Cutty Sark is a Britishclipper ship. Built on the River Clyde in 1869 for the Jock Willis Shipping Line, she was one of the last tea clippers to be built and one of the fastest, coming at the end of a long period of design development, which halted as sailing ships gave way to steam propulsion.
The opening of the Suez Canal (also in 1869) meant that steamships now enjoyed a much shorter route to China, so Cutty Sark spent only a few years on the tea trade before turning to the trade in wool from Australia, where she held the record time to Britain for ten years.[4] Improvements in steam technology meant that gradually steamships also came to dominate the longer sailing route to Australia, and the ship was sold to the Portuguese company Ferreira and Co. in 1895 and renamed Ferreira. She continued as a cargo ship until purchased in 1922 by retired sea captain Wilfred Dowman, who used her as a training ship operating from Falmouth, Cornwall. After his death, Cutty Sark was transferred to the Thames Nautical Training College, Greenhithe in 1938 where she became an auxiliary cadet training ship alongside HMS Worcester. By 1954, she had ceased to be useful as a cadet ship and was transferred to permanent dry dock at Greenwich, London, for public display.
The ship has been damaged by fire twice in recent years, first on 21 May 2007 while undergoing conservation. She was restored and was reopened to the public on 25 April 2012.[5] On 19 October 2014 she was damaged in a smaller fire.[6]
Construction

Cutty Sark was ordered by shipping magnate John Willis, who operated a shipping company founded by his father. The company had a fleet of clippers and regularly took part in the tea trade from China to Britain. Speed was a clear advantage to a merchant ship, but it also created prestige for the owners: the 'tea race' was widely reported in contemporary newspapers and had become something of a national sporting event, with money being gambled against a winning ship. In earlier years, Willis had commanded his father's ships at a time when American designed ships were the fastest in the tea trade, and then had owned British designed ships, which were amongst the best available in the world but had never won the tea race. In 1868 the brand new Aberdeen built clipper Thermopylae set a record time of 61 days port to port on her maiden voyage from London to Melbourne and it was this design that Willis set out to better.[7][8]
It is uncertain how the hull shape for Cutty Sark was chosen. Willis chose Hercules Linton to design and build the ship but Willis already possessed another ship, The Tweed, which he considered to have exceptional performance. The Tweed (originally Punjaub) was a frigate designed by Oliver Lang based on the lines of an old French frigate, built in Bombay for the East India Company as a combination sail/paddle steamer. She and a sister ship were purchased by Willis, who promptly sold the second ship plus engines from The Tweed for more than he paid for both. The Tweed was then lengthened and operated as a fast sailing vessel, but was considered too big for the tea runs. Willis also commissioned two all-iron clippers with designs based upon The Tweed, Hallowe'en and Blackadder. Linton was taken to view The Tweed in dry dock.
Willis considered that The Tweed's bow shape was responsible for its notable performance, and this form seems to have been adopted for Cutty Sark. Linton, however, felt that the stern was too barrel shaped and so gave Cutty Sark a squarer stern with less tumblehome. The broader stern increased the buoyancy of the ship's stern, making it lift more in heavy seas so it was less likely that waves would break over the stern, and over the helmsman at the wheel. The square bilge was carried forward through the centre of the ship.[7][9] In the matter of masts Cutty Sark also followed the design of The Tweed, with similar good rake and with the foremast on both ships being placed further aft than was usual.[10]
A contract for Cutty Sark's construction was signed on 1 February 1869 with the firm of Scott & Linton, which had only been formed in May 1868. Their shipyard was at Dumbarton on the River Leven on a site previously occupied by shipbuilders William Denny & Brothers. The contract required the ship to be completed within six months at a contracted price of £17 per ton and maximum weight of 950 tons. This was a highly competitive price for an experimental, state-of-the-art vessel, and for a customer requiring the highest standards. Payment would be made in seven installments as the ship progressed, but with a penalty of £5 for every day the ship was late. The ship was to be built to Lloyd's A1 standard and her construction was supervised on behalf of Willis by Captain George Moodie, who would command her when completed. Construction delays occurred when the Lloyd's inspectors required additional strengthening in the ship.[11]
