The hull, the stern and rudder


The rear of the hull can have different forms depending on the material e t t ype construction.

On a wooden boat of conventional construction, the keel has ends at the back by the stern , more or less inclined, which is fixed on its f ran rudder. This one is connected to the bar by wick that crosses the arch and the bridge by a tube, sealing: the rudder stock . (See below)
The bor dice can go back n e rising below the waterline: the vault may continue until pavo is or end with a more or less inclined.

Above the old tuna Biche awaiting restoration (February 2008) shows that arch that extends through a highly sloped transom . The set is quite fragile, and in this case, very tired.

much more recent and in excellent condition, Grand Léjon to the stranding, shows an elongated arch and a transom and a little less inclined to lie entirely above the deck, light green is the bulwark, the dark green the topsides located below the deck and the hull is painted black.

The transom may be bigger and begin to understand the waterline or even below: one speaks of transom stern. Saffron revolves e then both the stern and on the table. the bar can pass through a hole in p avo IS, close to the bridge, as in the photo below, or it passes over the table to.

A beaching, Saint-Quay shows a good example of this type of rear table starts well below the waterline , the edges that are not in follow those of the hull and there is no vault between the stern and transom.

This background has become widespread on medium sized boats after World War II, along with the propulsion motor and propeller replaced the sails.

The back of this old fishing boat, which turns gradually into wreckage on the edge Trieux, is representative of this period (between 1945 and 1960), with its flat and almost vertical array.

The top of the table is sometimes perforated:

We see an example above with Agnes ; such transom boats often characterizes Pilot ( Agnes cutter is a replica of Scilly Islands)

The yachts have généralemen ta ar career to vault it is very thin and elongated on classic yachts. depending on the case, it does ermine or not by a transom, often when there is too sloped.

Marigold, above, shows an example of the very back ends that help to give a look so sleek hulls of these boats to .

Many yachts, mostly from the years 1970, tables back inverted (turned up).

The 12 m JI Challenge 12, above, shows an example of reverse transom, almost horizontal in the extension of the bridge.

There may also be pointed back to , resemblances t a bow:

This image of Cherbourg longship Dreknor shows that the back is different little front . Seen from afar, they differ just by the decor (the stem is adorned with the dragon's head, the back of his tail).

until the Middle Ages, for example on Viking ships, this sharp back s not wearing a rudder the boat was headed by an oar short and wide, placed on one side of the hull ( usually to starboard).

In this photo Dreknor , seen backwards, we see the top of the rudder (to starboard, ie to the left of the picture). The train is over a sculpture representing a human head, while the bar is facing the inside of the boat.

This picture shows the back of sharp Dreknor side and rudder, which is maintained along the edge with a piece of wood and a leather collar somewhat hidden by the hawser) and is based on a reinforcement of the hull, shield-shaped.

This detail of the previous picture shows the rudder, sculpture who ends up and how the bar hinges on the train. This type of rudder is easily met for navigation rowing in shallow water.

The rear can be pointed almost vertically and construction included an end stern, which can carry a rudder: it speaks of back canoe, or Norwegian.

Coronasia , constructed a map of the Norwegian architect Colin Archer, shows a typical example of these back in Norway.

There is also a pointed stern with stern rudder on many boats Southern Brittany on mushers ups sailboats and some Mediterranean canoes sailing and rowing.

Our Lady of Bequerel replica of the rover Bono (small river port of Auray, in Morbihan) , is an example of a rather special boat south of Brittany.

San Antone in the back typical Mediterranean sharp.

Tall ships have a former ar career very elevated, dominated by the castle where are the housing officers. From 16 th to 18th century, these castles were richly decorated back and added to the nav much ires.
Examples:

Endeavour (late 18th century)

Amsterdam (mid-18th century) .

Shtandart (early 18th century) .

Batavia (17th century).

Prinz Willim (17 th century).


The Matthew (late 15 th century).

On Tall Ships Commercial 19th century and 20th century, and the sailing school , there is no castle so high, but a poop overlooking the bridge. this poop is an additional bridge, she wears the helm, and often a deckhouse contained the chart table and and instruments used for navigation. Under the poop are the homes of officers and, often, a luxurious reception room (especially in training vessels). The hull of the barque Christian Radich includes poop in the back and a fellow front, between these two ends raised for the remainder of the bridge called safe.

Boats metal have practical cally always has a rrière vault, perf ois supplemented by a table.

Above the rear of the Russian tall ship Kruzenshtern . under 2 different angles, making conspicuous the vault, and the provision of saffron and its wick.

The transom Pogoria is reversed, and the vault is completely submerged.

The back of a boat wears his name and port ; on many Dutch ships, only the port is specified, which can cause confusion, the name is then placed on each side of the bow.
The back of some boats can be decorated, even when there is no imposing castle back.
The rear of the Norwegian barque Statsraad Lehmkuhl, whose home port is Bergen.

The rear of the schooner Brest The Recouvrance .

The rudder classic includes a rudder, hinged on the stern or on the tab Leau pintles rear by passing through gudgeons or suspended a lock, and a bar . The wick, when the rudder is suspended through the hull in a sealed tube: the rudder stock (or tube rudder stock) , we see these elements on the photo The Recouvrance above.

The photo above shows the back of the schooner Oosterschelde . The rudder of the ship visible at the bottom of the picture, is connected to the wheel by the roving black stem) that is seen entering the rudder stock. Also notice the plates riveted on the original ship built in 1918.

The bar can be frank and articulate are directly or indirectly nt on the rudder when it is at the transom (on small boats), and if the SAFR year is suspended, the tiller is attached to the upper end of the wick that crosses the bridge. From a certain size of boat and a certain wind strength, the tiller can not be handled directly by force of arms, muscled same: we must act through hoists moored each side of the boat.


Above we see the provision of high tiller cutter Sainte-Jeanne , its articulation on the end of the wick and hoists that, on each side, help her maneuver when the wind freshened.

On vessels of a certain size, the bar is a wheel whose axis is connected to the rudder by a set of pulleys and cables or chains, drosses .

system steering wheel of Bounty is one of the simplest of all: the reefing line is a rope wound around a drum and liaising with saffron through pulleys.

The mechanism is often more complex and sheltered by a small deckhouse called turtle. On the schooner Eye of the Wind, you can see the turtle painted wood, behind the bar roue.On Other examples of tortoises in the chapter devoted to decks and deck houses.

This photo shows the tortoise Belem open: the worm, driven by the wheel acts on the rudder.


On larger boats in heavy weather, the boat must be helmed by several helmsmen (name given to coxswains on larger boats). The 3 steering wheels you see above are available on the three-masted Sagres, to the chart room, visible in the background. They are connected to the rudder by a transmission rather complex.
Another wheel is behind the deckhouse and acts directly on the mechanism contained in the turtle.

When there is a steering wheel, at least on small and medium sized vessels, a system can use a tiller if problems arise in the transmission mechanism.

The steering wheel can, on most tall ships, including school, be disconnected from the rudder, the commander then uses an electric drive , faster and more accurately, to steer the ship maneuvers at ports and passages in the channels difficult. The steering wheel is returned to service at sea

We see in this picture the commander of Belem, his second and the pilot (right) upon entry in port.Ils are mounted on the roof of the room provided for a better visibility on the front, the first mate (middle) holds in his hand the remote control of the bar.

On many boats of average size or larger racing yachts, is a system of autopilot, which just set a course and it is often better than a bar means when the boat helmsman ship Wed released.
