The implication here, as I read it, is that some posters are in error. Can you explain why?

They always have lots of company when they transit past our place on Whidbey.

Re: Encounters of the Submarine Kind

Many posts here refer to surfaced submarines.

A French Navy submariner told me an interesting story. He was keeping watch at the periscope, at night and saw a vague white shape in the distance. Some time later, he looked again and the white shape filled the whole field of view. Looking up, he saw it was a sailing yacht without lights. He barely had time to retract the periscope and dive under the yacht.

If a collision had occurred, the periscope would have been bent but the yacht would have been holed.

When a submarine is training for special ops, it will often be not far from shore, close to the surface (periscope depth is about 1.5m of water over the top of the sail) without any light, and not operating a radar or transmitting on AIS. It will be running a radar detector and receiving on AIS. It is up to yachtsmen to be detected.

Which negates your first sentence. Hot dogging a sub is fun. It is done occasionally, without permission of course. Totally depends on the CO.

The last diesel electrics I saw were when I was in the Navy submarine service the late '60's.
I was crew on this boat, the USS Pickerel ss524 thankfully not on this day though !
That was a test for an emergency surface from maximum depth.

Looks like offshore of Pearl Harbor with the Koolaus in the background.

BTW I think this is the boat:
USS Dolphin - Maritime Museum of San Diego She is a DE that held all types of records in her "research" purpose. You can tour her in San Diego.
Just play the Grateful Dead real loud.

There is no discussion of classified material happening here. What specifically are you referring to?

Nonsense.

The Greenville incident in particular was a result of several factors aside from the CO but as a matter of course submarine CO's are definitely not "hot dogging" it.

Have you ever served on a submarine?

I wonder if he was on a diesel boat? That is not the case with a nuke boat.

The top of the submerged sail at PD would pose no danger to any sailboat at least in calm conditions.

That is a lot of lights all at the same time!
At some point, the correct answer becomes "a whole load of boats"

IIRC, he was on a diesel boat (a time when the French navy still had some of them).

Anyway, periscope depth isn't the same on all subs. At 2660 tonnes dived, the present French SSN (attack subs) are much smaller than the US ones (about 6900 tonnes dived for Los Angeles class). So, they have shorter periscopes.

Looking at it again, I believe it is the USS Jimmy Carter, the last of the three Seawolf class boats.

She was lengthened considerably and took over the tasks previously performed by USS Parche and USS Halibut. If you know what they did, you know the type of OPS she does.

If you want a good read about submarine OPS in the Cold War, read Blind Man's Bluff. Operation Ivy Bells is particularly amazing.

Or maybe a big, fat Russian sub; which poses a danger even if its 100 meters below the surface.

Re: Encounters of the Submarine Kind

Was once sailing in the adriatic and the depth went from 80m to 12m then to 5m then back to 12m then 80 again. Looked at my fish finder and it sure looked like the outline of a sub. Forgot to take a photo of the ff...
