Royal Navy support sailors vote to strike - and it 'could put security at risk'
The Nautilus union balloted its members over strike action after they received a 4.5% pay offer - well below last year's inflation rate.

How do I change this 'custom title' thing then?
I think from ship plotter they were going out on a relocation trip. It’s not our normal AWLB.

Believe it or not:
The Germans started it during WW1 but the British took it further also, the French and Italians and Japanese in WW2 had a good-go at the idea!

This perhaps belongs in Science or Theory, but I was just wondering how early in shipbuilding history was the Archimedes Principle accepted as undeniable fact. I’m asking because for warships in particular, the advantages of a metal hull in the days of cannon ball naval fighting are all too . Was metal in such short supply before the 19th century to prevent even the richest and most powerful nations to build their ships’ hulls out of metal?

No, it wasn't the cost as such but a problem with developing technology - that is, the ability to roll, consistently, large plates of a suitable steel.
See also HMS Warrior ... [Warrior is riveted steel plates with double diagonal oak baulks on the inside ; she was built at Thames Ironworks in 1859/61 in response to the steam-powered French iron clad / wooden-hulled "Gloire" - have a look here at the wikipedia ... HMS Warrior (1860) - Wikipedia]
second point was that cannon balls hitting steel plates - or timber - will cause splinters to spall off the interior surface, even if the ball doesn't penetrate full thickness.
{I first met Warrior when she was under restoration in Hartlepool, during the early 1980s, and she made quite an impression !}

Don’t forget the barnacles and Brunel.
Copper bottoms reduced marine growth..you can’t fix copper to iron without making a big battery and causing a whole load of galvanic corrosion.
“Initially copying wooden construction traditions with a frame over which the hull was fastened, Isambard Kingdom Brunel's Great Britain of 1843 was the first radical new design, being built entirely of wrought iron. Despite her success, and the great savings in cost and space provided by the iron hull, compared to a copper-sheathed counterpart, there remained problems with fouling due to the adherence of weeds and barnacles. As a result, composite construction remained the dominant approach where fast ships were required, with wooden timbers laid over an iron frame (Cutty Sark (1868) is a famous example). Later Great Britain's iron hull was sheathed in wood to enable it to carry a copper-based sheathing. Brunel's Great Eastern (1858) represented the next great development in shipbuilding. Built-in association with John Scott Russell, it used longitudinal stringersfor strength, inner and outer hulls, and bulkheads to form multiple watertight compartments. Steel also supplanted wrought iron when it became readily available in the latter half of the 19th century, providing great savings when compared with iron in cost and weight. Wood continued to be favored for the decks.”
“While anti-fouling coatings began to be developed from 1840 onwards, the first practical commercial anti-fouling coatings were established around 1860.”
Which, of course, was WARRIOR’s year of construction.

Of course, Brunel’s father, Marc, had previously massively increased the rate at which ships could be built…
“Brunel approached Samuel Bentham, the Inspector General of Naval Works. In April 1802 Bentham recommended the installation of Brunel's block-making machinery at Portsmouth Block Mills. Brunel's machine could be operated by unskilled workers, at ten times the previous rate of production.[9]Altogether 45 machines were installed at Portsmouth, and by 1808 the plant was producing 130,000 blocks per year. Unfortunately for Brunel, the Admiralty vacillated over payment, despite the fact that Brunel had spent more than £2,000 of his own money on the project. In August 1808 they agreed to pay £1,000 on account, and two years later they consented to a payment of just over £17,000.”

Any operational reasons why Royal Navy sailors aboard HMS Diamond are dressed like James Bond supervillain henchmen?

Sasaferrato may tell you something about this, if he feels up to it and you are very privileged, harrowing as hell.

I imagine they train from time to time.
I don't know though, my involvement with the military ended when I left the SAS, a time of my life I NEVER talk about. NEVER.
