I was perusing the Ship nostalga site when I camr across these pics, people are always asking what it is like in a wheelhouse for detail and I thought the dry dock pic was good for showing the uderwater detail, such as the screws, talking of screws Husky has clipped something, working with subs a working hazard.

Nice pics. For me specialy the one in dry dock :-))
-
Wow, do these ships still use the telegraphs for engine control?
-
That takes me back. Always used to see Setter years ago
-
I forgot to mention the top pic is Husky's bridge and the middle one is Sheepdog. When I was in Chatham, on the Mastiff the telegraphs were both covered in green baize cloth and the handles were coated in plastic red for port and green for stbd. The Mastiff had one AB polishing all week, which included all the brass screwheads in the interior panelling. It was not uncommon for RN officers to come aboard her after their vessels berthed to inspect her bright work as by then the RN was painting over brass work.
-
Yes they were still Blocktube manual control from the telegraph.

Hi ZZ56, yes the dogs were all bridge control through the telegraphs, if the system failed they could be changed over to work as old fashion engine room control type telegraphs. Part of the vessels planned maintenance was to check that the emergency engine room control system worked.
-
Hi Bob, if I had known you was going to answer , I would have kept quite, being an engineer you can technically explain it better than me.
-
Some of the Wightlink Ferries are Voith Schneider propulsion and still using Blocktube controlls.

It's a perfectly good system, I was just interested to see it still in use, especially on a government vessel.
I saw some photos of a 1946-built tug in Quebec and the pilothouse had been reduced to a chair off to one side with a joystick and computerized map.

Thanks Dodes
The hull pic gives me an opportunity to ask a question I have been pondering about.
On the Kalakala I noticed some rings near the rudder and wondered what they were for?
The hull you show also has rings near the rudder. I have just been reading Grey Seas Under too
so now maybe I'll hazard a guess - is it some way of assisting steering (probably not :D).

The last photo gives away the answer - they're for attaching pulley blocks and chain hoists to when it comes time to pull out the propeller shaft or rudders for maintenance.

Thanks - what a really simple answer - I just thought the guys were taking advantage of them being there.
I might have a few other questions too hmmm?

Hi ZZ56,
Yes you guessed right, about the ring pads.
-
The bridge photos take me back. Same Bloctube (no 'k') telegraphs and wheel as Meeching, a lot of the same running gear as well, including the Lister twin Blackstone diesels.

Funny you say that , but that is where the Dog class originated from I believe, at the time I suspect it was one government department using another departments design, but they where a very successful design unusual for the MoD.
