That's a top model you've created there matey!

Probably works better than the real thing and doesn't leak either.
Looks great!

Looking good

Looking under the hull of most virtual ships there's a helluva lot more water sloshing around the empty hull than Lizzie!
I love the UK press - 'new warship leak shock horror!'....I've yet to come across any ship which doesn't suffer a propeller shaft seal leak from time to time. It's not the easiest to seal and maintain a turning steel shaft that exits the hull directly into the ocean.
200 litres and hour? My garden pond pump can handle more than that!!
Best

I agree with you completely.
In most vessels leakage around the stern gland is part of the shaft cooling system.there are not many dry glands.
I believe the Queen Elizabeth has a pneumatic gland shaft seal.

PS As far as the medias knowledge of ships the most annoying thing to me is the use of their expression the HMS Whatever.
HMS stands for her majesty's ship so you cannot say "The her majesty's ship ----

There's a reason it's now known as the Daily Fail!
It used to be a respectable newspaper 25+ years ago and I was a regular reader of it's Sunday edition (The Mail on Sunday) when I still lived in the UK, mostly for the usually informative colour supplement and the comics section.
It has gone drastically down-hill over the years and now resides firmly among the 'gutter press'.

Really nice! Looking forward to it!!
Seawing
Testing the deck air wing and lights
To be honest I was surprised when I opened the video, I expected to see something more like this.
I guess I am just weird .

Very nice, better and better...
Chris, you might be referring to the old wood shaft bearings. They employed staves of a very hard wood called lignum vitae which supported the tail shaft between the propeller and the engine room. Sea water, as a lubricant, was allowed to flow past the gland into a bilge-well in the engine room, from where it was pumped overboard. Lignum vitae bearings were largely replaced by oil-filled white metal stern bearings in the 1970s and 80s. The seal at each end of the tail shaft was effected by sets of O-rings, with a small oil header tank in the engine room which maintained the oil pressure and so prevented the ingress of seawater. I was an engineer on a ship that had this conversion work done in dry-dock in Cardiff in 1976, and it was interesting to be involved in it.
Just lately, I see that a return to seawater lubricated bearings is contemplated, though it is unclear to me whether lignum vitae would once again be utilised. I'd like to see details of HMS Queen Elizabeth's arrangements.
And you're right...it's HMS, not the HMS :O)
Paul here is the type of gland I have been referring to.

I was the manager of a well known yacht manufacturer and indeed have had many yachts and boats myself.Well being called Drake and born in Plymouth you would expect it.
Hope the link helps explain to all who are interested in stern glands.
Cheers Chris
PS The stern glands in the Queen Elizabeth are pneumatic.That is like an innertube made of very tough material and tightened onto the shaft by being pumped up with air
Thanks for the link Chris. I remember stuffing boxes on valves and shafts but not on stern tubes of that vintage. Maybe it was the diameter of the shafts of large ships, and the consequent impracticality of stuffing boxes... I don't know - its been 30 years. The packing was manufactured by a company called Beldams, covering everything from ice-cold seawater to superheated steam !
Plymouth, eh ? I was at the School of Maritime Studies on Portland Square for two years. The buildings are all still there, including the Planetarium. After that I was up on Tyneside for another year.
And of course, you make the very valid point - how can any rational human being NOT be interested in stern glands ?? ;O)
