However, by the time the plant opened the war was over and its manufacturing techniques outdated. It was taken over by Brunner Mond in and manufactured synthetic ammonia and fertilisers. In anhydrite was mined from below Billingham for use in the making of sulphuric acida necessary component for the manufacture of detergents and fertilizers.

Another chemical plant was established the following year to make oil and petrol from creosote and coal by a process called hydrogenation.

In another large chemical works opened on Teesside at Wilton[28] on the south side of the River Tees. Further lands were purchased by ICI in at Seal Sands, where land had been reclaimed from the sea, becoming the third large-scale chemical manufacturing site on Teesside.

Nylon 66 manufacture ceased on Teesside in with the closure of the Invista manufacturing unit. Petrochemical production[ edit ] Coke ovens used in the production of chemicals at Billingham were replaced in by plants using the steam naphtha process, which enabled the use of crude oil as feedstock for the process known as cracking.

This proved to be a much cheaper way to produce ethylenearomaticspetroleum derivatives and other chemicals such as ammonia. From to four large oil refineries were erected at the mouth of the Tees, two by Phillips Petroleum and one each by ICI and Shell.

Their main purpose was to supply the Billingham chemical industry. Salt making[ edit ] Salt-making in and around Greatham between Hartlepool and Billingham had been important in Roman and medieval times, [30] [31] and salt was also produced on Wearside from the s, but by the 16th century the industry had been eclipsed by South Shields on the Tyne.

The works was later purchased by the famous salt-making company Cerebos in By the midth century, Cerebos was owned by the food conglomerate Rank Hovis McDougalland the factory closed in Today the Huntsman Tioxide is based close to Greatham, operating one of the world's largest chemical plants for the manufacture of titanium dioxide which is the brilliant white pigment used in paints, Polo mints[ citation needed ], cosmetics, UV sunscreens, plastics, golf balls and sports field line markings.

Sunderland was also rising to prominence as a glass-making centre, with James Hartley's Wear Glass Works opening in [37]and by one third of the sheet glass in England was supplied by his Sunderland works. The Candlish Glass Bottleworks was the largest in Europe, managed by John Candlish Coal mining[ edit ] Wynyard Park circa now a fine Country House Hotel, Wynyard Hall Coal mining was one of the first industrial activities in Northeast England because the region was fortunate to have shallow seams of coal near the coast, which meant that material could be transported in and out by sea.

The energy from coal underpinned the development of many of the industries around these ports. As discussed in the classic historical review of "Victorian Cities" by Asa BriggsMiddlesbrough was developed as a port downstream of Yarm and Stockton to take bigger coal ships.

For example, Seaham is a port community that was developed to handle output of the coal mining interests of Charles William Vane-Tempest-Stewart the 3rd Marquis of Londonderrya military leader and business man who became one of the UK's richest men due to his coal mining developments.

The Marquis also built one of the country's finest country houses in the region as a palace for his family and his royal connections.

It is called Wynyard Hall [43]. London was one of the places which received coal from the area and there are references to shipments of coal being sent to the capital, for example cauldrons of coal from Tyneside to London in for smiths involved in building Windsor Castle.

Before the growth of mining companies the coal from the North East was often sent to London using monks. The coal was often called sea coal because it often washed up from undersea outcrops on the Northumbrian coast. This could explain the name Se-coles Lane in London. Improvements in technology meant equipment could be built to go deeper than ever before.

One example was the High Main seam at Walker Colliery on Tyneside, which became one of the deepest coal mines in the world, thanks to large engine cylinders which helped drain the mine. Miners in the cage ready for their descent, Monkwearmouth Colliery, Sir Humphry Davy, after contemplating a communication he had received from Reverend Dr Robert Gray Rector of Bishopwearmouth later Bishop of Bristol regarding the problem of gas in mines, took up the challenge of solving the problem of providing light in " fire-damp " ridden collieries.