Work on the ship was suspended when Scott and Linton ran out of money to pay for further work. Rather than simply liquidate the company, an arrangement was made for Denny's to take over the contract and complete the ship, which was finally launched on 22 November 1869 by Captain Moodie's wife. The ship was moved to Denny's yard to have her masts fitted, and then on 20 December towed downriver to Greenock to have her running rigging installed. In the event, completing the ship meant the company's creditors were owed even more money than when work had first been halted.[12]
Broadly, the parts of the ship visible above the waterline were constructed from East India teak, while American rock elm was used for the ship's bottom. The keel (16.5 in × 15 in (42 cm × 38 cm)) had on either side a garboard strake (11 in × 12 in (28 cm × 30 cm)) and then 6 in (15 cm) planking decreasing to 4.75 in (12.1 cm) at 1/5 the depth of the hold. Teak planking began at approximately the level of the bilge stringer. All the external timbers were secured by Muntz metal (brass) bolts to the internal iron frame and the hull covered by Muntz sheeting up to the 18 ft (5.5 m) depth mark. The stem (15 in × 15 in (38 cm × 38 cm)) and sternpost (16.5 in × 15 in (42 cm × 38 cm)) were of teak while the rudder was of English oak. The keel was replaced in the 1920s with one constructed from 15 in (38 cm) pitch pine.[13] The deck was made of 3.5 in (8.9 cm) thick teak while the 'tween deck was 3 in (7.6 cm) yellow pine. Her length was 212 feet 5 inches (64.74 m) with a draft of 21 feet (6.40 m) and a deadweight of 921 tons.[14]
Performance
A speck on the horizon
One day we sighted a vessel, a mere speck on the horizon, astern of us, and the way she came into view it was evident she was travelling much faster than ourselves. 'Bringing the wind up with her' was remarked on board, and that seemed the only feasible conclusion to arrive at and account for the manner in which she overhauled us. In a few hours she was alongside us, and proved to be the famous British clipper Cutty Sark, one of the fastest ships afloat. She passed us going two feet to our one, and in a short time was hull down ahead of us."
The maximum logged speed for Cutty Sark was 17.5 knots (32.4 km/h; 20.1 mph). The speed of a sailing ship is not so straightforward as a steamship, as winds vary and a ship must tack when sailing into the wind, both requiring the crew to make constant adjustments to sails, so her speed also depended greatly on the skill of her captain and crew. Her greatest recorded distance in 24 hours was 363 nautical miles (672 km; 418 mi) averaging 15 knots (28 km/h; 17 mph), although she recorded 2163 miles[clarification needed] in six days, which given the weather over the whole period implied she had achieved over 370 nmi (690 km; 430 mi) some days.[16] By comparison, Thermopylae's best recorded 24-hour distance was 358 nmi (663 km; 412 mi). Cutty Sark was considered to have the edge in a heavier wind, and Thermopylae in a lighter wind.[17]
Etymology
The ship's figurehead shows Cutty-sark, the nickname of the witch Nannie Dee who chases Tam o' Shanter, snatching his horse's tail before he escapes by crossing water
The ship was named after Cutty-sark, the nickname of the witch Nannie Dee in Robert Burns's 1791 poem Tam o' Shanter. The ship's figurehead, the original of which has been attributed to carver Fredrick Hellyer of Blackwall, is a stark white carving of a bare-breasted Nannie Dee with long black hair holding a grey horse's tail in her hand.[18] In the poem she wore a linensark (Scots: a short chemise or undergarment[19]), that she had been given as a child, which explains why it was cutty, or in other words far too short. The erotic sight of her dancing in such a short undergarment caused Tam to cry out "Weel done, Cutty-sark", which subsequently became a well known catchphrase. Originally, carvings by Hellyer of the other scantily clad witches followed behind the figurehead along the bow, but these were removed by Willis in deference to 'good taste'. Tam o' Shanter riding Meg was to be seen along the ship's quarter. The motto, Where there's a Willis away, was inscribed along the taffrail.[20]The Tweed, which acted as a model for much of the ship which followed her, had a figurehead depicting Tam o' Shanter.[21]
Cutty Sark was destined for the tea trade, then an intensely competitive race across the globe from China to London. Though the "premium" or bonus paid to the ship that arrived with the first tea of the year was abandoned after The Great Tea Race of 1866, faster ships could usually obtain a higher freight (the price paid to transport the cargo) than others.[2] Her first round trip voyage under captain George Moodie began 16 February 1870 from London with a cargo of wine, spirits and beer bound for Shanghai. The return journey, carrying 1,305,812 lbs of tea from Shanghai, began 25 June, arriving 13 October in London via the Cape of Good Hope.
