woodrat Posted April 11, 2020 Share #1 Posted April 11, 2020 (edited) 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.
