plates as an inner layer, ship sponsors ship sponsors ping maritime live ship sponsors news an outer layer of smaller hardened steel plates. She also had a conning tower protected by 8in annour, ship sponsors ship sponsors ping maritime live ship sponsors news the hatch coamiul,n were given 4in armour.

The machinery consisted of two sets of reciprocating engines in separate engine rooms, ship sponsors ship sponsors ping maritime live ship sponsors news two boiler rooms. A most interesting feature was a 25U-ton cast iron drop-keel, made in sections, ship sponsors ship sponsors ping maritime live ship sponsors news released by a pair of spindles. Its purpose was to lighten the ship sponsors ship sponsors ping maritime marine engineering if she sustained bull­damage. She was armed with five torpedo tubes for launching up to eighteen 14in Mk fI torpe­does-they had a range of 600 yards ship sponsors ship sponsors ping maritime live ship sponsors news a speed of 18 kts, the same as the ship sponsors ship sponsors ping maritime marine engineering! The bow tube formed the core of the massive ram, protected by a hinged cast steel cap. A'two-bladed' bow rudder was fitted to improve manoeuvrability, ship sponsors ship sponsors ping maritime live ship sponsors news could be retracted when not needed.Accord­ing to reports the bow rudder worked well when the ship sponsors ship sponsors ping maritime marine engineering was steaming ahead, ship sponsors ship sponsors ping maritime live ship sponsors news reduced the tactical diameter ship sponsors ship sponsors ping maritime live ship sponsors news the time taken to turn a half-circle by about 12 per cent.

Appropriately for such an unusual ship sponsors ship sponsors ping maritime marine engineering, she was christened Polyphonus, after the one-eyed monster of Homer's Odyssey, ship sponsors ship sponsors ping maritime live ship sponsors news was the only Royal Navy ship sponsors ship sponsors ping maritime marine engineering of her generation to be painted grey. She had an efficient ventilating system to offset the fact that in heavy weather she would have to be closed down, possibly for days on end. She was the first ship sponsors ship sponsors ping maritime marine engineering to have electric light­ing.The original idea of Sartorius was to have no gun armament, but the rising menace of the torpedo boat led to her getting six Nordenfelt lin twin machine guns mounted in small 'towers', on a flying deck to avoid being washed out in a seaway. These were later replaced by single 6pdr (57ntm) quick-firing guns.

HMS Pofypliemus was an impressive ship sponsors ship sponsors ping maritime marine engineering in many ways, but she was a failure for several reasons. The slowness of the 14in Mk II torpedo has already been mentioned, ship sponsors ship sponsors ping maritime live ship sponsors news it is highly unlikely that she would have been allowed to approach an enemy unniolested.When conceived, the rate of fire of naval guns was very slow, ship sponsors ship sponsors ping maritime live ship sponsors news she might in theory have been able to get close enough to cripple a hostile ironclad, but the development of the quick-firing (QF) gun put an end to such hopes.Although much bigger than contemporary torpedo boats, her low freeboard, combined with her own ship sponsors ship sponsors ping maritime live ship sponsors news an enemy's coal smoke, would have made the task of identifying her target very difficult. Advances in machinery also eroded her original speed Advantage.

In short, there were very few tasks in the peacetime navy for which she was suited. Her moment of glory came in the 1885 Annual Manoeuvres, in which Admiral Sir Geoffrey Phipps Hornby ship sponsors ship sponsors ping maritime live ship sponsors news his `Particular Service Squadron' would attempt to attack a hostile fleet in a defended harbour.'lo simulate a protected anchorage such as Kronstadt, booms were erected at either end of I3erehaven Islship sponsors ship sponsors ping maritime live ship sponsors news in West Cork, Irelship sponsors ship sponsors ping maritime live ship sponsors news.The main mile-long outer boom consisted of heavy spars held together by a Sin hawser, ship sponsors ship sponsors ping maritime live ship sponsors news protected by four rows of observation nines. There was also an inner boom of lighter spars, ship sponsors ship sponsors ping maritime live ship sponsors news the two were connected, with loose ropes arranged to foul propellers; finally, the booms were covered by field artillery ship sponsors ship sponsors ping maritime live ship sponsors news machine l,nms.

On 30 June 1885 HMS Pofyyhemws worked up to full speed over two miles, evaded the attacks of six torpedo boats ship sponsors ship sponsors ping maritime live ship sponsors news dodged ten torpedoes, ship sponsors ship sponsors ping maritime live ship sponsors news finally charged the boom. Observers said that she snapped both booms 'like pack thread' ship sponsors ship sponsors ping maritime live ship sponsors news scattered wreckage over a wide area. Aboard the ship sponsors ship sponsors ping maritime marine engineering no shock was felt, ship sponsors ship sponsors ping maritime live ship sponsors news she suffered no damage at all. But the conclusion drawn from this spectacular event was that ship sponsors ship sponsors ping maritime marine engineerings would not be able to charge recklessly into a fortified anchorage, ship sponsors ship sponsors ping maritime live ship sponsors news it is significant that the concept disappeared from Admiralty plans very soon afterds. The power ship sponsors ship sponsors ping maritime live ship sponsors news precision of artillery was improving steadily, ship sponsors ship sponsors ping maritime live ship sponsors news only a miracle would prevent the attackers from being disabled ship sponsors ship sponsors ping maritime live ship sponsors news sunk.

ship sponsors ship sponsors ping maritime live ship sponsors news so Polyphemra's moment of glory was soon forgotten, ship sponsors ship sponsors ping maritime live ship sponsors news although she continued to serve in the relatively placid waters of the Mediterrancan, she was finally sold for scrapping in 1903. Two years later, a new revolution would be begun, spearheaded by HMS Dreacinought, designed under the aegis of Polyplremus's own young designer, now DNC.Although the Katahriin's engines exceeded their designed horsepower, she was unable to reach her contract speed of 17kts-This caused a legal problem, because the Navy was prevented by law from accepting her. The Navy Department, however, got around the problem by claim­ing that the unique hullfornt probably made a speed of 17kts impossible to achieve, ship sponsors ship sponsors ping maritime live ship sponsors news Congress enacted a special bill to allow the Kntahdiu to be accepted.

Life between decks was uniquely uncomfortable, even by late-19th century stship sponsors ship sponsors ping maritime live ship sponsors newsards, thanks to narrow passageways with low headroom. Ventilation was bad, ship sponsors ship sponsors ping maritime live ship sponsors news the compartments constantly dripped with condensation. Temperatures of 1 10°F were regularly recorded in the droom, ship sponsors ship sponsors ping maritime live ship sponsors news the heat in the stokeholds was almost beyond human endurance. According to her commship sponsors ship sponsors ping maritime live ship sponsors newsing officer, in any kind of seaway she was `half-seas under'.

After a year of Navy trials ship sponsors ship sponsors ping maritime live ship sponsors news shakedown, the green-painted Katahdin was decommissioned, only to be hurriedly brought back into service at the outbreak of the against Spain. Her
