triple screws {What did that red sign mean?}

greenspun.com : LUSENET : TitanicShack : One Thread

In the movie, there was a sign on the rail of the stern that said: "NOTICE. This vessle has triple screws. Stay clear of the blade." What exactly did this mean?

I believe that it was relating to Titanic's three propellors. I don't know how you were supposed to stay clear of them if you were up on deck though. Hope that helps! :-)

That sign was intended for approaching vessels, small or otherwise. The screws certainly could raise the devil with anything near them when they were operating. They managed to rip the liner New York from her moorings almost causing a severe collision. Lots of turbulent water happening in that area! I believe a sign with a similar message is still posted on commercial ships today as the physics of the that occurance certainly has not changed.

As if any further proof were needed, beyond what Peter says, remember what happened when the Britannic went down. Several lifeboats were launched before authorization by the bridge, while the ship was still under way (the captain had thoughts of trying to beach her). As the propellers came out of the water, still turning, they pulled two of the lifeboats into them, which caused most of the thirty or so deaths of the Britannic's sinking.

Lesson: don't get too close to big ships; they are POWERFUL.

A similar incident occurred at the conclusion of Titanic sistership Olympic's maiden arrival in New York in 1911; she pulled a tugboat into one of her screws. Nobody was hurt but the tugboat sustained some serious damage.

Also note that if you were up on deck you could NOT read the signs because they all faced away from the deck and were mounted on the outside of the rail.

Hi Tom: I remember, in my Navy days on an Attack Transport, we were going into our home port of Little Creek, VA at a less than fair tide and to reduce the draft of the ship, we had to offload several LCVP landing craft while still underway (albeit at a slow bell) in Chesapeake Bay. As we were being lowered, in a Welin davit BTW, I looked toward the stern of the ship, and saw the ship's propellar, which always had one blade out of the water, turning and whacking the water. That is a sight and sound I won't soon forget and can visualize 30 years later. I can imagine the horror of what happened to the boats and people in the water during the sinking of Britannic!
