Hello TDW, the first schnorkels were installed on training vessels U-57 an U-58 (IIC). In September 1943, U-236, a type VIIC, was the first combat U-Boat to receive the schnorkel. A new type of schnorkel was installed on U-235 and U-237 (VIIC) in a well in the deck casing fore of the conning tower.

In 1944/45 was schnorkel equiped with "Bali", "Naxos" and "Athos".

With Schnorkel was equiped only (of in SH5 game U-Boats) the typ VIIC and VIIC/41.

Thanks for the info. Now my question is should I make the snorkel available to all uboats or only the ones mentioned above?

Nice find Josef. I have been searching for an hour about uboat dates and snorkels and I couldn't find anything!!

I say all!

May be is better to keep historical specifications of the U-Boats

Only for VIIC and VIIC/41. Just my opinion.

I have an easier solution to this that will satisfy everyone: the snorkel is enabled via an entry in the .sns file. Thus is someone wants to use it on another sub and/or wants to use it earlier they just edit the .sns file :up:

For VIIC-type:
Max speed with e-motor and snorkeling = 6 kn (vibration problem of the snorkel)
Max speed with diesel-motor and snorkeling = 9 - 10.5 kn (vibration problems)
First appearance of the snorkel: Sept 1943 and without any radar-addon
Depth of u-boot when snorkeling: ca. 16m
No hydrophone-ability when snorkeling and motors are on.

Where is this highlighted yellow information?
The rest looks accurate compared to my research.
All i read last night was, max 6 kts submerged to prevent snapping off the tube.

We can run our boats about 9kts submerged with periscope clear as day in SH5, which is not realistic from what I read, (vibration interference) so I dont see any reason to go for complete realism on this, unless some hardcore history buff modder comes along and wants to try to make it realistic.

Here I'm at 13m depth at ahead full on diesels. Got the snorkel spray and wakes added:

now for the engine exhaust from it....

On this video it is positioned right before the tower closer to the left side, and fixed to the tower when rised/installed before submerging. So there possibly were different variants of where to install it, depending upon base facilities, workers skill and u-boat captains wishes I guess.

How about the idea of removing one of the periscopes (obs. scope for example) and to replace it with telescopic snorkel (if hinged is not possible to merge in game) when this upgrade option is chosen? And then to use the same interface buttons as for obs.scope interface buttons to rise/hide it?

That should be more realistic I think.

When I was searching for the years the snorkel came out, I seen it said max under water speed was 9 knots due to pressure on the snorkel.

Added the exhaust to the snorkel:

I will limit the speed of the uboat when snorkel is raised. This can only be accomplished with those using my UIs mod. I will also limit the speed when a periscope is raised.

Just a little more work to do on the snorkel and it should be ready for testing.

Wow :o
Brilliant!
