  1. Having largely finished my build of the 13th century Round ship, I am going back in time to the 9th century. At this time a transition was in play in the Mediterranean away from the shell construction using edge joined planks with pegged mortices to what would become the skeleton type of construction using full active frames. The vessel I wish to construct was positioned in between these techniques in that it had a mixture of shell and skeleton construction used in its construction. In addition , instead of using mortice and tenon technique to edge join the planks, it used an edge dowelling technique. I will utilise the description and reconstruction published by the author: Işıl Özsait-Kocabaş Istanbul University, Department of Conservation of Marine Archaeological Objects, Ordu Cad. Laleli, Fatih, ˙Istanbul, Turkey The International Journal of Nautical Archaeology (2018) 47.2: 357–390 Copyright for images from this publication resides with Istanbul University Yenikapı Shipwrecks Project, I will withold these. I hope to be able to demonstrate the techniques used by the original builder. The dimensions of the vessel are length overall (LOA) 9.24m, beam of 2.64m, and depth of 1.10m. The length-to-beam ratio of the vessel is 3.5:1. The wreck was found in 2007 at the site of the byzantine Theodosian harbour, one of the greatest treasure-troves of nautical archaeology yet discovered. The wreck of YP12 has good preservation of keel, framing and planking sufficient to do a viable reconstruction. The keel is rockered, that is slightly curved, and made from three pieces joined by keyhole scarfs The stempost and sternpost did not survive and have been reconstructed. I have temporarily installed the spine of the vessels on posts as I believe the original builder would have done. This may end up becoming the stand of the model. Cheers Dick
  2. Having completed the venetian carrack or cocha, I now plan to reconstruct a merchant vessel that predated it and lasted into the 15th century. I have based the reconstruction on the measurements given for a nave latina in Michael of Rhodes 15th century manuscript. This has been combined with the framing details of the Contarina 1 wreck excavated and fully measured at the end of the nineteenth century. The details of superstructure and planking will be loosely based on the vessel shown in the Translatio of St Mark painted by Veneziano. Woodrat
  3. INTRODUCTION & RATIONALE I was given the Ancre monograph of the Fortuné Joseph, an Allège d’Arles (the English translation), and, as I was wondering what next to build, this looked like a good possibility. There were lots of variation to these allèges, or lighters, in the 19th Century, but all had in common their lateen rig and general shape. Ever since being taken on an Arab felucca on the Nile (the one in my picture below), I have been intrigued by the lateen rig. I haven’t been able to find any plans or construction details of a Nile felucca (if anyone knows of any, please do advise me), but this Mediterranean version seemed near enough and I liked the lines – so I decided to jump in and try my hand at a build. I have treated my previous builds as a kind of enjoyable apprenticeship, learning the different ways of approaching builds, experimenting with wood and card, understanding the various types of tool that can be used, and getting to grips with plans and CAD. In particular, I have tried to figure out what aspect of model-making interested me most: the type of model, the historical research, the level of detail, the level of skill, the level of accuracy, the general image, the balance between thinking and practical building, the presentation of the model when finished. My first realisation was two-fold: I am far more interested in working or merchant craft than in warships, and completion of the model holds very little interest for me. I simply don’t know what to do with the completed models, other than give them away. The second realisation was that, partly because of my lack of interest in the completed model, and partly because I have nowhere to place them when finished, I would like to explore the creation of small-scale models. I had seen Javier Baron’s 1:200 build of the Allège, and thought that that scale would be an ultimate aim for me, but for the moment I thought I’d focus on a similarly large scale. After seeing kondzik’s build of the card kit of the Allège d’Arles published by WAK, I bought the card kit and built it just as far as the completion of the hull and its planking. This kit seems to be very similar to the allège in the Ancre monograph (although there are lots of differences – such as the dimensions of the quarterdeck) so this would give me not only a good idea of the overall lines and problems that might have to be overcome, but also an insight into the use of card to scratch build a hull. I had had the idea of building hull bulwarks just with card and finishing the rest of a model with wood, as I’d seen someone do that with a Shipyard card kit of the Alert. At first I wasn’t going to make this into a log for a model forum since it really was an experiment just to explore the possibilities as I will explain further on. However, I decided in the end that there may be enough interest in reflections on the Ancre publication to justify a log of my build that is definitely full of mistakes, and a rather ramshackle construction and finish. For these I apologise. The build of the card kit also gave me a little experience with using filler on a card model to provide a good surface for the planking, as so many card modellers have said that without filler it is quite difficult to avoid depressions in the curve of the hull. I followed Ab Hoving’s suggestion of a standard water-based filler. THE PLANS Unfortunately, the monograph and plans drawn by F. Fissore of the allège (as others have noted with builds of the Gemma and S.Caterina) do not match the excellence and comprehensive nature of the monographs from other authors published by Ancre such as Jean Boudriot and Gérard Delacroix. Thus this monograph has a very different approach: the usual detailed analysis of the plans in the monograph is instead merely a list of the parts shown in each plan, there are no scantlings provided for any parts or rigging (we are not even given the dimensions of the keel), and the guide to the building of the boat is almost entirely in photographs of the author’s build (most of which are very small, of poor resolution and thus hard to demonstrate detail). This approach might not be so worrisome to those used to working from plans. It should also be pointed out that the section on rigging is good, especially given the fact that each aspect of