He started the work with several days of discussions with John Buddle, the overseer at Wallsend Colliery, other colliery owners and finally the Reverend John Hodgson, Vicar of Jarrow. Davy also collected samples of "fire-damp" before returning to his laboratory in London. Two designs of his lamps emerged and were tested at the most hazardous pits in the country, then at Newcastle-upon- Tyne and Whitehaven in Cumberlandand were a resounding success.

He later published his paper on "The safety lamp for coal mines and some researches on flame" inwhich made underground coal mines much more safe.

George Stephenson a colliery engineer at Killingworth Main Colliery also invented a safety lamp which was successfully tested on 21 October This became known as the "Geordie" lamp. As a result, some in the Northeast then tried to challenge the delivery of some Ceremonial Plate to Davy but the Davy Lamper's won the day and on 25 September a dinner service as presented to Davy from the coal owners at the Queen's Head in Newcastle.

Davy declined to take out a patent on his lamp design effectively giving it to the nation and the world's coal miners. I said to those around me: It was located on the north bank of the River Wear and was the largest pit in Sunderland and one of the most important in County Durham. The mine opened in and was the last to remain operating in the Durham Coalfield, with the last shift leaving the pit on 10 December and ending over years of commercial underground coal mining in the region.

C's Stadium of Light which opened in July The mine is commemorated by a large sculpture of a miners lamp at the entrance to the stadium. The Durham Coalfield remains a national resource for the UK economy today and for the future.

Most of the mines in the region were closed during the years of UK Prime Minister Margaret Thatcher see UK miners' strike — however several large open cast coal mines are still operational in the region. Today companies like Five-Quarter are investigating the use of the latest technology for underground coal gasification to access the Durham Coalfield reserves.

Professor Paul Younger of Newcastle University in reported [48] that "Around 75 per cent of the coal in the North East is still underground, even though we have been mining it on an industrial scale longer than anyone else in the world.

Previously a lot of this coal was too deep for conventional mining, or too far off shore. Even today this resource this could never be exploited by conventional means, but the technology to harness that resource has now become cost effective. In iron ore was discovered in the Cleveland Hills near Eston to the south of Middlesbrough and Iron gradually replaced coal as the lifeblood of Eston.

The ore was discovered by geologist John Marley and first utilised by John Vaughan, the principal ironmaster of Middlesbrough who along with his German business partner Henry Bolckow had already established a small iron foundry and rolling mill using iron stone from Durham and the Yorkshire coast, with the new discovery prompting them to build Teesside's first blast furnace in Iron was in big demand in Britain in the late 19th century, particularly for the rapid expansion of the railways.

More and more blast furnaces were opened in the vicinity of Middlesbrough to meet this demand such that by the end of the century Teesside was producing about a third of the nation's iron output. In Hugh Reid Liberal politician described how "The iron of Eston has diffused itself all over the world.

In the post-war boom saw Dorman-Long build a state of the art steelworks at Lackenby and then new blast furnaces at Clay Lane. The history of Teesside and its rapid growth during the 19th century is directly linked to the expansion of the railways from Darlington and Stockton towards the mouth of the Tees estuary and the subsequent discovery of ironstone in the Cleveland Hills which attracted iron companies to the area.

With records of associated institutions such as the Middlesbrough Exchange Co. Ships were built on the River Wear at Sunderland from at least and on the River Tees at Stockton from at least[56] with the Northeast of England more generally being the birthplace of some of the world's greatest vessels. This was recognised in with the regions shipbuilding heritage and global impact being recognized by UNESCO and placed on their Memory of the World Registerranking the regions shipbuilding heritage alongside iconic items such as the Domesday Book in terms of historical importance.

Ships were built across the region, especially along Tyneside in Jarrow and Wearside in Sunderland and also in smaller ports like Blyth, Whitby and Hartlepool. Sunderland's early development was due to coal but it later transitioned to become the largest shipbuilding town in the world [58] giving the town its fame.

