SYRACOUSIA VI : DON'T GIVE UP THE SHIP!


DEFENDING THE SHIP

 There were also eight turrets on it, of a size proportional to the weight of the ship; two at the stern, an equal number at the bow, and the rest amidships. 
To each of these two cranes were made fast, and over them portholes were built, through which stones could be hurled at an enemy sailing underneath. 
Upon each of the turrets were mounted four sturdy men in full armour, and two archers. The whole interior of the turrets was full of Saracen and missiles. 


TURRETS

These turrets have been interpreted as full height towers. This is not necessary. The meaning is a fighting platform. They were not massive - they housed just 4 men and their ammunition. 4 metres square would give ample fighting space plus some racks for amunition.
 
Ship tower a la Ben Hur. Nice, but practical?

A light wall around them would deflect missiles and they could be furnished with machiolation. Sculptures suggest they could be painted to resemble stone-built structure but this is not definite at this early date.

Maybe more like this..fighting platforms not Rapunzel towers
 The 'Saracen'  mentioned here is, I believe, tow-like fibre which can be easily lit. Presumably for making fire missiles.

STONE-DROPPING CRANES

The crane weapons are interesting. They are designed to prevent smaller craft coming alongside - as pirates are wont to do.


The ammunition must be lifted by 2 men by hand so we must assume the calibre was around 1 or 2 talents  25 or 50 pounds, 12 or 25 kilos.(approx.)

Such stones falling 10 metres would have considerable force to crush men or spring planks in a small hull.


The weapon is interesting because it has some parallel with the Theban 'flamethrower' used at the siege of  Delium in  424BC. This was also made of 'beams' hollowed.

There was plenty of ammunition supplied and it would be a brave attacker who came alongside Syrakousia.


MAST-CRANES AND DOLPHINS

 and as there were three masts, from each of them were suspended two large yards bearing stones, from which hooks and leaden weights were let down upon any enemy which might attack the vessel.

Each mast had men serving lines and pulleys which controlled extra yardarms - cranes - which allowed dolphins to be suspended out beyond the ship's sides. Dolphins were an old weapon, used,  not for the first time, at Syracuse in the Peloponnesian Wars.

The principle was similar to the turret cranes, in that a targetted vessel would suffer a heavy weight smashing vertically down into it in free fall. Dolphins could be random heavy things but, in the absence of grand pianos and ton weights the ancients used torpedo or dolphin-shaped lead castings.


ACME is a Greek word, you know? Doesn't lessen the pain though..
 The dolphin was raised to the top of the yard, the yard steered round to hang over the target - probably aimed using a hanging plumb bob - and then released by pulling a pin or slipping a line. Maybe the dolphin could be hauled up for another shot, otherwise it would be cut away and another hoisted.


The same yard crane could deploy an iron hand / grapnel to catch a target and capsize it or hold it for others to attack at will.


 FIGHTING DECK - AN EXTRA DECK OR 1 OF THE 3 ?

A wall with battlements and decks athwart the ship was built on supports;

 Here we read that there was also kind of combat deck on the ship.

This is added to the 3 decks already mentioned. But as we shall see was not a complete deck.

A question arises as to if this was intended to refer to an extra superimposed structure or a specific part of the uppermost deck.

It seems to be an overlying structure because ..

a) the structures on deck 3 needed roofs and this platform could form their roofs.
b) the structure is described as being supported on trestles/tripods  (rather than the columns/pillars of this translation)

The description of a 'wall' crossing the ship is confusing...maybe it refers to the  fore and aft aspects presenting wall-like balustrades? Difficult to interpret.

The platform - which we can call Deck 3A - cannot have extended over the whole of the area of deck 3 because this would cover the promenades, gardens and gymnasium areas which Moschion was so keen to describe.

Deck fighters at this height on the ship  could only hurl missiles or wait to rush to places where attackers had breached the all-round barrior of  iron railings.

Attackers would not need to climb to the top deck. If they got aboard they would be distracted prior to that by the prospect of plundering cabins cargo and passengers while the deck fighters could be left to stew in the sun.
'Chaps, chaps.. I say..there are some steps just over here....

