the Britannic was sinking. The Britannic struck a mine during WW1 and started sinking fast. She was almost identical to Titanic and was being used a hospital ship. The captain restarted the engines to try to ground the ship before it sank. Her propellers where as big as Titanic's, 23 feet six inches or 7.163 meters across. They were launching the lifeboats while the ship was going down. The propellers came out of the water just like you see here. The huge propellers sucked two lifeboats into them and chopped the boats and everyone into pieces. The captain stopped the engines right before the third lifeboat was pulled in.
I remember seeing one when I was a child and haven't seen on half way out of the water like that in years, one thing I noticed when they engage the propeller how quickly the boat move forward or backwards cool video thank you so much for sharing
@2fast4u510 yes but the balast tank is not filled with water so when it is full the boat go's down in the water and it isent called just a thing its called a prop (propela)
Agree absolutely; I'm not sure it is just the propeller though, I think I fear the whole thing for some less rational reason. Glad I'm not the only one though! :-)
What kind of lines were used? When I was in the navy we used to use dyneema lines to get the last kts off when mooring, on an LPD, Insanely strong lines
Right with you there. Ships and ports fascinate me, but I have a morbid fear of falling in the water alongside something like that and getting mashed, or squashed between ship and quay. Just looking at it makes me feel queasy (what kind of man am I you ask...)
@12GAshotgunnersrain You and me both. I have been afraid of boat props since I was a kid and my uncle kept his boat in the garage with the engine facing the dryer. I was always terrified it would suddenly come on. LOL
I don't know about this but im from around the great lakes and they take on ballast(water to keep the prop in water lol) before even giving engine orders.
They move a lot of water I mean really almost twice water when they are spinning backwards... I always wonder if it is a flaw on the propellers design, I mean every single big ship has it, that propellers look concave in the wrong direction, I don't know why or find a reason for that and this video proves that, backwards spinning moves way a lot of water more than regular forward direction
Hi, Im a film student working on a short documentary on ship passing through the channel, I saw your video on the ship propeller and I was wondering if I could use it in my film? Its non commercial film used for school. Let me know! I would of course credit your work.
