I had three DE A boats, they all leaked, Artemis was the worst and proved it by sinking just after I came off her for demob.
Who remembers the joys of pooping on an A boat, no Elephants foot rigged just a full bore entry down the Conning Tower hatch, diesels going full bore and the vacuum trying to pull your eardrums out.
I brought the Amphion home from Singapore, exercising with the Yanks off Panama they hit us with a practise Asroc, that was the last time she dived as the foreplanes gave up the ghost and had to be secured by a wire strop to stop them flapping around. We already had 4 x 4 lengths of timber from the deckhead to the cylinder heads on the donks because the cylinder head bolts had started sheering off.
On the Alaric off of San Juan, one of the Props fell off and they had to fly another one out from Canada to replace it.
P & O Boats were drier, but to be fair a lot younger than the A's when I joined them.
Ah! the joys of being a Submariner in the '60's
