There is no doubt Mark has uncovered documents that a three bladed centre propeller was said on paper to be made.
However what is said on paper doesn't always follow in practice.
The only real true if the paper work is correct is still lies buried at the bottom of the Atlantic seabed.
Wrong.The only real true if the paper work is correct is still lies buried at the bottom of the Atlantic seabed. To remove the seabed debris from the propeller is a very costly and expensive operation indeed.
Well, find some proof then. Just remember, an opinion is not a fact.Sorry to tell you what may be seen on the barge and is a three bladed centre propeller does not 100% guarantee that was install on the ship. Documentation yes. 100% for sure still lies buried at the bottom of the Atlantic ocean.
Not a member of any clubs myself (I'm a lone wolf) but these three major ones may interest you:With regards the Titanic societies is there a specific way for one to join? I dont want to go onto Google and sign up, for want of a better one, a duff one!
Seumas, I recognise you do add useful information to ET. At some times you can be quite out spoken. But hay we are not all the same.Well, find some proof then. Just remember, an opinion is not a fact.
Mark has actually found proof of a three blader in the form of an original H&W document.
Your proof on the other hand consists of "How many times I order something on line only to find some thing else arrives." You would be laughed at and humiliated if you made such an argument at a Titanic society meeting.
Drop the argument, it is annoying other posters.
This is how the effectiveness of the four-blade and three-blade propellers was tested. You make two identical ships and give one a propeller with three blades and the other with four. Then you look at which one has less vibration and sails faster.That the question I ask why did Olympic have a four bladed centre propeller in the first place? As the trend was to have three bladed propellers. And I can only think that came about from the new technology of turbines.
Where Lusitania & Mauretania started life with three bladed propellers and change over to four bladed propellers with improved performance. With about fours years of service of the two ships, it seems logic to fit a four bladed propeller on Olympic turbine. So what made them think of a three bladed propeller would be better? Then fit a four bladed propeller on Britannic. Followed by a three bladed on Olympic1913 and then back to square one with a four bladed propeller again!
Just a matter of interest do we know if it was the same original propeller as fitted in 1911?
As Mark has the paper work to show that a three centre bladed propeller was made for Titanic,
where we have to stick with that until prove different.
As with Titanic and Britannic was given on a piece paper of there sinking position, which years later on proved not to be the case!
