US judge reinstates sonar curbs

As a thought. With the different layouts over the years does anybody have their favourite dit of skinned knuckles or bashed forheads when trying to reach those 'oh so out of the way valves' to isolate when tagging out Here's mine.
EHS 101 in the fwd cab space on a T boat was my favourite. Well hidden behind a work top or two and a T frame and only reached by popping down the bomb shop and getting some friendly fore endies to stetch your arms about another twelve inches first.

The fun starts then, leaning right over you find the valve, small and painted brown in among other small brown valves and you start to turn......and turn......and turn...and turn....and turn.....then they pipe leave and you're still turning and gasping for air. Finally it's shut and isolated (after about thirty turns, could be more)...then you get back up to find the designated red trafalite tally in the tag out box and lean in again to tie it on with a bit of brown string. Only tying it on requires TWO hands and there definitely isn't room for two hands in the space provided.

Anyway you achieve the aim and get back to the CR to find a waiting Wrecker asking how come it took you so long and 'have you been getting punchy on two deck' when he points at your knuckles...skinned and bleeding!

The whole boat has been tagged out for divers and where is the work to be done. They want to put a blank on number No1 MBT starboard because the main vent is passing and needs tweaking (open, clean around the seal and shut. For the non quals). The divers are working fwd and we are starboard side to (with all the cats and whatnot in the way) and will go no where near back aft BUT the whole boat has been isolated to make sure they stay safe because as we know the water in Guzz dockyard is crystal clear out to fifty feet and it's impossible to get disorientated!!!! :skull:

The brief from the OOD beforehand...'don't squish any of the divers...The paperwork will be a nightmare'!

The only time I have ever heard the term 'Crazy Ivan' is in that movie 'Hunt for Red October'. We in the real world call it 'clearing stern arcs'.

Note: 'stern arcs' - not 'baffles'

As for the environmentalist belief that active sonar kills the whales - Bullshit IMHO.

What would you Australians know anyway?

IDID, are you referring to the final line of Jack's post, or all of it.

Furthermore, one still has to clear stern arcs even with TA fitted

Actually Joe Crow I was insinuating that Australians know little or nothing about anything whatsoever! :thumright:

Even with a towed array fitted you still need to clear stern arcs, really? I never knew that!

Have a nice day

I knew you knew, I didn't know if you knew Jack77 knew, I didn't know if Jack77 knew you knew, I know several of our fellow forumites don't know, but I don't know whether you knew I knew all I know.

So why the towed array.. Passive and long enough to reduce the need for clearing stern arcs.

But what do I know I was a target :thumright: :thumright:

The bearing accuracy fwd and aft on TA is veryyyyyyyy iffy to say the least. Harry Joe skips likes to clear stern arcs and satisfy himself that any of the TA contacts are not within broadband range. If they are, KALMAN usually gives him a working reliable solution for ranging.

Also during CSA's ,when the TA is straight then those contacts that were on the bow or in the stern are then on the beam and a much more accurate bearing and range can be eaked out, not always though but it usually works.

Inducing doppler into a frequency works wonders for peace of mind in the CR and it makes them all smug and superior, particularly when they think they're driving the solution.

Errrm as I said ranging!

Many apols Idiotdeeper.
I my youth I was forced by my sea dad to ingest SMP4 - 5- 6, all the US under ice publications (NWP's) ADH and the Supp, The fighting instructions AND Binder Nine of NISUMS. I was always escorted to the JR's heads to do domestics because they couldn't be sure that the macerator would mash the jobbies properly. At least that's what they said....cos I was a bit skin in those days! Brass screws still give me grief and I stopped eating them one thousand years ago! :tp: :toilet: :whew:
