    Yes both port and starboard bulwarks are removable in their mid section for loading cargo. This was discovered in the excavation of the Contarina 1 trading vessel. I believe, and this is just supposition on my part, the bulwarks were slid up and then hung outboard on the protruding deck beams. Incidentally, this would allow sweeps to be used on thole pins inserted in the deck. But there are no illustrations of round ships doing this. Dick

    I have planked the starboard side of the main deck only. Waterways and scuppers to be put in next Dick

    Thanks Steven. Beautiful drawings. The sep de drisse (lower halyard block) is in the position seen in carracks, that is behind the main mast and, as it is a large carrack, is vertically extended to the keel . I note that it has two pulleys as does mine. In my round ship, which is a relatively small vessel, I have elected for a more aft placement which is seen on contemporary iconography. As is the case in dhows of comparable size, fixation to deck framing should be enough. Dick

    This block could deal with the halyard. Was there a diagram of the the sep de drisse? Dick
  5. woodrat
    Yes, fascinating. Here are some snips of the pump: Dick

    Here are the bilge pumps. These were made from single logs (hence their other name: elm tree pumps) which are reamed along their length to accept a simple leather basket . At this period (c 13) the pump was lifted by brute strength but later as in this picture of the Wasa bilge pump, a lever was fitted. Note how the log has been left au naturel and not chamfered as I have done Cheerio Dick

    This is what Michael of Rhodes said in the 15th century. They also could hook up a square sail for running if required. M. Burlet I think is saying there are 2 ropes from the halyard block to the yard. Looks like an interesting book. French is OK Dick
  8. woodrat
    Fantastic stuff, well researched. Does this imply two upper halyard blocks or one upper halyard block with two halyards leading off it. Could it be that the double pulley A 167 is the upper halyard block? This is a large vessel. This is the mizzen lateen from my venetian carrack showing a calcet with a single sheave Thanks, Steven, food for thought. Dick

    Thanks Yancovitch and everyone else for all the likes. The hull framing is directly taken from the comprehensive excavation of a wreck from the Po delta called the Contarina 1. the master frame is taken from a contemporary manuscript, the Libro di Navigar ( see earlier posts for details). As for deck framing, the deck machinery and hatches follow logically from the position of masts but are largely a matter of speculation, especially the knees. No claim is made for this vessel to be anything but a product of my imagination. Steven, thanks for the calcet details. This will be useful. I haven't thought about it yet but there is also the problem of the basket aft of the masthead and the Jacob's ladder to be considered. The Lomellina was a square rigged nave wasn't she? Perhaps this calcet can be adapted for latin rig. Cheers Dick

    As requested, some overall views showing deck furniture. All that is remaining is the log pumps. Still not sure whether to plank half the deck The companionway to the aft accommodation. Ladder to be added. Cheers Dick
  11. woodrat
    Soon to come, Steven, but will do so in a day or so after more additions to deck furniture. Dick

    My concept of the lower halyard blocks and bitts for the two masts. Loosely based on a Black sea find. On contemporary iconography a consistent feature is the halyard angling acutely aft from the mast as is the practice in dhows. This also allowed the halyards to act like backstays. Cheers Dick

    Beautifully preserved wreck and a log pump AND capstan in situ. Wow! Note the transom timber at the stern with a round tuck stern and she is carvel. Not what I would expect from a northern ship of the era. that foremast is very forrard and stepped on the stempost. Fascinating find! Dick
  14. woodrat
    Thanks. Carl. Just call me Simplicius. 😎
  15. woodrat
    Yes, Steven. I made it octagonal for 3 reasons: The slots for the levers are on alternative facets, lessening risk of weakening the log. When winding, it allows the winders on the opposite side to maintain the strain while the next lever is inserted. Thereby a rhythm is set up, no doubt with a shanty to go with it . It looks good. Dick 😎
  16. woodrat
    I have made a simple windlass which is likely to be what they used in the 13th century. No pawls are needed as the windlass could be prevented from running backwards simply by one of the crew pushing his lever all the way through to the other side, effectively locking it. Cheers Dick

    I am happy to help if I can. Don't be too discouraged if it all seems daunting. My first ship model "USF Essex " was way above my head but I took the time, researched the build and bought or made the tools. It took me 10 years but was worth it. Be prepared to modify the kit if it is inadequate or inaccurate. I have all the info you would need to make your model carrack as historically accurate as is possible. Don't be in a hurry. I look forward to your build. Cheers Dick
  18. woodrat
    do you have a reference for this chain pump? I would have thought that simple log pumps would have been used at this time. Dick
  19. woodrat
    It occurred to me that there should be accommodation in the after part of the ship for passengers and ship's master/pilot. Bit difficult to do it at this stage but I thought it important. So I retrofitted the quarters. Very basic accommodation (and no doubt cramped and smelly). The planking is only on the starboard side. I think there would be capacity for about 20 passengers in the steerage Dick

    The mediaeval lateen rig had the sail OUTSIDE the shrouds so if your caravel friend is putting the sail aback against the mast , he must have the sail INSIDE the shrouds which is counter to mediterranean practice of the period you are dealing with ( see prof. Pryor's publications on the mediaeval lateen rig). I will try to get hold of Julian Whitewright's thesis on the mediaeval lateen rig as a basis for the rig of my round ship. The dhows mostly used a settee sail not a full lateen and so I would be cautious using dhows as a model for your rig. It is no longer accepted that lateen rig originated in the Indian Ocean as undoubted depictions of lateen sail rigs date from the second century CE. the settee sail had the forward corner of the sail squared off Your idea of goose-winging the sails while oars are deployed is good. The oars would provide some lateral stability when running before the wind. I am enjoying the build immensely. Keep up the good work Dick

    In order to tack the mediaeval lateener, it was necessary to bring the yard vertical against the mast. I think your crutch forward of the foremast would impede that manoeuvre. Also the lower part of the yard needs to be shorter than the upper so it can clear the forecastle. The best illustrations of this manoeuvre are in Landstrom's "`The Ship". If you are going to depict rowers, are you going to stow the yards on the crutches? Dick
  22. woodrat
    Carl, I have no idea. Wrecks of this period have no decks. The Black sea may tell us in time. At the end of the day, if I am not happy, I can fully plank the deck. There must have been some method of strengthening the deck around the mast partners and bitts to allow transmission of force. Dick
  23. woodrat
    Here is the framing of the mid portion of the deck including hatch and mizzen mast partner. It is largely guesswork but I can assure you it is quite strong. Dick
  24. woodrat
    with regard to the "horns" at the stern, they are consistently shown with round knobs on top. This seems to suggest that the yards could be lashed to the horn, obviating the need for a cross piece. I agree that in port they may have just used removable crutches. Smaller vessels may have taken yards and unstepped the masts, stowing them along the side as seen in the Breydenbach vessel on the left. Dick
  25. woodrat
    Love the crutches but I still think your spur is too long😓. But as long as you are happy with it, thats all that matters. Interestingly the undoubted dromons shown on the Annales de Genes show the spur well. These are not dromons as there is only a single bank of oars Dick 😊
