How embarrassing! Incontinent Lizzie doesn't Zoom and needs to become a Tena lady.
All to do with a ring on an inserted throbbing shaft causing the problem apparently.
Where OOF Lizzie's family have a strong navel history, I'm sure she will be along soon to give us all the intimate graphic details.
As others have said, this is such a non story it is almost laughable. My father used to talk about new Royal Navy ships going on sea trials and being "worked up" so that any faults could be seen and the crew could be trained to sail their new vessel. Faults were common, and when he joined HMS Fife, a then brand new "Devonshire" type guided missile destroyer in 1966 with systems that he had never seen before in the ships of "the old navy" as he called it (no port holes, and James Bond like control systems) there were faults. But this is common of all ships ever built, and especially those of the "new navies" of the 21st century. They are highly technical beasts, with mechanical, electrical and electronic parts that need to be tested, hence the extra special needs for sea trials. HMS Queen Elizabeth appears to have a simple propeller shaft gland issue that should be rectified quickly.
Faults at this time are expected, but it is crucial that when our warships are in battle they do not suffer those flaws. But even then, occasionally they will. You just hope it is not a major design flaw, such as with the K Class submarines, and the battlecruisers of WW1 & 2.
What should be of more concern is the future use of HMS Queen Elizabeth, and the morale of it's crew and the Royal Navy generally. Further Defence cuts will only exasperate the existing problems, just when we need our navy to be more powerful than ever.