Cutty Sark sailed in eight "tea seasons", from London to China and back.[2]
Competition from steamers
Cutty Sark's launch coincided with the opening of the Suez Canal to shipping. Her first trip encountered significant competition with steamships. The route from the Far East to London (and many other European ports) through the Suez Canal was shorter by about 3,300 nmi (6,100 km; 3,800 mi), compared to sailing round the Cape of Good Hope.[22] The route round Africa is in excess of 14,000 nmi (26,000 km; 16,000 mi). Typically a clipper might log significantly more than that by planning her route for favourable winds. Whilst it was possible for a sailing vessel to take a tug through the canal, this was difficult and expensive. Furthermore, sailing conditions in the northern Red Sea were unsuited to the design of a tea clipper,[23] so they still had to sail around Africa.
Less obviously, steamship design had taken a large step forward in 1866 with Agamemnon, using higher boiler pressure and a compound engine, so obtaining a large improvement in fuel efficiency. Ships of this type could compete with clippers before the Suez Canal opened.[23]
When the tea clippers arrived in China in 1870, they found a big increase in the number of steamers, which were in high demand. The rate of freight to London that was given to steamers was nearly twice that paid to the sailing ships. Additionally, the insurance premium for a cargo of tea in a steamer was substantially less than for a sailing vessel. So successful were the steamers using the Suez Canal that, in 1871, 45 were built in Clyde shipyards alone for Far Eastern trade.[2]
The numbers of tea clippers sailing to China each year steadily reduced, with many ships being sold and moving to general cargo work. Costs were kept to a minimum and rigs were often reduced to barque so that a smaller crew was needed.
Thermopylae
Cutty Sark's well known race against Thermopylae took place in 1872, the two ships leaving Shanghai together on 18June. Two weeks later Cutty Sark had built up a lead of some 400 nautical miles (460 mi; 740 km), but then lost her rudder[24] in a heavy gale after passing through the Sunda Strait. John Willis's brother was on board the ship and ordered Moodie to put into Cape Town for repairs. Moodie refused, and instead the ship's carpenter Henry Henderson constructed a new rudder from spare timbers and iron. This took six days, working in gales and heavy seas which meant the men were tossed about as they worked and the brazier used to heat the metal for working was spilled out, burning the captain's son. The ship finally arrived in London on 18 October a week after Thermopylae, a total passage of 122 days. The captain and crew were commended for their performance and Henderson received a £50 bonus for his work. This was the closest Cutty Sark came to being first ship home but it was Moodie's last trip as her captain before he transferred to steamships. He was replaced by Captain F. W. Moore.
Life at Sea
A little east of the longitude of the Cape we were favoured by a great fair wind blow, that tested all the resources of ship and crew. At the first spurt, heavy squalls came up from S.W., that threatened to take toll of our masts, but later it steadied down to a hurricane straight from the west.
Captain Wallace was sure in his element now. It was 'Stand by!' the whole time, not knowing whether the sticks would go, but the splendid rigging and equipment of sails in the Cutty Sark stood the strain. We lost two brand new topgallant sails and one lower fore topsail.
A tremendous sea was running and needs must we carry on or be pooped. The partial becalming of the lower sails by the stern seas was a great danger, as they filled again with a bang that threatened to burst them into tatters. It was some trick rebending sails. I had a time on the fore topsail yard for two hours. The ship took a green sea over the stern, and it appeared as if there were just three sticks set in the ocean, as it swept the length of the deck.
