    Hello everybody!

    After downloading Freeship 2.6 (yep, my computer is quite old) I learned how to use it within a few of weeks. Now, I feel I can show you my work. I got in touch with the webmasters and Martijn told me it’s O.K., but I’ll have to limit the files size:

    You can indeed post the pictures on the forum, just as long as you keep it down to a reasonable number.
    Also the size of the images you can upload is limited to max. 800×800 pixels and 750 kB.
    You can also upload your delftship model to the forum, and in that case the maximum size is 8 Mb.

    So here is a sample of my work… don’t be surprised: FreeShip can do more than ships! 😉

    Today I am working with the 4.46.158 but the ships made by 4.27.101 and 4.38.130 Free versions.

    Question: Is here any from Hungary? Van itt magyar tervező?

    Question: What part is this ship missing?:dry:

    Answer: Since it’s a prao (non-symetrical ship), it isn’t missing a hull. I just have to add the rudders and anti-drifting fin.:side:

    Hi everybody,

    here is my last – still unfinished- model. (An Arab saying is: When the house is complete the owner dies. So leave things uncomplete!)
    The ship is an “Schebecke” of algerian corsars of the 18th century.
    This “Latin” Rigg gave them crucial(!) anvantages over yard rigged ships.
    They could go much higher to the wind and easily and quickly could go through the wind…
    Data are extracted from Fredrik H. af Chapman “Architectura Navalis Mercatoria” of 1764. Reprint edited by Delius, Klasing & Co, 1984.
    The Rigg is taken from Marquart: “Bemastung und Takelung von Schiffen des 18. Jahrhunderts”, VEB Hinstorff Verlag Rostock, 1986.

    I know this is not the use Delftship is made for, but I love the program and have learned now by extensive use of export and import to get what I want…

    Have a good time all together

    Hello Michaelf!

    As you must have noticed it, I’m using the Delftship/Freeship software for much more than what it was designed for. I consider this as a way of trainning, of getting “acquainted” with the software… without getting bored. 😉

    I like your arabe saying, and it reminds me a so-called mexican one: “Mañana, amigo! Mañana…” that means “Tomorrow, my friend! tomorrow…”.

    I’m very interested in your Schebecke bacause I’m working on designing a kayak, and I’m thinking of using a Latin rig. But I’m affraid the front part of the sail can block the sailor’s lign of sight. Do you have an opinion about this possible disagreament?

    Meanwhile, here you have my vision of a hull… made for speed! :silly:
    Can you see the slight evolution of the project?

    Hi, Icare,

    for some years I did white water canoing with a kayak somewhere in Bavaria, Austria and Switzerland. So I am much interested in your kayak development.
    My son actually is kayaking on the Baltic Sea, but he relies on his arms, not on a rigg, even when crossing from Sweden to Finland…
    The problem of the rigg being in sight of the man at the steering wheel is very old: but he is not alone on the ship. These yard sails under the bowsprit in use up to the 17th century were called “blinde” because they made the man at the rudder blind.
    It is a more ore less theoretical problem.

    As an answer to your nice Canadair-like water planes: For many years I plan to make a flying model of the “Dornier Whale” used by Roald Amundsen to fly to the north pole. The story is most interesting but it seems not to belong in the D.S. forum…

    Thanks for your answer

    My next model in Delftship could be a Dornier Whale

    Hi Michaelf!

    As matter of fact, when I draw my flying-boat, I was thinking of a Dornier’s hull (stabilizating fins) with a Bereiev’s wing (seagull wing).

    I don’t consider the Dornier Whale as a specially beautiful plane, but I think your choice is based on patriotic considerations (“For Sverige, i tiden“?), isn’t it?

    Since you’re interested in my project of kayak with a latin sail, here you have a first sight of it. I draw the man just to make clear the reason of my perplexity about the man’s lign of sight.

    Here’s the “San Jacinto 88” I mentioned in my Twin Keels In and Hyrdostatics Out query:

    SanJacinto88Ctwinkeel.jpg

    So … how do you get the thumbnails and non-downloading pop ups for this forum? :unsure:

    EDIT: I used Eric Sponberg’s presentation on The Design Ratios (http://www.sponbergyachtdesign.com/THE%20DESIGN%20RATIOS.pdf) to look at this boat in-so-far as it’s presently possible. There appear to be some good things about it.