The first recorded shipbuilder was Thomas Menville at Hendon in By there were 65 shipyards such that over wooden vessels were built at Sunderland in At this time 2, shipwrights worked in the town and some 2, others were employed in related industries. Sunderland's first iron ships were built from and wooden shipbuilding ceased here in Shipbuilding did not begin in Middlesbrough until when a wooden sailing ship called The Middlesbro' was built.

Teesside's first iron ship was built in Thorneby init was a screw steamer called The Advance, and Teesside's first steel ship was Little Lucy built in Afterwards, in a clockwise direction, it heads over to Europe before splitting into two parts, one of which head north towards Europe and the other towards the coast of Africa. For the crews taking part in the EDS Atlantic Challenge, negotiating this current is a highly strategic affair.

The boats which opted to go north, as Kingfisher did, decided to sail along the coast where the current is much weaker. But there is an element of risk in terms of tactics with this option: AS things have turned out, this strategy seems to be paying off since the boats are sailing at very similar speeds, at an average of around 10 knots. The actual manoeuvre involves turning the boat so the stern moves through the wind, the sails come crashing sometimes across to the other side of the boat, and the boat heads off in the other gybe with the wind on the other side of the boat.

A gybe for the solo sailor, in any kind of breeze, is a dangerous manoeuvre, but they have no choice! The worst case is an accidental gybe under autopilot The indexsail bangs across as the wind catches the other side of the sail. Not easy out there! More on that one later! Health on board It's not easy coming back from a week at sea without some knocks and bruises.

It's no surprise to anybody: And keeping one's balance on a boat thrown around by the waves is sometimes more akin to a bout of boxing. From a simple bruise to a fracture, knocks are frequent and the faster the boat, the more they are violent.

It's a struggle against gravity, but also against the cold and damp. Wrapped up in a foul-weather suit, a sailor might be warm, but one sweats.

And the rubbing of clothes on damp skin causes irritation, even boils. Another enemy is the lack of sleep. Whether single-handed or as a crew, the sailor rarely sleeps comfortably and for long enough. Even if they are used to this sort of out of phase rhythm, certain people can find it difficult recuperating, notably because of the stress, the cold and the noise.

History of multihulls While the first multihulls were imagined by the Polynesians hundreds of years ago, the ancestor of current day multihulls dates from Designed by Nat Herreschoff, this revolutionary catamaran had a centreboard and a rudder on each of its hulls, and a central pod, and was capable already of reaching a speed of 18 knots. InManu Kai, the first modern multihull, saw the light of day, and the 50s saw an explosion of dinghies and small beach cats in plastic.

The trimaran, with its three hulls made a comeback in with Pen Duick IV. But multihulls didn't steal the scene untilwith Elf II and the start of the "carbon" era.

Today, the no-limits race called simply The Race gave birth to a new era of giant multihulls of over 30 metres long capable of reaching incredible speeds the record going to Innovation Explorer with The 'Apparent' Wind would be zero.

If you are on a boat at that time, there would be no pressure on the sails and you would slow down. If at that time you headed left 30 degrees, you would start to feel apparent wind on you, and you would go faster. That is sailing a 'hotter angle', it's a choice between going where you want to go slowly, or heading up in to the wind and going faster! It gained official ISAF recognition as an international class inbringing together the best skippers in the world and is headed by Christophe Auguin.

One of the index requirements is the self-righting capacity of the boats.

Critical support for the solo sailor when they are forced to scale the towering carbon fibre masts. Boat speed is measured in knots. Now If you have ever stuck your head out of the sun roof going along at 40 miles per hour - that's windy - do it when it's raining and you might get some idea of what its like for the skippers!

Not that we are advising this. They are adjustable, and are used to hold the boom up off the deck and coachroof when the sail is not fully powered up in which case the shape of the sail essentially holds the boom up on its own.

