    Didn't know you were a sandgroper ( a fond term for native-born west australians). Yes Chuck, I will make stocks as well as 4 more anchors which will be tied down on the stocks on the foredeck, ready for use. Dick

    I think you are right. We call them "honky nuts" here. I made a cooking pot out of it. It is definitely the hardest wood I have ever worked. Dick

    Thanks John , Steven and Schrader. Most kind. I have made the lateen yard using timber found in the local park. I was inspired by photographs of dhows which show that yards were not perfect machine turned bits of wood but somewhat rough and irregular. I suspect this was the case for this boat. cheerio Dick

    Here is the first anchor. Based on the anchor found in the 7th century YassiAda wreck and after blackening Cheers Dick

    As justification for this , a bas relief from Portus Augusti in Ostia second century CE. Which indicates sheaveless pulleys on the forestay and hearts on the shrouds. Note the scuppers beneath each shroud with a rope suggesting that the shroud was looped through the scupper. I have included this on Yenikapi 12 model.

    The mast did not seem to have sufficient lateral support in the absence of mast partners. So I saw a solution to this as used in certain arab dhows and have incorporated it. It also simplifies to process of stepping and unstepping the mast. here is the lower halyard block. I have decided to avoid sheaved pulleys. Dick

    Thanks, Kriswood. Nothing helps, it's just a headache that wont go away. What we call this beast is perhaps less important than seeing if this keelless banana boat is at all feasible as a practical sea-boat. There is certainly no physical convincing evidence for them in the archaeological record (see early posts for all the craziness). Using reverse clinker certainly can produce a hull but would it sail as well as an old shoe? I don't have the computer skills to put the hull into a nautical design programme, but maybe someone out there in MSW Land could do this. Cheers Dick

    I have here a model of a hulc, boys and girls. An ordinary mediaeval transport. I now wish to plot the internal profile of the specimen. Can you get the camera on it? Observe.. I now clamp the ship to the uprights of the experimental apparatus and support its inferior surface. Why do I do this? Because the hull is weak and cannot resist torsional or laterally directed force. What allows me to draw this profile, boys and girls? It is physics! The tip of the probe exerts a force equal to a glass and a half of full cream dairy milk AND the support under the hull exerts an equal and opposite force

    Thanks, Andrew. I fitted the bearing wheels because there was too much friction without them which led to jumping and catching of the slide. Works well now. Dick

    Thanks John and Steven. Louie da Fly complimenting the boat on filthiness is praise indeed. "Straight from rubbish tip to you..." The main problem now is where to place the lower halyard block. The only place I can see that it could go is on the after deck behind the steersman. To back this up I have this 9th century turkish illustration showing the halyard going toward this position. It also shows the "hockey stick" well. And if I'm not mistaken, it also shows a triangular wing on the starboard quarter. And this 7th century graffito shows even more detail" It also back

    The decking is in place and I have filthied it up a treat. I think it looks like a working boat now. Little to do now but rig it. Cheerio Dick

    The first picture is a flat cross section symmetrical rudder on the ancient mediterranean pattern and the second is a foil cross-section assymmetrical rudder of the 13th century ( on my round ship) Dick

    I understood 9th century ACE but your statement still applies. Dick
  31. woodrat
    Thanks Steven, great picturres as usual. Here is a picture to show the course of the halyard. Dick
  32. woodrat
    The way I have done it, the only contact the halyard has is with the pulley and the peg at the tip of the hockey stick. The channel in which it travels is straight. Otherwise the halyard would wear out rapidly. Maybe a second pulley or rotating peg at the tip ?? Still thinking. Dick

About the NRG

If you enjoy building ship models that are historically accurate as well as beautiful, then The Nautical Research Guild (NRG) is just right for you.

The Guild is a non-profit educational organization whose mission is to “Advance Ship Modeling Through Research”. We provide support to our members in their efforts to raise the quality of their model ships.

The Nautical Research Guild has published our world-renowned quarterly magazine, The Nautical Research Journal, since 1955. The pages of the Journal are full of articles by accomplished ship modelers who show you how they create those exquisite details on their models, and by maritime historians who show you the correct details to build. The Journal is available in both print and digital editions. Go to the NRG web site (www.thenrg.org) to download a complimentary digital copy of the Journal. The NRG also publishes plan sets, books and compilations of back issues of the Journal and the former Ships in Scale and Model Ship Builder magazines.
