    Roger,
     
    Quite the career you had there. Thank you for sharing and thank you for your service in the Navy. I am prior Air Force, but for some odd reason I have always had more interest in ships than planes. Never been able to figure that one out. 🤷‍♂️

    Brian,
     
    No I was not a pipefitter, but like you I have great respect for their abilities. IMHO, they are the aristocrats of the building trades.  Few people probably realize that they are graduates of a demanding four year work study apprentice program.  Much of what they do requires an advanced knowledge of trigonometry.
     
    I came into the piping industry via the back door.  I am an engineer with a degree in Naval Architecture and Marine Engineering, and a commission as an Ensign in the naval reserve.  Upon graduation I was ordered by the Navy to report to Admiral Rickover’s Nuclear Engineering organization where for the next four years I worked on nuclear submarine piping systems.
     
    When I left the Navy, I was hired by a large engineering company, that was building piping systems for civilian nuclear power plants, as their quality assurance manager.  I went on to other engineering and management roles, all involving high pressure piping.  It is a small but fascinating industry with its own technology.

    Mustafa,
     
    Thinking that you might not be able to run DELFTship, I created the nine stations you would need to hand draft the plywood planks in my 2D program. This is what I came up with:
     

    A couple of issues are evident. The main problem is that the body plan is not consistent with the profile and plan views. So you will be able to use that view only for general reference. I think you can get all the important details from the other views. Also, the image is slightly tilted (less than half a degree), but that can be enough to throw off some dimensions. I corrected the tilt in this image.
     
    Even with a lower-resolution background image, you should be able to adjust the the chines to create fair edges for your plywood planks. If you view the surfaces using the Developable tool——you should be able to adjust the crease edges to create a completely fair surface.
    What you are looking for is a solid green color indicating the surface curves in only one direction or is perfectly flat. This means you can cut the plank out of a flat piece of plywood stock. Usually the program will show red shading near the edges, especially if the edges themselves curve in more than one direction. This is how my brigantine's cylindrical transom looks because of this effect:
     
     
    As far as sizing the background images and other considerations for starting a DELFTship project, see my tutorial available at this page here in this forum.
     
    Again, contact me if you need some assistance getting started.

    Late 2012 Mac running Mojave 10.14.6
     
    Using Wine/Winebottler I have Delftship v5 working, but can't get v10 or 13 to work.
    v5 is 32bit as is Freeship v3.4 which I also have working.
    The new Delftship v13 is 64bit, as is Freeship V5 which I can't get working either.
    There are problems getting some 64bit programs to work as Wine is a 32 bit program. There is no 64bit Wine version for Mac, so it will only work properly in Mjoave (10.14) or lower, as Catalina is pure 64bit and won't even run OSX 32bit apps.
    Also it appears OSX deprecated OpenGL3 in Mojave and above for Metal.
    If you want to try either on a Mac you really need an older 32bit version.
     
    It looks like either dual booting or a virtual Windows environment (Virtualbox, Crossover - who say they've got it running, Parallels) is the only viable solution for some programs.
     
    Hope this helps a little.
    Bob
     
    A small update.  Using Virtualbox and Win7 64bit installing delftship 1330_334 on a Mac Mojave 14.6 it won't run.  However, putting the file opengl32.dll into the same directory as delftship.exe it starts and runs. Tweaking the Vm settings for RAM and Video RAM will get it to work at least usable.

    I think DELFTship is a Windows-only platform, sadly.
     
    But like Roger said, you can create stations along the length of the hull in both profile and top views. Then pick off heights and breadths of the "chine" lines at each station and plot them in the body plan view. When you connect the dots with with straight lines at each station, you have your third view.
     
    The harder part will be generating the true shapes of the plywood planks. I think this can be done by drawing diagonals in the body plan view for each plank, then picking off the distances from the associated diagonal of the top and bottom edges (chines) at each station. This sounds more complicated than it actually is. [Edit: If there is a twist to the plank, I'm not sure this will actually work.]

    Hello Mustafa,
     
    I think it may be doable. The interrupted lines in the plan and profile views represent edges of developable sheets of plywood. The body plan view can provide the true widths of the sheets at the dead flat point. So your software should be able to create the necessary pieces in 3D.
     
    Does your software "unwrap" surfaces to create the plywood templates? If not, I recommend DELFTship Free. This program also allows you to create truly developable parts using visual cues such as solid colors.
     
    Let me know if I can be of further help.

    This would not be hard to do as this is a “hard chine” boat.  The dotted lines represent the chines in each view.  For each section simply measure distances from the centerline in the plan view and above and below from the waterline, plot, and connect the points with straight lines.  No CADD program is needed.

    Hi, anaxamander49.
     
