The uprated Stalwart ?
Dutch Walrus class SSK.
At a guess.
It's a BBQ in progress.
Thread drift...What is it?
Stuck on some rocks very probably.
The Andrew do have traditions to keep up you know.
A theme invoked by John Winton in ‘We Saw The Sea’, IIRC.Thread drift...
HMS Dolphin used to be the submarine base in Portsmouth. The approach to Portsmouth is narrow and complex, with shifting sandbanks and currents, narrow channels and other hazards (e.g. the Mary Rose), meaning the subs had to wait off-shore for the tides to be just right before approaching the harbour. If the sludge-skimmers misjudged the tide, they could easily end up on a particular sandbank. That sandbank became known as “Promotion Point”.
In terms of naval cock-ups, it was considered fairly minor; it was recognised as a very complex environment, there was no damage to the sub (it was on sand), and the next high-tide (twice a day) resolved the problem. However, it was still a grounding, and someone had to be punished, usually with a loss of seniority.
If you happened to be a submarine commander, who, unfortunately, had failed to gain promotion before becoming too senior for promotion, a grounding and resulting loss of seniority would put you right back into the promotion zone.
And, the next time they wanted to promote a sludgie, the admiral would look at everyone with the correct seniority, recognise the name for some reason and, as there would be no black marks in the candidate’s paperwork, conclude that the name was familiar because they’d heard something good about them. Therefore, they would be a good person to promote...