Moore remained captain only for one round trip to China, taking 117 days for the return trip. This was 14 days longer than Thermopylae and 27 days longer than achieved by the iron ship Hallowe'en a few months later. Captain W. E. Tiptaft assumed command in 1873 achieving 118 days on his first return trip, but after the ship had to travel 600 miles[clarification needed] up the Yangtze River in search of a cargo. Steamships were now taking most of the tea. The following year the return journey took 122 days, but on the outward journey Cutty Sark set a record time of 73 days from London to Sydney. In November 1877 the ship was anchored off Deal in the English Channel along with sixty other vessels, waiting out a great storm. The anchor failed to hold and Cutty Sark was blown through the ships, damaging two others before grounding on a mud bank. Fortunately she was pulled clear by the tug Macgregor before too much damage was caused and she was towed to the Thames for repairs.
In December 1877 the ship sailed from London to Sydney, where she took on coal for Shanghai, arriving there in April. However, the ship was unable to find any cargo of tea for a return trip to London—the days of the tea race were over. The master, Captain Tiptaft, died in October while still in Shanghai and was replaced by the first mate, James Wallace. The ship now had to take different cargoes around the world, including coal, jute, castor oil and tea to Australia.
In 1880 an incident occurred on board during which the First Mate Sidney Smith killed seaman John Francis. Smith was allowed to leave the ship at Anjer by Captain Wallace, causing the crew to cease work in protest. Wallace continued the voyage with six apprentices and four tradesmen but became becalmed in the Java Sea for three days. In desperation as matters moved from bad to worse, he committed suicide by jumping overboard and disappeared. He was replaced as Master by William Bruce, who proved to be a drunken incompetent who claimed pay for non-existent crewmen and managed to set sail with inadequate provisions, resulting in the crew starving. An inquiry in New York in April 1882 resulted in the captain and mate being suspended and replaced by Captain Moore, previously of Blackadder.
Wool trade

In December 1883, Cutty Sark departed Newcastle, New South Wales with 4,289 bales of wool and 12 casks of tallow, arriving in London in just 83 days. This was 25 days faster than her nearest rival that year and heralded the start of a new career taking Australian wool to Britain in time for the January wool sales.
In 1885 Richard Woodget was appointed captain on a salary of £186 per year and continued to improve on the fastest trip record, achieving 77 days on his first outward trip and 73 days returning to Britain from Australia. He achieved this by taking a more southerly route than previously, to catch the strongest winds in the Roaring Forties despite having to face icebergs, gales and storms whipped up by the winds he sought. Cutty Sark was the fastest ship on the wool trade for ten years. In July 1889 the log of the modern passenger steamship SS Britannia recorded that when steaming at 15–16 knots she was overtaken in the night by a sailing ship doing 17 knots, which proved to be Cutty Sark.
Eventually steamships began to dominate the wool trade too and it ceased to be profitable for a sailing ship. In 1895 Jock Willis sold Cutty Sark to the Portuguese firm Joaquim Antunes Ferreira for £1,250.[26] She was renamed Ferreira after the firm.[26] Her crews referred to her as Pequena Camisola (little shirt, a straight translation of the Scots cutty sark).[27]

The ship traded various cargoes between Portugal, Rio de Janeiro, New Orleans, Mozambique, Angola, and Britain. In May 1916 she was dismasted off the Cape of Good Hope because of the rolling of the ship in bad weather and had to be towed into Table Bay off Cape Town. Because of World War I, it was impossible to obtain suitable materials to replace the masts so she was re-rigged over 18 months to a barquentine sail arrangement.