    I have attempted creating ship plans in Sketchup, Blender, Fusion 360, and DELFTship Free. All of these are open source, have free licenses for hobbyists, or are offered as a free version of the professional software.
     
    Sketchup creates surfaces in polygons and there is no utility for creating useful hull plans that provides the information a ship model builder needs (e.g., stations, waterlines, and buttock lines). Also, if you attempt to scale down a full-sized digital model to model size, you risk losing precision in fine details due to the way Sketchup works (points, lines, and polygons simply disappear!).
     
    Blender and Fusion 360 have (very) steep learning curves and, again, they don't really lend themselves to creating 2D building plans useful to ship modelers without a lot of fiddling around. While Blender is an amazing program, its developers are continually revising the features and interface, so a casual user never gets up to speed in the program.
     
    DELFTship Free, in my opinion, is your best bet for creating useful working ship model plans. The program's 2D plan output shows the hull and expected details in standard profile, body, and plan/halfbreadth views. These views can also be customized to show specific objects and omit others, if desired. The program can export 2D DXF images in polyline format that can be imported into 2D vector graphics software for editing and formatting. In addition, the model surface is a true subsurface object that can be precisely shaped with a customizable control net to match existing 2D plans, if required. Like you, I used the program to reconcile incompatibilities among the three views of an existing set of hull drawings that I have come to believe was an unknown mixture of conjecture and actual measurements. The result was a fair hull that seems to reflect contemporary photos of the ship.
     
    If you haven't already, I recommend reading through the many topics within this CAD and 3D Modelling/Drafting Plans with Software forum pertaining to the various 3D software others have attempted to use when creating ship plans, and then draw your own conclusions.
     
    If you are having difficulties getting started with DELFTship (the manual isn't very good on work flow or process, just feature capabilities), please contact me or the other members who have used the program. Having a guide can help you past many of the frustrating aspects of this program.
     
    Best regards.

    Hi and welcome to my second build, the brigantine “Matthew Turner” from Modellers Shipyard.
     

     

     
    I have not yet completed my first build but wanted some variety and experience building a next-level-up model, as it were.
     
    A little history about the Matthew Turner: (Taken from Modellers Shipyard website)
     
    Launched at Sausalito, California in April 2017 the brigantine Matthew Turner is the largest wooden sailing ship to be built in the San Francisco Bay area in more than 100 years. Built of Douglas Fir and Oregon white oak. The Matthew Turner has a length of 132 feet (40m), a beam of 25feet (7.6m) and a displacement of 175 tons (160 tones)
     
    The ship pays homage to the ships namesake, Matthew Turner (June 17, 1825 - February 10, 1909) was an American sea captain, shipbuilder and designer. He constructed 228 vessels, of which 154 were built in the Matthew Turner shipyard in Benicia, California. He built more sailing vessels than any other single shipbuilder in America and can be considered the "grandaddy" of big time wooden shipbuilding in the US Pacific coast.
     
    The main inspiration behind building the Matthew Turner was the Turner designed brigantine Galilee, launched in 1891. Galilee spent much of her career as a packet, making swift passages back and forth between San Francisco and South Sea ports. She ended her days on the Sausalito mudflats - Galilee Harbour is named for her - but her stern is preserved at Fort Mason and her stem at Benicia.

    This model of Matthew Turner is expertly designed with a keel and bulkhead construction. A unique feature of this kit is that it has fairing laser score lines on the bulkheads to make the fairing accurate and symmetrical. All laser cutting is clean and crisp and all parts and fittings are of the highest quality. The English building instructions provide highly detailed step-by-step descriptions supported by colour photos of the model being built. The model is single layer planked.
     
     
     
    Why did I choose this model? Several reasons:
    It's a very handsome ship
    I have a penchant for sail training ships 
    It was from the same manufacturer as the brig Perseverance which I am currently building and I am very happy with the quality of that model.
    It is a next-level-up (Lv3) which I felt I needed to undertake before immersing myself in the Gorch Fock (Lv4).
    The support from Modellers Shipyard was/is excellent on my current build.
    The availability of the 4 DVD set of instructional videos is a huge bonus for this novice builder
    Because this ship is so new, there is an endless supply of photos, videos and all sorts of reference material available all over the NET
    It was on sale, yesssssssss 🙂
     
     
     


    Cant say I like the laser etched deck planking, I rather enjoyed doing my own planking.
     

    Notice the fairing lines laser cut into some of the bulkheads. I don't know that it is a particularly unique feature as I seem to recall having read about them previously.
     
     
     


    I have noticed that some of the smaller parts like blocks, pulleys and deadeyes are of a much higher quality than say those supplied with the OcCre Gorch Fock.
     

     
    So that's the kit and I hope to be setting sail with it in the coming week      
     
    For anyone interested in the real deal, here is an excellent starting point from Call of the Sea