Last night Nick had the indexsail all the way down, and when the boat was rolled the force of the water on the boom and stacked indexsail will have easily been enough to break them. In fact the jammer that they are secured with ripped off the boom rather than the lines breaking themselves, so Nick was able to temporarily re-tension the lazyjacks and secure the line on the winch at the mast.

Kartenskizze Manouvres Manoeuvring at sea, whether it's on a monohull or a multihull is similar: Meridians - On the globe, lines of constant longitude extend from pole to pole, like the segment boundaries on a peeled orange. Every meridian must cross the equator. Since the equator is a circle, we can divide it--like any circle--into degrees, and the longitude angle of a point is then the marked value of that division where its meridian meets the equator.

What that value is depends of course on where we begin to count--on where zero longitude is. For historical reasons, the meridian passing the old Royal Astronomical Observatory in Greenwich, England, is the one chosen as zero longitude. Today, the Mini 6. There are two types of Minis: To be recognised as a production Mini by the class, ten strictly identical examples of the boat must have been built.

The index technical characteristics: Monohull to Trimaran Apart from their length 60 ft or The former is almost as wide as she is long with As for weight, it's quite surprising, even though the monohull is smaller than the multihull, she is heavier, weighing in at 8.

Simply because of the ballast, or keel if you like, that the monohull needs to indextain its stability in the water. A stability that the multihull has naturally with her three hulls.

In the time of a crisis, it is the MRCC that manages all the rescue actions and recieves the emergency position signals.

Calculating one's position Making a sailing boat go is one thing, but taking it to a precise point by following a chart is another. That's what we call celestial navigation. For this they used a sextant, an instrument that enabled them to measure the height of a star from the horizon and calculate their position. Today, many skippers take a sextant with them, because if they have an electronics failure, it becomes an indispensable piece of equipment. The heading and the course. Once he knows his position on the chart, the sailor can determine what heading to follow to arrive at the desired point.

For this he uses a protractor or chart plotter there are various sorts, like the Cras, the Breton, the Portland or the square protractor. But the heading on the chart true heading is not quite the heading to follow because you must take into account leeway or drift and the currents.

So the navigator does some variation calculations in function with the strength and direction of the currents to give the helmsman a "compass heading".

From this, the crew can estimate the time needed to complete the course depending on the point of sailing and the speed of the boat, and also depending on the strength of the wind and the state of the sea, in other words, the weather. PBO is a hi-tech fibrem which can carry incredible loads of many tons, yet weighs virtually nothing.

Traditionally racing yachts have used metal rod rigging to hold the masts in place and absorb the associated loads. Kevlar, Spectra, Vectran and PBO are all different materials that have been introduced in the past decade to reduce weight, improve reliability and make the boats go faster! PBO in particular is now also used in racing car applications in Formula 1 for the same reasons Pitstops — what is alllowed in the rules?

The boats may anchor or moor as close to land as they wish, but the skippers must not go ashore above the high water mark, and must receive no outside assistance, or physical contact with other people. Port tack - when wind is on the left side of the boat going upwind and indexsail is on right side of boat. To go in a direction against the wind, the boat must tack between port and starboard in a zig zag fashion.

Nach jeder Teilstrecke werden die Punkte wie folgt verteilt: Das ist nicht bei allen Veranstaltungen so: Einige Rennen laufen in Etappen - wie die Solitaire du Figaro. Der Sieg wird nach verstreichender Zeit gemessen - also, der Erste siegt und bekommt den Preis. REEFING The indexsail the large one supported by mast and boom can be 'reefed' to 5 different configurations, each one smaller than the previous. To 'put the first reef in' means to lower the indexsail to the first reinforced line in the sail.