In 1922 Ferreira was the last clipper operating anywhere in the world. Caught in a storm in the English Channel she put into Falmouth harbour where she was spotted by retired windjammer captain Wilfred Dowman of Flushing, Cornwall, who was then operating the training ship Lady of Avenel. The ship returned to Lisbon, where she was sold to new owners and renamed Maria do Amparo (Mary of the Refuge, a name associated with the devotion of Our Lady of the Refuge; in Portuguese, "Nossa Senhora do Amparo"). However, Dowman persevered in his determination to buy the ship, which he did for £3,750 and she was returned to Falmouth harbour. The rigging was restored to an approximation of the original arrangement and the ship was used as a cadet training ship. As a historic survivor, the ship was opened to the public and visitors would be rowed out to inspect her. Dowman died in 1936 and the ship was sold to the Incorporated Thames Nautical Training College, HMS Worcester at Greenhithe, leaving Falmouth for her last journey under sail in 1938. The ship was crewed by cadets, 15-year-old Robert Wyld steering the ship during the voyage.[28] Ian Bryce, DSC, the last surviving crew member on the historic journey from Falmouth to the Thames died, aged 89, on 11 December 2011.[29]
Cutty Sark and HMS Worcester as training ships, 1938.
At Greenhithe Cutty Sark acted as an auxiliary vessel to HMS Worcester for sail training drill, but by 1950 she had become surplus to requirements. From February to October 1951 she was temporarily moved first for a refit and then to take part in the Festival of Britain at Deptford. On 30 January 1952, the 800-ton tanker MV Aqueity collided with Cutty Sark's bow in the Thames. The two ships were locked together after the collision which forced Cutty Sark's jib boom into Worcester's fo'c's'le rails, snapping the boom before scraping along Worcester's starboard side. Cutty Sark's figurehead lost an arm in the process. Cutty Sark was anchored and towed to the Shadwell Basin where repairs were carried out by Green & Silley Weir Ltd. The damaged arm was recovered at Grays Thurrock and the figurehead was repaired.[30]

In 1954 she was moved to a custom-built dry dock at Greenwich.[31] She was stripped of upper masts, yards, deck-houses and ballast to lighten her before being towed from the East India Import Dock to the special dry dock at Greenwich. The skipper on this occasion was 83-year-old Captain C.E. Irving, who had sailed the world three times in her before he was 17. The river pilot was Ernest Coe. Thereafter the entrance tunnel to the dry dock was filled in, the river wall rebuilt and the work of re-rigging began. The foundation stone of the dry dock was laid by The Duke of Edinburgh, patron of the Cutty Sark Preservation Society, in June 1953. The restoration, re-rigging and preparation for public exhibition was estimated to cost £250,000.[32]
The ship is in the care of the Cutty Sark Trust, whose president, the Duke of Edinburgh, was instrumental in ensuring her preservation, when he set up the Cutty Sark Society in 1951. The Trust replaced the Society in 2000.[31][33] She is a Grade I listed monument and is on the Buildings At Risk Register. The gallery beneath the ship holds the world's largest collection of ships' figureheads, donated to the Society by Sydney Cumbers in 1953.[34]
The ship one week before the fire. Most of the upper sections had already been dismantled for renovation.Cutty Sark on fire
On the morning of 21 May 2007, Cutty Sark, which had been closed and partly dismantled for conservation work, caught fire, and burned for several hours before the London Fire Brigade could bring the fire under control. Initial reports indicated that the damage was extensive, with most of the wooden structure in the centre having been lost.[35]
In an interview the next day, Richard Doughty, the chief executive of the Cutty Sark Trust, revealed that at least half of the "fabric" (timbers, etc.) of the ship had not been on site as it had been removed during the preservation work. Doughty stated that the trust was most worried about the state of iron framework to which the fabric was attached.[35] He did not know how much more the ship would cost to restore, but estimated it at an additional £5–10 million, bringing the total cost of the ship's restoration to £30–35 million.[36]
After initial analysis of the CCTV footage of the area suggested the possibility of arson, further investigation over the following days by the Metropolitan Police failed to find conclusive proof that the fire was set deliberately.[37]
In a second incident on the morning of 19 October 2014, another fire broke out on the deck of the Cutty Sark. A small part of deck three and the hull timbers were damaged in the blaze. The London Fire Brigade managed to contain the blaze within an hour and she was reopened to the public shortly after.[6]
Damage
The day after the fire, 21 May 2007
Aerial video footage showed extensive damage, but seemed to indicate that the ship had not been destroyed in its entirety by the 2007 fire. A fire officer present at the scene said in a BBC interview that when they arrived, there had been "a well-developed fire throughout the ship". The bow section looked to be relatively unscathed and the stern also appeared to have survived without major damage; the fire seemed to have been concentrated in the centre of the ship. The chairman of Cutty Sark Enterprises said after inspecting the site: "The decks are unsalvageable but around 50% of the planking had already been removed; however, the damage is not as bad as originally expected."[citation needed]
As part of the restoration work planned before the fire, it was proposed that the ship be raised three metres, to allow the construction of a state-of-the-art museum space beneath. This would allow visitors to view her from below.[38]
There was criticism of the policies of the Cutty Sark Trust and its stance that the most important thing was to preserve as much as possible of the original fabric. Proponents of making her fit to go to sea advocated that the fire repairs be done in such a manner to enable her to do so.[39]
However, the state of the timbers, especially the keel,[40] and the fact that a hole had been cut through the hull in the 1950s for an access door, made this difficult. The Cutty Sark Trust said that less than five percent of the original fabric was lost in the fire, as the decks which were destroyed were additions not present at the original building.