    First, as it heels over the Center of Flotation seems to move forward slightly (which Sponberg claims would help in pointing higher).

    A Displacement/Length Ratio of approximately 219 makes it a light cruiser by Ted Brewer’s classifications … not a racer, though with gobs of sail (SA/D of 23) it would have good performance (S# of 3.1 or a borderline “racer”) according to the S# calculation provided; but, even with a modest SA/D of 14 the S# is still 2.1 … still a “cruiser” and not a “lead sled”.

    Motion Comfort Ratio seems to suffer if I use its ‘actual’ waterplane area coefficient (which is 0.771 … SJ’s meant to be roomy) rather than the generic “0.65” used in the equation but still promises a better than average but still in the “average” range level of comfort even with an SA/D of 23 (and better than average comfort with a mere SA/D of 20) … I like

    Stopped cold at trying to figure the Dellenbaugh Angle though, since that seems like it would take figures from an actual rig design.

    This is fun! 🙂

    I have been following that thread. The problem does not seem to be how to model the vessel rather then where to obtain reliable information. You will need a very accurate hull shape, compartment layout and last but not least a list with all protected/unprotected openings in order to produce reliable results for the damage stability calculation.

    …And don’t forget, The uploaded files must be quite light because the DeftShip server has NOT an infinity of storing space (check for the very first post on this thread). Personnally, I upload only JPeG files, 800×600 pixels and with a size of 100 Kb maximum.
    The DelftShip team is kind enough to allow us to upload pictures just for fun, so don’t abuse!.

    DasBoot: I assume an impportant piont is what’s the vertical position of the Center of Gravity, and this point is known by the shipyard only… if someone does… Anyway, it must be on a quite high position, as it is on any modern liner. Nothing to see with the World War II battleships.

    We have data on loads and KG. Beside there is a retired NA professor on the Forum who review & comment our work. We just need a FS/DS artist who can ‘hammer’ the plating better and faster that we can (at our speed the salvage will be completed before the model is). completed)

    Thanks for your reply. As you suggested on your post in the other forum, we are first going to work on a lines plan and use it as ‘background image’. This should make the modelling much easier and give us a better model. When our hull get ‘close’ enough, we will submit it for your review.

    Buenos dias SD-Naval, or am i wrong and are’nt you Spanisch.

    Tnx for the complimentents. its a hell of a job creating this although the program is wonderfull.

    Especially for modelbuilders like i am.

    I am building the OPV Zeeland (P841) right now according to drwaings from the Damen Yard, second edition.

    Also i am trying to create the hull from the A800 and A803 Karel Doorman the new JSS.

    Hello Ian,
    I see you are a “pro” modeller and/or designer. Quite a detailed and nice model you have. congratulations…!! I guess it should be quite difficult to get the X-bow lines in the “open market” although I found the US patent document (internet) from where one can extract information to start modelling,
    Best regards,

    Hi sergio,

    Thanks for the comments. I am not a ‘pro’ modeller in the formal sense, just a hobby modeller.

    However, having trained as a marine engineer does help.

    I developed the model from photographs. The yard and owners wouldnt give out a lines diagram.

    I haven’t seen the patent document, but will look now out of interest.

    2 Jurgen 54,

    I must admit, your way of drawing looks much more professional then mine.
    I hope to get there one day.
    As i look back at my drawing i can see the whole learning process from having no clue to “hey i could have done that much simpler”. if i had to do it over, it would look better but the basic outlines i still like. and i’ll leave it as it is for now, including all those red lines :whistle: .
    I’ve done some redrawing on the prop though because that one in the first drawing realy was’nt accepteble :laugh:

    Hello DelftShippers, or skippers ( the lucky part of you ).
    Since August is meant to be best month for sailing – in northern hemisfere almost – here is something appropriate:

    It’s been a long time that naval engineers has tried a commercial solution for the idea of sails applied ( again ) to merchant vessels.
    Now, thanks to high price and pollution figures of bunker fuel, somebody is taken it seriously.
    Rolls Royce for ex., they run a joint venture with some b9 enterprise to fix a general concept suitable to attire investors…

    For the rigging: fractional wings on rotary masts, again the idea comes from the past.
    Designed in the ’60 by Wilhelm Proelss.
    A modern astonishing ship that has used ( and developed ) it, is the Maltese Falcon: have a look on Wikipedia and on Youtube.