At either end of the sail there are eyes and ropes that can be hauled in from the cockpit using winch and pedestal to 'reduce' the sail. When Ellen wants to increase sail again as the wind drops, she releases these lines and then must grind the sail up the mast again. Whilst the North 3DL sail onboard Kingfisher is ultra-light technology, it is still comparable to hauling up a large fridge - an exhausting exercise. During the EDS, each member of the crew has his own role. There are 5 people on board 2 English guys and 3 Australianswhich makes manoeuvring much easier and a much speedier affair altogether: The reason is principally due to the very wide shape of these boats, when they are heeling, if there was only one central rudder it would come out of the water a considerable distance and so control would be lost.

Secondly to help the autopilots, two rudders are used one on each side of the stern. When the boat is heeling the leeward rudder is completely in the water, and the windward rudder usually completely out — and reverses when you are the other tack. Therefore breaking one of these does not mean you have a second spare one, as you need both Most of the newest generation Open 60s have flip-up rudders. All Open 60s have two rudders due to their width the windward rudder is often out of the waterand the modern ones have configured them such that if they have a high speed collision a fuse breaks, the rudder comes up out of the water rather than being destroyed by the impact.

A broken rudder could be race-ending. Letztes Jahr am Juli, lancierte Olivier de Kersauson seinen Maxi-Trimaran: Sicherheit an Bord ist oberstes Gebot. Die Rennbestimmungen definieren die Sicherheit.

Weather Without any land masses to hinder them, the weather of the South is driven by a series of low pressure systems that circle the bottom of the globe around Antartica. The winds and wave heights can build to severe storms, and are particularly unstable.

The wind in the southern hemisphere rotates clockwise around the systems the inverse of the northern hemisphereso being on the northern side of them gives favourable downwind conditions as they travel east. However, the further south you go the shorter the distance you sail. Finding the compromise is the key decision to make Speed through the water Why are multihulls quicker than monohulls?

The answer is simple. Not having a keel, they are lighter and have a much lower wetted area than monohulls. So they suffer from less drag in the water and therefore go faster. In addition, their three hulls give them form stability that allows them to increase their sail area.

They are more powerful and capable of creating their own apparent wind for propelling themselves. In this way, the maximum speed of a 60 ft trimaran can reach 36 knots 67 kph whilst that of a 60 ft monohull tops out at 28 knots 52 kph. In 40 to 50 knots of wind in a big storm, like the leaders have been seeing recently, they are not going any faster. Large breaking waves are the really dangerous part. Trying to stay on deck and hand steer the boats is virtually impossible for anything other than a few minutes, as Nick in just 30 knots has described this morning With modern high performance sailing boats, the power to weight ratio is such that they are able to sail faster than the wind in many conditions — essentially they create so much apparent wind of their own see previous Jargon Buster!

Boats are becoming lighter and faster with each iteration of design and material advances. All these terms mean the same nightmare for the sailor: One can always resort to the "iron topsail" engine or one can break out the paddles.

But by a stroke of misfortune, if it happens during a race, the only option open is to be extremely patient and limit the damage as much as possible, like not going backwards for instance with the current. If the depth of water allows, one can allows anchor and wait for Aeolus the wind god to wake up. Contrary to popular belief, such a situation is not a good time to catch up on rest either; the noise of the sails beating back and forth and the creak of the boom swinging from side to side is generally most unpleasant and annoying.

You can't drop your guard either because the slightest zephyr could enable the yacht to make precious headway and escape from her competitors. The crew must permanently trim and re-trim the sails ready to capture the slightest tremor of air. This ensures lower speeds, therefore greater interest in terms of strategy.

Another important criterion is visibility and that the public should be able to understand what is going on.

West Winds

The starting point is usually in line with a landmark for example a lighthouse. If this is not possible, a mark at sea is used: Five to ten minutes before the starting gun a warning signal is displayed in the form of a flag. Then comes the preparatory signal code flag 'P'. The boats start to head for the line in order to cross it at full speed. Finally comes the starting signal itself. All the preceding flags are lowered, and a gun is fired.

Then lift out the old dagger board. It requires a lot of co-ordination, and good timing on the tacks.