The restoration work was criticised by The Victorian Society saying that the needs of the corporate hospitality market were put ahead of the preservation of the historic fabric of the ship.[41]Building Design magazine awarded the project its Carbuncle Cup for the worst new building completed in 2012 saying "The scheme's myriad failings stem from one calamitous choice: the decision to hoick the 154-year-old clipper close to three metres into the air on canted steel props."[42]
The design for the renovation project by Grimshaw architects with, during design development stage, newly established Youmeheshe architects and Buro Happold engineers involved raising the ship out of her dry berth using a Kevlar web, allowing visitors to pass under the hull to view it. Unfortunately it was discovered that the proposed web would not follow the reverse curves of the ship's hull which would effectively mask the hull's shape from view. An alternate design for the support of the ship had to be developed; this involved installing a deep steel belt around the hull tied by diagonal steel members passing through the hold to a new steel-reinforced keel. Horizontal tubular steel struts passing through the hold brace the diagonals apart while many of the corroded original hull frames have been doubled.
A new steelwork lower deck of contemporary design incorporating an amphitheatre feature was installed in the main hold while a glass-encased lift installed within the ship terminates in a new steel-and-glass housing structure on the weather deck. A second new steel-and-glass box has been installed above the forehold to enclose a new staircase. Access to the ship is through a new opening cut through the hull below the waterline in the ship's starboard quarter. The new access hole has required the addition of new steel framing. Visitors arriving on board the ship now do so via this entrance, which leads to the lower hold. Maldwin Drummond, Chairman of the Cutty Sark Trust, has explained in Classic Boat magazine's September 2010 issue the need to retain the spirit of the ship and he quotes the ideal that "The visitor should see the ship as though for some unexplained reason the crew had gone ashore". Doubts over the wisdom of Grimshaw's proposals have been raised by many ship conservationists including the Cutty Sark Trust's own engineer Peter Mason.[43]
Cutty Sark in February 2012, repairs nearing completion. The temporary cover which surrounded the ship during repair has been removed although workmen can still be seen on deck and in the rigging where not all yards have been replaced. Work was underway around the dock to lay new paving.
