Academy 1/400 titanic refurbishment

[peterairfix]

I have been on the go since November last year and have finally finished her it's all the refurbishment consists of is changing the plastic kit railings with the photo etched ones and it makes one hell of an improvement.
But in between some how I have lost the centre prop
The original below for comparison

Great build.
Question. Why did Titanic have so many cranes on the stern? I spot 6! Why would she want so many in such a small area. Anyone any idea or know!!!