Each mast base needed an area for the mast and tops to be serviced. The large catapult needed a base to operate on and probably to be moved and trained in different directions.

The stables needed roofing. As did the library and reading room - though the roof of this had a circular hole for a sundial. Areas covered by the towers - 8 of them - would not necessarily need a fighting deck at those locations.

The solution would appear to be that there were katastroma-like  strips of decking located at crucial areas over the hull area. Early galleys were not fully decked, they had a narrow gangway down the mid-line connecting forecastle and poop. It is something like this we could see as Deck 3A on Syrakousia.
early undecked pentekonter, later eikosoros with through-gangway

schematic of fighting platform over Syrakousia's top deck
This is a difficult aspect of the reconstruction but we can be sure it was not a true extra deck.

Archimedes' Catapult
on this stood a stone-hurler, which could shoot by its own power a stone weighing one hundred and eighty pounds or a javelin eighteen feet long  This engine was constructed by Archimedes. Either one of these missiles could be hurled six hundred feet.

..this I will save for next time... plenty to deal with besides this....


After this came leather curtains joined together, suspended to thick beams by means of bronze chains. 

Such screens were a common device to block incoming missiles. They were bronze and heavy leather to avoid damage and absorb the energy of the  missiles. They are mentioned in the surviving treatises on siegecarft and artillery but we do not know exactly how they were made. A flexible and heavy hanging mat would catch flying missiles and absorb their force without itself suffering too much.


If you know what I mean....


An iron paling which encircled the ship also protected it against any who attempted to climb aboard; 

I have searched for surviving iron railings from the period or even Roman times without success. Iron is, alas, too -easily recycled for such mundane items to survive the centuries. One might be put in mind of the abbatis-like cervi of Caesar's circumvallation of Alesia whenh considering how these pailings functioned.


Railings could even be put into offensive action if one is so minded. Kubrick shows us how in his spectacle 'Spartacus'.
Some great railing action with Kirk HERE


also grappling-cranes of iron were all about the ship, which, operated by machinery, could lay hold of the enemy's hulls and bring them alongside where they would be exposed to blows.

These smaller versions of the mast-cranes or perhaps even catapult propelled grapnels made it dangerous for small vessels to approach Syrakousia. I have discussed the harpax, which is otherwise assumed to have been devised by Agrippa, Octavian's admiral, centuries later, in a previous post HERE


Sixty sturdy men in full armour mounted guard on each side of the ship, and a number equal to these manned the masts and stone-hurlers. 

This means there were 120 armed deck fighters manning the ship. There were cabins for them somewhere or else they must have sheltered under awnings on the deck or fighting platforms. It is interesting what the passengers made of 120 plus warriors milling around the place.

Jenkins rued the ticket price for his week on the Zambezi river considering the limited privacy the vessel afforded

Also at the masts, on the mast-heads (which were of bronze), men were posted, three on the foremast, two in the maintop and one on the mizzenmast; these were kept supplied by the slaves with stones and missiles carried aloft in wicker baskets to the crow's-nests by means of pulleys.

Syrakousia's 'fighting tops' were not the large, heavily-manned platforms of the 'age of sail'.



But they surely could deal some damage as the men up there were relatively immune from attack and well-supplied with missiles which would have serious effect when thrown from such a lofty perch.


Sluys 1340. Gravity still a potential threat.

DEFENSIVE STRATEGY

Syrakousia seems to have been designed with the idea of primarily keeping attackers at a distance. It would have been extremely dangerous for smaller craft, less than a trieres in size, to approach Syrakousia. This is consistent with the main threat being piractes rather than warships. Pirates operated with vessels that could be used as fishing boats when the owners cupboards were not bare enough to have their wives place a cutlass or grapnel on the dining table one evening.

Small vessels with clusters of desperate men aboard,  appearing form behind headlands were the pirate's mode of attack. Several vessels could cooperate to corner a victim. The denouement was when a wave of badly dressed expert sailors swarmed onto the cornered vessel and waved very sharp agricultural instrument under the noses of the occupants who had not already had a siezure or jumped overboard.
Who is tractoring who ?

To be taken by pirates meant certain slavery, possible ransoming, rape of all denominations and death or mutilation for the uncooperative or unlucky. Not to mention the loss of the cargo and the ship. Hence defence.


Along each side there were 7 crane weapons which could reach out several metres. There were the tractor beams . the grapnel thrower - which could drag unwary attackers close.




There were 60 deck fighters chucking javelins, stones and shooting arrows on each side.

 
Cruel, yet satisfying.

 If the attackers got alongside they had to climb a spiked iron railing under shot and spear-thrust.




Once aboard, the crew of 600 ( ! ? ) would resist. Added-to the occasional sharpened hairpin or aggressive lapdog of the first class passengers this is a lot of manpower.



  

 
10 or 20 cutthroats would steer clear of Syrakousia. Several boat-loads of pirates would not bother with Syrakousia. It would take a major combined effort  of several settlements or a state-backed episode of privateering to think about tackling Syrakousia! Unfortunately such shady enterprises were usual along the rugged coasts of the Mediterranean. Hence, Syrakousia was such a bonney girl.
Beautiful lines, full form, comfortable ride, but sharp talons and expensive to maintain : Pirate keep your distance!!!

 Had they but world enough and time no doubt Hieron's brains trust could have devised anything. The only way to secure her cargo better would have been to make Syrakousia a U-boat. Looking at the early models such as Turtle and the Holland, and considering Aristotle's observations about snorkels or breathing lines.....


Just then as divers are sometimes provided with instruments for respiration, through which they can  draw air from above thewater, and thus may remain for a long time under the sea,so  also elephants have been furnished with their lenghened nose wherever they have to traverse the water they lift its tip up above the surface and breathe through it. For the elephant's proboscis as already said, is a nose. 
(Aristotle, de partibus animalium, Part ii.16:658b30 f.)

Probably it was the plans for a u-boat which a Roman soldier stood on as he butchered Archimedes.
Alexander is reputed to have gone down in a diving bell, maybe even with Aristotle, at Tyre. Sadly,  this story has no historical foundation. 
But Syrakousia proves, truth is usually stranger than fiction....

RAMMING IS NEVER OUT OF FASHION

On 30 March last, a Venezuelan navy patrol ship - 80m Naiguata -

 
 
has tried to divert a cruise ship.. RCGS Resolute off its course. By nudging it round at the bow....



This took place off the north coast of Venezuela near  La Tortuga.  Some kind of misunderstanding..

Unfortunately Resolute has a hull reinforced for polar ice-breaking trips and an ice-breaker bulbous bow....concealed under the waterline.
 
 Lightly built navy ships tend to come off second best against tough hulls as the British navy found during the Cod War ...

Naiguata sank but all hands were saved according to the Venezuelans.

It is incredible behaviour for a navy ship. It is incredible that the Venezuelans had not even looked up their target on the web..as anyone can do .. and seen it was a tough cookie.

This blog approves of the way in which the Venezuelans sought to continue the age old tradition of ramming combat but disavows attacking civilian ships or use of kamikaze tactics.

SYRAKOUSIA V : THE AMAZING TOP DECK

DECK 3 - THE FLOATING GARDENS OF HEIRON

The top deck as described by Athenaeus-Moschion was a truly amazing conglomeration of facilities that sounds more like a small town than a ship. Here we begin to imagine parallels with the barges of Caligula and the Ptolematic thalamegoi.

Here is the text .. it is difficult to translate and cannot be said to make complete sense.

On the level of the uppermost gangway there were a gymnasium and promenades built on a scale proportionate to the size of the ship; 
in these were garden-beds of every sort, luxuriant with plants of marvellous growth, and watered by lead tiles hidden from sight; then there were bowers of white ivy and grape-vines, the roots of which got their nourishment in casks filled with earth, and receiving the same irrigation as the garden-beds. These bowers shaded the promenades. 
Built next to these was a shrine of Aphrodite large enough to contain three couches, with a floor made of agate and other stones, the most beautiful kinds found in the island; it had walls and ceiling of Cyprus-wood, and doors of ivory and fragrant cedar; it was also most lavishly furnished with paintings and statues and drinking-vessels of every shape. 
"Adjoining the Aphrodite room was a library large enough for five couches, the walls and doors of which were made of boxwood; it contained a collection of books, and on the ceiling was a concave dial  made in imitation of the sun-dial on Achradina.  
There was also a bathroom, of three-couch size, with three bronze tubs and a wash-stand of variegated Tauromenian marble, having a capacity of fifty gallons. 
There were also several rooms built for the marines and those who manned the pumps. 
But beside these there were ten stalls for horses on each side of the ship; and next them was the storage-place for the horses' food, and the belongings of the riders and their slaves.  
There was also a water-tank at the bow, which was kept covered and had a capacity of twenty thousand gallons; it was constructed of planks, caulked with pitch and covered with tarpaulins. 
By its side was built a fish-tank enclosed with lead and planks; this was filled with sea-water, and many fish were kept in it.

Let's take Makintosh et al's plan of Deck 3 as a starting point.


Here they opted for central walkways and keeping the different facilities separate. This is not necessary nor logical.

If we continue with the basic principle of keeping weight central and the gangways peripheral we find a simple layout almost draws itself.

We should bear in mind that gangways need sloped sections communicating with the lower levels.


AGGLOMERATED STRUCTURES

I cannot see how  a ship would be built with disparate structures separated on a deck. It makes more sense to build them together to add stiffness to the structure and save on shared walls. Likewise they should be central as possible.


The temple is rather small - equivalent to a 4-couch cabin in all, maybe.
Likewise, there is no reason for the library and reading room to be of any great size.

This leaves us with the gymnasium and baths.

The gymnasium would be an open area with collonaded surrounds, Exercise would be conducted in the central area of sand or grass and the shade used to relax or prepare.

a  full-size gymnasium had many ancilliary rooms to the exercise area. The quad here is 50m square.

teaching and exercise took place in the open or under cover
 The gymnasium on the ship was probably mostly for exercise. We can forget all the extra rooms and think of a collonade around an open area.

 The baths need not be so large. we are not talking of a Roman bath complex , rather a more simple affair. Greek baths had short bath tubs maybe some massage area.

bathtubs of ceramic or metal or stone - one sat on the step
Greek bath complex at Gela - several dont take up much space

 A 3-couch room with 3 bronze tubs could again be equated with a 4 couch cabin.


The library was 5-couch size - scaling up a 4-couch cabin we have something like 4 by 4 metres. It had a complementary reading room of the same size. The two seem to have shared the same roof which was pierced with a circular hole to allow a sundial to stand . The usefulness of a sundial on a ship is dificult to explain, unless there was no plan it should go anywhere... 

The presence of the stables here is very informative. Horse need to be led up onto the top deck. Stairs dont go well with hooves. There must have been ramps. Unless the horses were put aboard by cranes. Unlikely, I imagine. How would they be disembarked in a pinch?

PEOPLE-CARRIER OR HIPPOGOGOS ?

Makintosh et al make no provision for stairwells or ramps on either deck. How did they imagine people and horses moved between decks?

Peripheral paradoi can have ramped sections or even be accessed by a sloped gangplank from the dock.

There is some possibility of having more than 10 horses on each side. Did each stall or stable house more than 1 horse? We can never know. Makintosh et al decided that there were 100 horse because they drew parallels with a medieval salandria used for carrying horses to Outremer. But such a scale is not necessary - and the dung and urine and flatulence of 100 horses does not marry well with pleasure gardens, temples and library reading roomse etc..

A Roman barrack for  cavalry housed 3 horses in about 12 square metres, 3.6m square,  and the troopers and their gear in an equivalent space alongside. This tallies remarkably well with the 4-couch cabin , note.
Reconstruction of the ‘stable-barracks’ at Chesters Roman Fort © English Heritage (drawing by John Ronayne)
Reconstruction of the ‘stable-barracks’ at Chesters Roman Fort © English Heritage (drawing by John Ronayne)
A small cavalry unit of 20 men is still useful - or the stables could have been for racing horses or even pack horses !?

If there were 100 horses we must assume there were 100 riders and probably 100 grooms. Plus fodder and gear.

If we have 'Roman size' stalls with 30 horse per side then 60 is still a lot but a lot less than 100!
There is no fundamental reason to require the ship to carry 100 horses.

with Roman barrack size accommodation horses com eto dominate the purpose of the top deck. Can this be true?
The ship was not a horse transporter. 20 horse would be enough for commercial transport or protection of the ship if stranded on a coast.

If we take 1/3 size of the Roman stables maybe that is plenty for our purposes.

The horses must have been closed-in for the duration of the trip and led up ramps for embarkation.

All these structures were roofed to some extent and must have been built to share supporting walls.

The Athenian used old trieres as hippogogoi in the Peloponnesian Wars. The horses were in stalls on the main deck and 30 could be housed in the 38 metres length of a trieres.
from Coates - Athenian Trireme. 1st ed.
But there was no extra gear no grooms etc on this type of transporter which would never stay at sea overnight.

Horses COULD be crammed in to Syrakousia. The question is why would they be ?
To put a hundred horse on a deck upon which so much effort had been spent to make it luxurious seems somehwat perverse. The only way I can imagine the two coul dbe combined is to put the stables at one end and the facilities at the other. Even then, the reality of the pleasure gardens would have been somewhat negatively fragrant. But maybe that was why the flowers and bushes were needed ?  ;)

Makintosh et al offered a possible solution..They calculated that 20 horses would occupy 34 square feet. I am not sure what  kind of horse they meant, but even a pony would be hard put to suffer transportation in a trailer-box of just 1.7 square feet. Did you see 'bonsai kittens' ?

Dwarven cavalry as envisaged by METRO.co.uk : still somewhat squished in 1.7 square feet

GARDENS ETC
All the remaining spaces were decked-out as gardens and promenades, watered by a system of pipes. Overhead bowers and palisanders gave shade for the promenders.

Roman garden...


The need for light for the greenery and the function of the greenery as a shade means that Deck 3 was not covered with another structure.
Roman gardens with espaliers and arbor walks.
See also earlier post HERE

THE WATER TANKS

The quantity of water is 20,000 gallons of drinking water plus the aquarium for food fish. A tank for this takes up just 8 by 5 metres if it is 2 metres deep. Maybe the aquarium is smaller.  either way it is not a great space. The tank is supposed to have been in the bows  but it is more sensible to put such a tank close to the centre of gravity of the ship so that it does not begin to move dangerously as the ship pitches. The translation might be off or the amount of water less than we think. But it is also to be remembered that this ship was an exception. An experiment. The tank was closed, so this may have been an attempt to counter movement of the water causing problems.


SUMMARY

Deck 3 was mostly open. It was a pleasure garden type space with greenery and shade against the Mediterranean sun as well as space to walk and exercise. Maybe all structures actually butted up against each other.
Maybe the stables coul dbe at fron tor back, but there is a reason to put them at the centre..see next part.. the horse dung and urine is still somehwat problematic, even for 10 horses. It must have gone over the side.
This open deck would allow for movement of deck fighters and defence of the ship from this level. But there were also extra arrangements for the defence of the Syrakousia. As we shall see.

SYRAKOUSIA IV

Now we have to work out how to reconstruct the topsides for the Syrakousia.


Just a simple matter of putting the top bits on...

Now it is necessary to refer back to Athenaeus for what he says about Syrakousia.

 ' with three gangways. the lowest gangway which it contained led to cargo, the descent to which was afforded by companion-ways of solid construction; the second was designed for the use of those who wished to enter the cabins; after this came the third and last, which was for men posted under arms. .'

 ' On both sides of the ship were projecting beams, at proper intervals apart; on these were constructed receptacles for wood, ovens, kitchens, handmills, and several other utensils. Outside, a row of colossi, nine feet high, ran round the ship; these supported the upper weight and the triglyph, all standing at proper intervals apart.

' A wall with battlements and decks athwart the ship was built on supports; on this stood a stone-hurler, which could shoot by its own power a stone weighing one hundred and eighty pounds or a javelin eighteen feet long. 

Á lot to take in ..and there is more we will consider later.

The first part to look at is the RED text about projecting beams. These would be thwarts set across the topwale of the main hull. This had been launched after it was sheathed in lead to protect it against ship worm. These thwarts would support the main deck. This level was above normal wave height and we might imagine it  a metre or so above the waterline.

These beam ends could project out a metre or so. On these beams were booths and huts for the various ancilliary functions of baking, and food preparation and storage of gear. There is no need to imagine that these lockers ran the whole length of the ship.

Also standing on these beams were 'kolossoi' - male statues in conservative poses - These were like caryatids, they had a structural function as pillars or columns. They were 6 cubits high or 3 metres.
This gives a height for the next deck over the main deck - maybe. All around the main deck were these male statues - painted wood, one presumes. They must have stood higher than the booths  or lockers we mentioned before, or they stood outside of them.


karyatids on the Erectheum at Athens. The male version resembled Rhodes' famous statue to Helios maybe.

The kolossoi supported 'the triglyph'. This is part of the entablature of a classical temple.  This must have been a detail around the overlying deck edge. Only the Doric order has a triglyph so we must assume other ornament would be as severe and simple as to fit with this style.

Triglyph with metopes - gaps between - Kolossoi would replace the column here shown

 HOW MANY DECKS? - A VERTICAL CROSS-SECTION

Athenaeus (or Moschion) tells us (BLUE text above) there were three gangways, one above the other.
If we take one to be at the level of the main deck then there were two above that one.

The word used is parados - which, on a warship, meant a walkway on the exterior of the ship, later, sometimes formed by the top of an oarbox The parados in a Greek theatre is a side entrance where the chorus can walk out in front of the stage. Again the meaning is that it is open to the view.

Some translations interpret these as entrances or access gangways but this makes no sense if they are side by side when the meaning is obviously that they are above one and other.

So we seem to have a series of verandah-like open-sided decks with rooms/cabins inboard. We must assume a balustrade surrounded the whole to avoid too many man-overboard incidents!

If the gangways/paradosoi are on the outside this adds to the ship's stability because the mass of the cabins is nearer to the centre line.

The hold was reached by 'companionways' or ramps leading down into it from the main deck.

Access between levels must have been achieved by similar sloping ways between the overlying decks, Cargo and passengers cannot have been expected to negotiate ladders adequate for sailors and deck fighters.


The lockers/booths on deck 1 could be inside the supports but I suspect they should be between them and not necessarily all the way around the ship. 'Outside' means the kolossoi were on the exterior of the superstructure. I think.

This arrangement differs somewhat from that proposed by the most recent reconstruction by Makintosh et al.


Makintosh et al have no main deck - no deck which is secured on the thwarts and topwale of the hull construction before the superstructure is constructed upon it. But they did not construct a vertical cross-section to allow us to see exactly how they configured the decks.


DECK PLANS - HORIZONTAL SECTIONS

The deck we have most information about is the third one, with its stables etc. But we have no information as to how the different facilities were laid out.

The second - middle - deck has a large state room and 30 smaller cabins.

The upper deck has a temple, stables etc !!! How could they be laid out ?

Makintosh et al made a basic guess without going too much into details..
CABINS SPLIT TO BOTH SIDES, STATEROOM PUT IN CENTRE ( no galley for state suite ? )

 DECK 2

After Moschion's account, Athenaeus writes ....

  Belonging to the middle gangway were cabins for men ranged on each side of the ship, large enough for four couches, and numbering thirty. The officers' cabin could hold fifteen couches and contained three apartments of the size of three couches; that toward the stern was the cooks' galley. All these rooms had a tessellated flooring made of a variety of stones, in the pattern of which was wonderfully wrought the entire story of the Iliad; also in the furniture, the ceiling, and the doors all  these themes were artfully represented.

The gangways I already decided were on the outside.
The cabins divided in two rows, back to back, with doors to the outside gangways, formed the main area and then, to the stern was the larger cabin with its smaller ancilliary rooms, including the kitchen.

The couches spoken of were couches on which one reclined to eat or sleep. Their size can be found in other ancient sources and by supposition.
A couch should be at least 2 metres long and 1 wide, say. Makintosh et al used a size of 6 x 2.5 feet. - 180 by 75cm. A crucial thing might be to include some space to move around in the cabin - which Makintosh et al did not do....jokes about modern shoebox houses aside.. this is surely wrong.

cat swinging somewhat restricted in second class

We must allow at least the same space as a couch to allow people to actually move around the cabin.
Notwithstanding they also got the calculation wrong - using 4x6x2.5 as 102 square feet rather than 60, for example, a cabin with 4 couches 1.8 by .75 metres plus an equivalent amount of floorspace comes out at 10.8 square metres. (116.25 square feet).

The couches referred to here are the bed-like furnitures used for eating in a reclined posture - and for sleeping on at a pinch.


 A room could be decsribed as having space for x couches. even if there was no standard couch size the approximation was useful for comparisons.


A cabin with couches arranged like this would have space under the couches for gear and a central table plus space to moave around.

Our ypothetical cabin with additional floorspace alongside each couch equal to its area

1,8 x ,75 =  2.7 square metres per couch

Ancient examples give larger figures for palatial dining rooms...

At Vergina, the Macedonian Royal Palace,  7 couches per 25 square metres = 3.6 square metres per couch +/-

At  Perachora, Corinthia, 11 couches per 40 square metres = 3.6 square metres per couch

 A four-couch cabin on Syrakousia could look like this...

14.4 square metres : cabin side 3.8 metres

Let's take 3 square metres per couch....this means 12 square metres which is a nice approximation of a 3m square for each cabin's footprint. (square root of 12 is 3.4 - allows for walls )


Our overall deck area is 64 metres length minus 1/7 for bow and 1/7 for stern by 16 metres wide.
 9 metres at each end is lost as bow-stern areas, for now.
 64 - 18 (x 16) gives us 736 square metres  minus a 9 metre bow and stern section.

30 cabins this size(12 sq m)  use up 360 square metres. We have to add the stateroom so maybe our size estimates should be pared down, but we are in the right ball-park.


The parados around the deck - could be now 5 metres on each side ...lots of spare room to play with.

So let us relax constraints on the cabins to make them 4 metres wide by 3 metres . More room to swing the proverbial cats in now. Leaving 2metre exterior gangways on each side..

DECK CONFIGURATIONS : A) CABINS,B)  ADDING STATE ROOM, C) FINAL VERSION

Now for the state suite. Captain's cabins?

This is a biggy with 15 couch space and 3 cubicles of 1 couch size - or of each 3 couch size...depending on translation.

This is 15 x 2.5 square metres plus 3 cubicles of (3 x 2.5) sqm. 37.5 plus 22.5 = 60 sqm c. 8m square

W can shove the 4-couch cabins along a bit and still have space for the state-rooms AND the galley on the end.....

 - Makintosh et al  place the stateroom in the centre line of the deck . If it is square this is about 8 metres wide . Add 2 gangways at 1.5 metres and two 4-couch cabins as per their diagram - this is 3.5m width each -this is 10 metresof width, we have 18 metres of deck width. Somehwat exceeding their calculated width of 50 feet or 15 metres. They also go in for ball-park-ism.


To this we must add a kitchen at the rear - galleys seem to have usually been located aft in ancient freighters. In size terms it could be reckoned at another 4-couch cabin maybe.


Makintosh et al calculated Deck 2 as extending to 720 square metres (just 700 metres in another place..quite confusing) ......with the facilities taking up 461 square metres.

If we want to add the foreship and aftship areas we can count them as simple triangles and consider half of these parts of the simple rectangle available ..

This extends our deck square metres available by 219.

There is ample space for a gangway if we squish the cabins out to the ends of deck 3 and slim them down a smidgin...

64 x 2 x 1.5 = 196 square metres needed for gangways/paradosoi

SEE C) ON FIGURE ABOVE

 The height of the overhead on this deck does not have to be the 3 metres - 6 cubits given for Deck 1 which was surrounded by the kolossoi. We could redcue overheads to 2 metres - or 2.5 with no great problem. Thus saving on top weight.


In summary : our deck arrangements have been worked out to be economical with space.
The basic principle is to imagine the ancient ship as more of a Nile steamer than a modern cruiser with internal gangways.


Syrakousia was not so much this........


..but this.....

M.V. Sudan is 72 metres long. Not so different from Syrakousia.  She is slimmer than Syrakousia - only 10 metres in the beam. She has 23 cabins, 5 are large state suites. I would suggest that this is the more accurate impression of what Syrakousia looked like rather than HMS Victory or Noah's ark.
