When she was designed for the Metropolitan Asylums Board the idea was to accommodate something like 750 boys on board and the Navy used her for 600 ratings, so there was room and to spare for the 200 Cadets who in, 1946, were regarded as a full complement for the ship. Worcester had four decks, apart from the hold, forecastle and poop. The hold was divided into storerooms by seven water-tight bulkheads, with and without doors, and many light bulkheads between the flats. Forward of the collision bulkhead was the coal bunker, abaft it the boiler room and engine room, all of which extended through the orlop deck above it. Then came the chain locker on the starboard side and the diesel generator and refrigerating plant on the port. Tanks for fresh water and diesel oil extended right across the ship. For the next 120 ft. of her length storerooms, with a centre-line alleyway between them, not only gave ample space for things needed on board but permitted everything to be arranged for constant inspection and easy issue. On the other side of a water-tight bulkhead special stores occupied another 30 ft. across the ship, then two very large fresh water tanks and the after peak. The orlop deck was above the waterline and, with the re-opening of the ports which were plated up by the Navy during the War, afforded plenty of light and air. Right forward the bunkers and engine and boiler rooms extended through the deck and abaft them were workshops and accommodation for crew. Then came the gymnasium, then the lower sleeping deck with hammock stowage leading out of it, 92 ft. long by the beam of the ship. There were nine classrooms, each entirely separate, although some had connecting doors, with up-to-date fittings and single locker desks so that the traditional Worcester book boxes, remembered by many generations of Cadets, were finally abandoned to their original purpose.
Forward on the lower deck was a large galley and abaft it, round the open space left for the capstan, were situated the victualling storerooms and pantry. Next came the Cadets' messroom, 51 ft. long by the full beam of the ship, with doors to the upper sleeping deck. Then the cabins of the warrant officer instructors occupied both sides of the ship except for the outfitter's shop on the starboard, after which is a range of bathrooms and toilets and, right aft, a sick bay 35 ft. long, with isolation ward, dispensary and a cabin for the sick berth attendant.
The library occupied the whole of the round bow on the main deck. It was comfortably furnished with arm and upright chairs, and had an excellent view of the river. The Cadet Captains' quarters - "the Cabin" by Worcester tradition - on the starboard side, was very different from the one right inboard in the old ship, and its counterpart on the port side was the tuckshop. Abaft that there was a clear space for recreation, running aft to the entry port and visitors' waiting room. This recreation space was decorated with a number of models and ship pictures and furnished partly with the old desks from the former ships with generations of initials carved on them.
Abaft the entry port the deck was narrowed by a range of cabins on either side and for this space the old name of "half-deck" was revived with the interpretation that it used to have in Drake's day. Divine Service was regularly held in this space, the after bulkhead being adorned by two war memorials. Leading out of it on the starboard side were a com-fortable warrant officers' mess and galley and some of the schoolmasters' cabins. On the port side were situated the officers' cabins and the Captain's office. Beyond the bulkhead on the starboard side was a big wardroom, accommodating both the officers and the schoolmasters, and a beautiful little chapel furnished with the fittings from the chapel of H.M.S. Iron Duke when she was Jellicoe's flagship. On the port side were the housekeeper's quarters, Captain's galley and some of the masters' cabins, the remainder, with that of the headmaster, being across the stern.
The upper deck, with the exception of the boatswain's store and radar room, was open to the elements, giving Cadets the opportunity for reviving the old Worcester custom of "slewing". On the stump mainmast was a 5-ton derrick with an electric winch. Under the forecastle were the quarters of the galley boys, the Cadets' washroom, showers and heads, while under the poop was a fine suite of rooms for the Captain. Over the former were located the carpenter's shop and tanks and over the poop the chart-house.
A platform for boat work was secured at a convenient height above the waterline along the port side, facing the shore; but except for one pair of davits for exercise purposes on the upper deck, all the boats were kept in the water. These consisted of two cutters, a jolly-boat, a second gig, a school gig, two racing gigs, two racing whalers and a motor boat, sufficient for all hands if it was necessary to abandon ship.
The headroom of 9 ft. 6 in. all over the ship was not only excellent for health but gave reasonable living spaces and recreational facilities. The messroom had ample space for all hands to eat at the same time at long tables with good elbow room. The Second and Third Officers sat at a head table with the Chief Cadet Captain permanently and two Cadet Captains by turn. The gymnasium also served as a games room with a piano against one bulkhead, plenty of space for ping-pong, billiards and other games and all the necessary fittings for the projection of talking films. There was also the added luxury of constant hot and cold water to the shower baths and tubs, much more numerous than they were in the old ship, and there was a washbasin for every two boys.
When the third Worcester was fitted out there was great discussion as to whether the Cadets should sleep in standee berths, after the fashion of American transports, or in hammocks which had been the custom ever since the ship was established. Hammocks won the day for a variety of reasons. They were slung in two flats, the forecastle and fore top Cadets on the lower deck and the main and mizzen Cadets on the orlop deck, the stowage being next to the hammock fiat in each case. Each Cadet still had his sea chest in the old way, but owing to the shortage and their lack of use to the modern apprentice when he went to sea, they were hired for the term instead of being provided by the Cadets' parents. In addition, each boy had a steel locker of the Navy pattern, put into the ship when she was commissioned at Scapa Flow.
The committee room, which was installed in the ship by the original owners, proved big enough to be divided into the wardroom and chapel. In addition, the Warrant Officers - instructors, carpenter, chief engineer, etc - had their own mess and the petty officers had single berth cabins, and the ratings two-berth.
The Captain's quarters were, naturally, under the poop and consisted of a large drawing room right across the stern, with a stern-walk facing downstream, dining room with pantry, etc., and four bedrooms, in addition to the Captain's own suite of a day room, bedroom, dressing room and bathroom.
Although the electric mains for the ship's lighting ran under water from the shore she had a diesel and three steam-driven generators, the former supplying D.C. current to the electric winch and all of them supplying the current for the pumps, ventilating fans and the lighting in case of breakdown of the shore supply. Two Scotch boilers burning coal supplied the ship's heating and hot water.
Although the fire danger was not as great as it was in the old wooden ship, every sensible, seaman-like precaution was taken and mains were laid on all decks. Seventy tons of water could be drawn at once from the gravity tanks, in addition to that delivered by the pumps in the engine room. Fire extinguishers were to be found everywhere and routine fire drill was held regularly, together with boat drill and "abandon ship" practice. The greatest care being taken to prevent the drills becoming an ordinary routine.
