  1. This can only be done if the sail is inboard of the shrouds. In mediterranean vessels of the mediaeval period, which I suspect includes the dromon, the sail was outboard of the shrouds (Landstrom and Pryor) Dick
  2. The mezza lune technique was used as a geometric method of calculating narrowing of floors, also in many cases rising of floors and even the cutting of curved sails. A semicircle is drawn with a radius equivalent to the total amount of narrowing between master-frame (the frame in the centre of the keel) and tail-frame (last molded frame on each end of the keel) the number of frames between master and tail is decided e.g. let us say 6 (inclusive of tail, master-frame is 0) The 90 degree arc is divided into 6 X 15 deg segments Where the segments cross the circumference transverse lines are drawn These divide the radius into a geometric progression This progression is marked on a stick called a sesto and is used by the shipwright to draw out the floors with appropriate narrowing I hope this is vaguely comprehensible. But this seems to be what they did. Dick
  3. the master frame modified again.. Note the flat floor amidships which is exactly 1/2 max. breadth
  4. Thanks for the likes but feel free to dislike. Here is the plan for breadth and floor lines. Narrowing of floors based on the mezza lune geometric technique Mezza lune Cheers Dick
  5. The new master frame modified according to the instructions of the Libro di Navigar. My previous depth of hold was incorrect. Interestingly the master frame now matches that of Contarini 1. Dick
  6. More information has come to hand thanks to the kind assistance of prof. Mauro Bondiolo. This is a 14th century manuscript, the Libro di Navigar, which has only recently come to light. This substantiates the basic premise of my reconstruction but means a slight modification of the geometric method for constructing the master frame. However the main dimensions of my hull are consistent with the Contarina 1 hull. I will use the mezza lune technique for calculating narrowing of the hull between master and tail frames. Cheers Dick
  7. the halyard, at the end of the day, should pull the yard away from the mast so it runs smoothly as it raises and lowers. I believe there should be a line which pulls the yard against the mast once it is in the correct position and is released for tacking or changes on yard position. I show the arrangement on my carrack. Athough the dromon does not have parrels, the principle is the same. Keep up the good work. Dick
  8. Thanks, Carl. Signor Penzo is a great modelmaker, historian and author documenting the many ships and boats of Venice and the Adriatic. His plans are meticulously researched and his models made using original techniques such as the sesto to reproduce the lines. I thoroughly recommend his plans. I have not yet met him and have not had a reply to emails. Maybe the language barrier? Anyone visiting Venice needs to look into his shop. Dick
  9. This is a first draft of the nave latina. The dimensions are taken from the Michael of Rhodes manuscript and combined with the known lines of the Contarina 1 wreck. The superstructure will be based on the ships painted by Veneziano in his cover for the Pala d'oro in the Cathedrale San Marco, Venice Cheers Dick
  10. Best not to look too close, casting is not my forte (yet). You should have seen the first versions Dick
  11. Have made the anchors from woods metal and wood but am trying to determine how they were secured. I have made a decorative stand more in keeping with the period using playful dolphins and perspex to support the nave. Cheers Dick
  12. Hi Kensaku. A very nice cutaway carrack. Could you open a topic in kit built models forum? We like to see the build if you have recorded it photographically. Certainly, if you do any more kit builds of this quality, we would love to see your work as it progresses.

      Hi Dick. I'm happy to be complimented on. I develop a model kit and sell it. I wanted everyone to know and posted. Do you want to see something like the attached image in the process? Kensaku

      Yes, photos like this as well as information into the research involved in the kit development. This seems to be based on the Martinez-hidalgo Santa Maria.

      OK. In the future we will also make the process of development public. Thank you:dancetl6:

  13. The steps sit on the keelson with knees either side. As you say the keel is not cut into. The knees are either part of the floor or bolted into it, I think similar techniques were used in galleys but they were lightly built. Dick
  14. As requested, Steven. It wasnt a galley but it was a lateener and at least the foremast, if not both, was canted at about 20 deg to the vertical. The mast foot may have been shaped to allow this. Dick
  15. The Contarina 1 wreck excavated in about 1899 had its mast steps intact. They were not raked although the foremast was canted forward being a nave latina Cheers Dick
  16. Me gusta mucho Dick
  17. Thanks Carl and Jesse. The next project, a 13th/14th century Lateen-rigged two master is well advanced on the drawing board and will hopefully be as interesting. Dick
  18. Thanks for following, Druxey. I appreciate all the feedback Dick
  19. Thanks Götz. Yes, indeed. A coastal highland of some distinction. Dick
  20. The build almost finished. Flags of the Moro family in place (silkspan). Note: the Moro family crest consists of bunches of blackberries. This is a pun on the venetian name. The original name of the Moro family was Mauro or a moor. This was corrupted to Moro which is also the italian for blackberry. I have only the anchors yet to make. Dick
  21. 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
  22. what did they do with the oars when running before the wind? Were they pulled in and locked? Dick