    Hope all of you enjoy this little contribution.
    Jurgen.

    P.s.: There’s an error in the file: if you try the hydro. data, you must change the draught from 0.3 to 3.00 meters.
    It happened I scaled up the model and forgot the change!

    It’s a Houseboat!

    For a while now I’ve been toying with the idea of a sidewheel yacht with the wheels nestled between stabilizing amas (roughly 10% of displacement) and a somewhat narrow, 7-to-1 LBR, shallow draft hull. In larger boats (say 70′ or more) this actually seems to work well, and allows for a huge party deck on top of the main cabin (the roof line for this deck is level to the bow), aft of the pilot house. Going by the DELFTship power estimates, even assuming just under 64% propulsion efficiency between a assumed piddling performing feathering wheel and lackluster diesel-electric, such a boat seem to offer very good economy for a cruising speed of 10 or so knots with some modest dash potential.

    Unfortunately I can no more afford a 99′ yacht than I can … well, a LOT of things. Even, sadly, this 39’11” scaled down concept (well, most likely I can’t … pity no one I know is tearing down a century old barn made of native live oak).

    You may note that it isn’t a paddlewheel but has twin Glen-L style electric drives made from outboard bits. Shown are the props for 15 kW motors, their housings possibly hidden beneath some bench seating. The 10″ prop for this power is also the largest that could be put under the boat without resorting to deeper protective skegs. DELFT calculations say this would give me about 10.6 kt max and 9.2 kt cruise (80%), again about 64% efficiency (just because assuming “mediocre” seems a way not to be the-bad-surprised if it ever were built).

    I would like to thank J.Sass for the outboard model from which these details were cut and scaled.

    Abandoning the paddlewheel for this boat was done because having them with a 5-to-1 LBR main hull (and more supportive amas) and properly wide wheels made the thing look ponderous, though not necessarily unattractive, and would have also added a lot to the cost of construction as well as weight (besides, long ago I decided that for this length and smaller using a quarterwheen trimaran/pontoon arrangement works best in terms of internal layout: the engine bay and head being nestled between the wheels leaving the rest of the cabin open, extending over the wings a few feet, and still managing to keep the profile down a bit).

    You may also note that the amas are unattached. This is because I’ve yet to decide on the style of wing. For a boat like this something industrial, maybe even an exposed painted truss, might look suitable. I’m not really committed on wing style and thus none is shown. Not even to having the amas at all (the program indicates only needing 10 kW motors for the above speeds as a true monohull), truth be told.

    EDIT: just realized a mistake with the power assumptions. Previously I’d got in the habit of thinking about the genset end of things and not the motor driving the wheel. Looking at the motor end of things that means their power could be 10% less than stated above. Okay, not a huge difference but at least it allows the resistance calculations to be somewhat rosy and it not matter as much.

    After a long while I’m back on this thread with my latest creation… a strange machine.

    It’s a car body (with five seats) mounted on a motorboat’s hull, lifted by hydrofoils and powered by an hydrojet.

    No, I didn’t plan to build it, not even as a scaled model. But if there’s a naval engineer among us, I’d be glad to hear his opinion ;o) 😆

    been playing around with FreeShip for a couple of years and read up on Larsson and Eliasson Elements of Yacht Design plus a whole lot of stuff on the net.
    I have a sailed for many years and built 2 boats.
    This is my idea for a budget fast short handed 11m performance yacht using medium tech materials.
    displacement is just under 3T in light ship mode.
    The chines are at the 15 deg waterline for stability and ease of steering especially down wind under auto pilot as well as simplifying
    construction.
    the prismatic coefficient is high at .64
    with a sail area to displacement of around 35 and a displacement to waterline length of 70 she should still go in the light
    mast is alloy, sail plan is a self tacking jib backed up with a code 0 for the light and a roachy main, assymetric spinnaker downwind

    ballast ratio of 55% in a bulb with 2.3m draft will make for a stiff yacht with strong upwind performance

    other dimensions are
    LOA 11 m
    BMAX 3.3m
    LWL 10.5 m
    Bwl 2.2m

    RM1deg 125 KgM

    Suggestions welcome especially regarding stability calculations and VPP. I would also be interested in thoughts on merits of hard chine or soft chine especially down wind in planing conditions. I believe this boat will full plane in 20kts tws or less. with 160 m2 sail area.