The project was costed at £25 million when it commenced in 2006 with £11.75 million of this total being provided by a grant from the Heritage Lottery Fund.[44]
Oscar-winning film producer Jerry Bruckheimer aided in the repair and restoration of Cutty Sark. A collection of photos taken by Bruckheimer went on display in London in November 2007 to help raise money for the Cutty Sark Conservation Project. The exhibition featured more than thirty pictures taken on set during the filming of Pirates of the Caribbean: At World's End.[45]
In January 2008, the Heritage Lottery Fund awarded the Cutty Sark Trust another £10 million towards the restoration of the ship, meaning that the Trust had now achieved £30 million of the £35 million needed for the completion of the project. In June 2008, Israeli shipping magnate Sammy Ofer donated the outstanding £3.3 million needed to fully restore the ship[46] although by January 2009 the London Evening Standard reported that the cost had risen further to £40 million creating a new shortfall.[47]
In February 2010, The Daily Telegraph reported the project cost had risen to £46 million with public money now being made available by London Borough of Greenwich to fill the funding gap.[48]
On 30 September 2008, the London Fire Brigade announced the conclusion of the investigation into the fire at a press conference at New Scotland Yard. The painstaking investigation was conducted by the Fire Brigade, along with London's Metropolitan Police Service, Forensic Science Services, and electrical examination experts Dr. Burgoyne's & Partners. They said that the most likely cause was the failure of an industrial vacuum cleaner that may have been left switched on over the weekend before the fire started. The report revealed no evidence that the ship was subjected to arson attack and concluded that the fire started accidentally.[49]
Physical evidence and CCTV footage of the fire showed that it probably started towards the stern of the ship on the lower deck. All electrical equipment on board was examined and it was determined that an industrial vacuum cleaner in this area was normally running continuously to suck up dust and particles from work going on to break up concrete within the ship. No one working on the ship had responsibility to ensure all equipment was turned off at the end of each day, and no one recalled switching off the equipment on the Friday in question. The vacuum cleaner has three motors inside and after the fire one was found to be burned out in a manner which suggested it had failed while operating. This was not conclusive evidence, however, because the motor might previously have failed in service without causing a fire, and gone unnoticed because the other two motors had continued to function. Tests on similar cleaners showed they had no thermal cutout devices and while they could run safely indefinitely if filters inside were clear, if the airflow through the cleaner was blocked then it would eventually overheat and could catch fire. This might occur if the cleaner were full of dust and debris. The cleaner had failed previously and two motors had been replaced.
On the basis of witness evidence, the joint investigation team considered it unlikely that the fire was caused by the hot work (welding) that was being carried out as part of the renovation or by carelessly discarded smokers' materials. No one had visited this part of the ship since work stopped on Friday evening, and it was considered unlikely that a fire could have smouldered all weekend before finally breaking out Monday morning. However, it was discovered that although all hot work was supposed to be recorded and someone was supposed to check afterwards to ensure of no fires, there was no record that such checks had ever been made, and on at least one occasion hot work had been conducted with no records made.
The ship was patrolled by two security guards, both of whom were supposed to patrol independently at least once an hour, or once every two hours later in the night, one being primarily responsible for the visitor pavilion and one for the dock. The guards were required to keep a log of their patrols, but after the fire the relevant page was found to be missing from the book. It was later found, already filled in reporting uneventful patrols of the site up to 7 am in the morning when the guards would have gone off duty. The alarm was raised when one of the guards called the fire brigade; before this the two reported that they had smelled burning plastic and had been investigating to try to determine its source.
A carpenter had visited the site on Sunday to collect some tools, but after 20 minutes attempting to contact a security guard to let him in, had climbed the fence, collected his tools and climbed out again. The carpenter reported that he had heard machinery operating towards the stern of the ship, but it was not clear whether this might have been the site diesel generator which ran at all times.
The ship was fitted with a temporary fire alarm system but it was unclear whether this had operated. A separate alarm within the pavilion did sound when smoke and heat reached that area, but the guards reported no ringing alarm before the fire was seen. Investigation afterwards discovered a faulty relay in the alarm panel which failed to switch power to the siren circuits when an alarm was triggered. However, the panel also contained a failed fuse in one siren circuit which suggested that the siren had activated but the fire shorted it out, and this might have also caused the relay to fail. The failed relay would have shut off power to the second siren circuit. Statements from workers suggested that weekly tests of the alarm system had not been carried out.
The original mast specifications as laid down by the ship's designer still exist and are listed below as "tea rig". This arrangement was used during the ship's time on the tea trade route, where it was necessary to maximise the area of sail to get the greatest possible propulsion when the ship might be becalmed in the doldrums. For the route to Australia it was not necessary to carry such a large area of sail and the masts and yards were reduced. The tradewinds required great strength in masts, but the wind could best be captured by relatively small, high sails. A smaller rig also represented a saving in maintenance costs. Each of the three masts (fore, main and mizzen) is in three overlapping sections.
