VIIC/41 - Schematices drawing

[Pat]

Dougie, I'm trying to get one of the pictures of the anodes scanned in and as soon as I can, I'll try and either post them here or get them to you another way.

I showed the picture to another sailor here who's going to scan it for me and was asked immediately if those were anodes, so I'm sure that's what they must be.

only in Gatos

That may be the best I will get Its one of them things that was never photograph. Where would I start looking for pictures of the high pressure air bottles for the Gatos?

Hi Maciek

Can you remember where you saw the photos? Its likely that they are the same or very similar

I took this shot of the USS Silversides (Gato).

[NZSnowman]

Thanks Wildspear!! Very useful it show me the shape of the bottles and a Pressure hull opening (just right of the bottles on the left). Thanks

Here my best guess so far of the bottles of group 2. Top view & Side view.

Hello Simon

I read your question once again and realized I misunderstood it - "under deck" as internal.

Here is the photo of machine room section of the type XXI boat.
Visible in background flask is (I suppose) Diesel engine starting flask.

Does the vent located above the line of vents, just forward of the exhaust outlet, have a reason?

[NZSnowman]

Many thanks to eveyone for the information on the bridge. I am going to work on this over the weekend 

How did the voice pipe work I can not imagine the voice pipe went through the pressure hull.

Good question on the voice pipe, what a terrible hull penetration! Even if you relied on outside pressure keeping a cap shut, scary [insert 3 stooges "nnnnnaaaaaaah" scary noise here]

Hi Wink

It looks like they did penetration the hull but they did put in 3 valves in the voice pipe between the bridge to Control Room

Hello Simon,

I am not certain, but I believe that one vent forward of the exhaust outlet and above the row of vents may be for a foot / hand hold intended for boarding the boat at this location.  Some photos and drawing that include the harbour railings show two closely spaced stanchions on the deck at this point in the hull.  Also, somewhere I remember this being mentioned as a boarding station - sorry can't recall the reference.  The David Westwood book has a good diagram showing this on page 26/27.  I hope this helps you!

Cheers,

Bill

Hi gents,

I'd say your theory about a foot/hand hold is very plausible, Bill. Do you think this is correct, Simon?

Cheers,

Dougie

NZ - thanks for that, interesting!

Simon/Bill,
also interesting! Gatos had a "sea ladder" - cutouts, sometimes in a zig-zag pattern. I'm pretty sure they had a "foot plate" or stair tread welded inside to place your foot, and would have had to be reinforced with angle brackets because that hull casing - in Gatos anyway - was tissue thin and wouldn't take weight. Yes, 2nd pic, shows a TINY "L" lip welded inside