    This can happen… depens on what picture hosting service you’re using. Some of them erase the picture after a few of days/weeks… :S

    Furthermore, as creator of this thread, I strongly suggest the users to limit their pictures’ size to 100Kb (check for the parameters when saving the screenshot). This will leave HD space on the DS server for more important threads. :whistle:

    I checked for the book you mentionned: Nice reading! It’d be delivered with our favourite software… B)

    About the hard/soft chines question, I ain’t a good judge, I never build a real ship. I just can report that a friend of mine told me long ago that soft chines were easier to build… on a RC scaled model. I assume it’s true with real models, too. 😉
    But, in another hand, the south-east asian traditional pirogue is called “sampang” that is “three planks”… :whistle:
    I noticed, too, on the Vendee Globe Challenge sail racers they used both: soft chines on the fore part, hard chines on the aft part of the ship.
    Maybe the answer is in the book you mentionned… :cheer:

    3) Chines are easier to build in my opinion, having a hard chine at the waterline sneaks a little more water line beam without much extra displacement and so increases righting moment. It is planing and surfing where I am concerned, Eliasson and Larsson refer to chines and planing strakes as a way avoiding increased wetted area by deflecting and disattaching the flow creeping up the hull sides in high speed conditions. A hard chine also seems to give directional stability at high speed.
    4) I have been looking at the Vendee Callengers and Class 40s and aft chines may well be the way to go, just I havent mastered the transition on the software without getting an ugly bulge in the middle of the boat.

    About the last problem you mentionned:
    Right now, I’m not using my computer (the one with FS installed on), but I think the solution is to draw three parallele lines (on the side view) from bow to stern. In the perspective view, on the bow, their origin will be lined up meanwhile on the stern their end won’t be lined up at all.
    Then set the middle line on “hard chine”. I assume you’ll get a pretty good result: on the fore part, the hard shine will look soft (all three lines being in the same plane).

    I hope my english is understandable and my method will work. 😉

    I’m back with an example I quickly made!

    The three lines I used to make an evolutive soft-hard chine are the two selected chines (yellow) and the concerned chine (enclosed between the two others).

    As you can see, the “hard chine” option seems useless on the fore part: the three lines are on a same plane.

    But on the aft part the “hard chine” option becomes more and more effective: the three lines are no longer on the same plane.

    I annexed the FBM file, I hope this will help you.

    A boat has been under repair for years in the port near my place. It’s a racer that, I assume, crashed and a mechanic bought the wreck to rebuild it.
    She’s strange… The screws are facing the bow and the helming system looks like airplane’s flaps.
    I tried to render her figure from memory in this project (10 meters long!).

    ¡Gracias Cruz! Veniendo de ti es un honor.
    Thanks Cruz! Coming from you it’s an honor. B)

    Tell me, I need an engineer advice: Do you have an opinion about their helming system? Do you think these flaps can change the boat rolling angle and then change her route? Will it work even at low speed?

    The flaps are assistants for stability pourpose mostly, can help with turning the boat also, but mt guest for the image is that propellers are some how Azimuth (Z Drive) and they turns some angles, so the change in direction is a combination of turning the propellers and the flaps position, and of course the flaps won´t help much a low speed, my experience is with bigger boats and not race, but that kind of flaps are use in small yachts for help having a steady transit, and they help in speeds above 7 knots mostly.

    Thanks Cruz!

    On the next time I’ll go to the port, I’ll have a glance at the screws’ support, to make sure there’s some kind of mobility along the vertical axis. 😉

    Hey Cruz! Is there a possibility that you can add a file so that I can download this model?
    I have this school project where I am supposed to create or download a project for Delftship and create a real life RC model out of styrofoam. Then we are supposed to have a race. Me and my friends are trying to make ours similar to the The Benchijigua Express. I have tried my best at recreating this ship on my own, but I don’t have enough time to learn this program and create it myself :/

    HI send me a mail to cruzmayora@hotmail.com , keep in mind a couple of things, 1. Is not accurate I develop the model from pictures and the main dimensions of the original, so there must be difference between the model and the actual design, 2. The original design is not mine so please give credit to the original designer in your work, 3. It would be nice if you send me pictures of the styrofoam model and some info about the performance of the model.

    Best Regards

    I hope this selection of my most presentable models will fire your imagination. Their length ranges from 1.78m to 237.55m, and they are not only ships. :whistle:
