I have never been happy with the figurehead which appeared cartoonish. So I have gone back the original potterry images and found this excellent image of the tragana ship The figurehead I couldnt recognise until I suddenly realised that it was in fact a stylised crocodile head with projecting teeth.. I also have done some nose art using an image of a minoan octopus which was much copied by the mycenaeans The octopus would be an appropriate animal for a ship of Poseidon So the latest figurhead is much more threatening. The crocodile would be familiar to mycenaeans who regularly traded with Egypt. Cheeers Dick

Thanks, Mark.I believe the planking in a gun deck of a warship would be oak. As this was a merchantman, I would think elm or fir. The thickness of the central plankage was of the order of 90 - 100 mm and the outer planking 70 - 75 mm. Other members may be able to give much more detail on plankage. It is said that the old forests of europe never recovered from the stripping that occurred to make the war armadas of the 16th to 18th centuries. Cheers Dick

The thick planking has been applied as far as the midline, Dick

I have installed the waterways both sides. Cheers Dick

This vessel did not have lodging knees but lodging planking, this would save money. Knees are made from grown compass timber ( this grain follows the shape of the knee) and for a humble merchant vessel would be expensive overkill. Hanging knees however were used and presumably grown. Dick

Thanks for showing us Kroum's Video, Steven. Very useful for future builds. Let's hope more preserved wrecks are found and that nondestructive visualisation of buried parts of the hulls and rigs can be achieved with further advances in technology. Dick

This painting of the stern of Venezianos nave shows somewhat less substantial supports for the stern castle than yours but of course it doesnt project as much as yours either. Dick

I have installed the main deck beams and hanging knees as well as installing the bitts and all mast partners. The plan is to leave the deck largely onplanked so as to be able to see the lower cabins and the false deck. Dick

There is no doubt that loading ports on at least one side were used and are seen in a number of illustrations for example St Marks coffin being loaded through such a port. As Roger states, it would be ridiculous to set sail with a crenellated hull. I believe the artists sketched thes e ships in port so while loading. At sea the port would be covered to restore freeboard. I took this into account on my round ship reconstruction by building in removable panels which could be rapidly removed and replaced. I used Lillian Ray Martins book extensively as an excellent albeit fallible resource. Dick

I agree with Baker. That black could be toned down with a light buffing, Here are some bangladeshi boats to show effects of wear on pitch, Dick

The open area contained by the "brace" probably obviates the need for a hawse hole (not seen on the mosaic), do you think? There is a bitt here which would serve. The mosaic also suggests that the "brace" and the curved stempost is rabbeted. Does this suggest that at times this area might be planked in as an anti splash cover?🤔 Dick

To drill out the mortices you have to have a decent width of plank or you cant do it. Hence the large scale. This next is from my mycenaean build and I used a jig to do the mortices. But now I do them freehand. I can see why slaves were so prized in the ancient world. This type of repetitive, boring job would be given to them. Also the making of pegs.🥱 Cheers Dick

The keel is jarrah. The planking is a hardwood and I think its meranti. Here is the first attempt at mortice and tenon Pine tenons. I have fixed all planks with mortice amd tenonand will peg them later. Pegged mortice and tenon carvel planking had been in use in the Mediterranean since the Bronze Age (see jmy mycenaean war galley build).

A closeup of the keel section, showing the two keel rabbets. The outer rabbet is for the thinner sacrificial outer planking, The inner is for the thicker inner strakes. Dick

Bit unfair to non Aussies. We are referencing an obscure but iconic australian comedy movie called "The Castle". It's mostly about the Vibe. The next step is to carve the rabbet for the garboard strake. But the garboard is not a simple plank, it's a carved polygonal plank and is vital for producing the "wine-glass shape of the hellenistic merchantmen. image from sketchfab Dick

I have knocked up a mid hull mould to which the keel section will attached. This will also incorporate the mast-step eventually. Dick

I have received some more detailed drawings by kind courtesy of Dr Pierre Poveda . The drawings are extracted from M. Rival : La Charpenterie Navale Romaine The following are excavated sections of the vessels bottom Further detail of the keel showing the double planking and floors For an idea of what the ship lloked like, it is thought that this mosaic of a very similar merchantman from Themetra in Tunisia is as good as it gets, Cheers Dick

In this case I am standing on the shoulders of several decades of meticulous excavation and documentation by french archaeologists and aided by photogrammetric reconstructions to enable a credible idea of the hull shape.I claim no originality but am just doing a model in wood of what has already been done virtually.

There are many constructional peculiarities in this vessel which make it differ from later vessels. Having just had 3 weeks travelling I have had time to think. I have concluded that, in order to understand and demonstrate these peculiarities, it would be advantageous to construct a cross-sectional model. Otherwise it would just be another roman ship model. There is enough excellent excavation data to allow this. Dick

I should refer you to my recent build of a mycenaean galley (link below) built shell first and carvel as was the Uluburun ship. And this was in the Bronze Age! There is nothing new under the sun! Dick

The more deeply I delve into this , the tougher it gets. Not only was the original Roman vessel built shell-first but it was double planked externally. The framing was inserted after the completion of the shell. As to the hull shape, this has been a matter of academic spleen since it was excavated and remains controversial. Millenia on the sea bed with hundreds of amphorae pressing down have provided some interesting distortions I'm sure. Even so, below the turn of the bilge there was good preservation and the backbone is all there. So it seems that I should start with the quite complicated keel and stern post. Did the romans use any moulds to aid their planking, I dont know. Your guess is as good as mine. Cheers Dick