the rigging is given its own illustration in the manner of Lennarth Petersson, and this will be discussed later. Another big plus is that the plans are laid out on long pages whose height is that of an A4 page in portrait mode – making it easy to photocopy and then stitch the pages together. [The dimensions of this photo have been modified to avoid replication.] However these positive aspects are offset by lots of errors in both monograph and plans which need correction. My first realisation of problems with the plans came when I compared Plan 1 with Plan 2. They showed the rudder and tiller entirely differently as follows: In this instance, Ancre immediately responded to my request for clarification and they sent me a pdf of a revised Plan 1 which corrected this anomaly – Plan 2 showing the correct dimensions. The anomaly made me study the monograph more intensely in case there were further problems which I needed to bring to the attention of Ancre. I soon found lots. There are four main types of problem: 1. The plans are inconsistent with the method of building shown in the photos of the monograph. (a) There are many details in the photos of the actual build which are not shown in the plans. This led to my having to undo some of the work I had done when I finally spotted the often important detail. One of the many examples is that there are inconsistencies about the number of beams running under the bowsprit fore timbers. (b) Less importantly, the plans show the frame top timbers extending to the top rails throughout, but the pictures of the build showing the method of construction show the frames ending beneath the lower waterway with the timberheads being constructed separately and fitted into square holes in the waterways and rails. The confusion is worsened by the fact that the plans of the frames themselves do not show the position of the ends of the top timbers at all accurately. Of course, once this is understood, the experienced modeller will be able to adapt their thinking and modify the plans accordingly, but it is at first very confusing when comparing photographs with the plans. 2. The second type of problem is that the plans of the frames are incorrectly drawn, especially in Plan 4 of the frames which shows the floors of each frame extending only to the top of the keel rather than to the top edge of the rabbet. Once this has been spotted by the modeller who has been careful to examine the measurements this again will not be a problem. The base of the floors has simply to be extended by a few millimetres (depending on the scale that will be used). 3. The third type of problem is that of inconsistency between the plans. Thus in some the waterways are shown correctly, and in others they are simply not there. There are many other similar discrepancies. 4. A fourth, more irritating problem, is that the numbers on several of the plans do not match the text of the monograph, nor are they consistent on different pages of the monograph. On some of the plans the numbers are duplicated, with different parts having the same number, on some the parts are given the incorrect names (e.g. a rudder blade is given the same number as a top rail; the keel and the sternpost are both referred to as the sternpost); and some parts are given no reference at all. Some of these difficulties may possibly be due to the very poor translation into English (some pages are not translated at all from French, which is itself a translation of the original Italian) but obviously the experienced modeller will be able to manage once aware of the difficulties. All of these are a great pity as excellent models of the Gemma and S.Caterina (both plans by Fissore) have been built (although they do mention but do not detail the difficulties they faced with the plans), and the ships themselves have great attraction. M.Fissore himself shows photos of the builds of his various models including his own of the allège (at Archeologia e Modellismo d'Arsenal) and it is well worth the visit as the photos there are far, far clearer than in the book). I have written a fairly detailed list of these various problems and submitted them to Ancre for consideration by M. Fissore, so it may be that future editions of these plans and monograph will be made more amenable for a wider range of modellers. A very similar boat, La Diligente, which was a lateen Navy messenger boat of the 1750s, whose monograph is published by Ancre and written by Gérard Delacroix & Hubert Berti, has the same level of complexity but is not only incredibly detailed and thorough together with complete scantlings: it also provides a set of plans that will allow the less experienced modeller to make it POB rather than POF. In the interim, as long as one is aware of the problems with plans and monograph, the experienced modeller will be able to use the correct body, sheer and breadth plans on a corrected Plan 1 as the basis for their model. I'll be adding stages of the build over the next few weeks, so I hope it will be of interest. As usual, don't hold your breath! Tony
  4. The lateen rig is not a subject that one can find a large amount of information on when it comes to ship modeling. In most cases, I see lateen yards are located inboard of the shrouds. This makes sense to me, though I then am always left to wonder how one tacks or jibs such a rigged vessel. Now, I've been looking at early American gunboats from the War of Independence as well as those of the Jeffersonian era and War of 1812, etc. There are a lot of lateen rigs there. I'm interested in the Galley Washington, for which there is a nice set of plans from the NRG, plus the monograph. However, one thing that's always bothered me about these plans is that they lack much detail when it comes to rigging. Still, the monograph goes as far as saying that the lateen yard goes outboard of the shrouds. Is it true that some lateen rigs are done this way? It seems odd to me in that with sails up, there are no parrals to hold the yard against the mast, so all the force of wind is taken only by the halliard. What's worse is that the halliard is being pulled sideways from the pulley in the mast top, so it would be constantly be chafing there. It would also be very difficult to haul the yard up in the wind, as the pulley would be next to useless. Now, I get that the main focus is a POF build of the hull of the ship and not with the rig. In fact, if you mount sails, the model plans don't seem to make any allowances for the belaying of sail handling lines, such as the brails or sheets (if that's what they're called on the lateen sail). So, I'm hoping someone can shed some light for me on the lateen rig. Or maybe just on the Galley Washington plans?
