Thanks for that Nopileo.

I have not yet received radar but from what I have read, I want to be ready. Also enjoyed reading some of the ways to improve crash diving by running decks awash and using snorkel. Neat.

Good idea to PM Jungman and get him to link Sensorpak. If 43+ is that bad then a lot of people are going to be needing his pack.

Salute

Survivors from 3 different boats reported that poisonous fumes entered the submarine due to Schnorkel mis-functioning (I wonder how many boats sunk without survivors had the same problem). Another boat had to break-off her patrol because she was unable to retract the Schnorkel, even manually.

The snort was unable to operate correctly in rough sea's as the diesels exhaust pressure could only overcome approx 0.5M of water above it when that increased to approx 1 Metre or more the back pressure on the exhaust forced the relief valves inside the boat to open and then the CO was dumped inside the boat until the outside pressure was reduced.

To reduce huge pressure fluctuations in the engine room the bulkhead hatch was left open to the rest of the boat this ensured the diesels could breath air from the boat without being starved while the snort dropped below the water line. This also ensured CO moved freely about the whole boat as well.

I received a response from Jungman. He has not made a dedicated thread for the SensorPak yet, as he's still working on it, so that is good news. :yep:

i read that if you used the Snorkel in the Real UBoats you couldn't travel faster than 6sm. In SH3 you could travel at AK :-)

In a Type VII I think up to 8Knots was acceptable but less than that would have been normal.

From memory up to 13 Knots is possible BUT bad things start to happen - One thing from memory is some sort of resonance sets up with the periscope housing not to mention damage directly to the Snort in heavy seas and high speeds.

Probably 6Knots would be considered a nice top speed for Snorkel travel, much over that is fantasy land.
