IF HULLFORM 3 IS NOT ENOUGH ... HULLFORM 3 was the start of a long and continuing development process, the current stage being HULLFORM 6 for Windows and MS-DOS. It introduced the essential fairing and hydrostatics on which which later versions have grown. Version 6 provides a rich set of development tools in a graphical user environment, using menus and dialog boxes for all inputs, allowing a mouse to be used for design editing and input control. You may not need all of version 6's capacities. If not, you can order HULLFORM 6S (MS-DOS) or HULLFORM 7S (Windows 3.1+), which provides a minor extension of version 3's design tools in the HULLFORM 6 for MS-DOS or Windows graphical user environment - plus a full manual. To see whether Hullform 6S or 7S, or the professional Windows or MS-DOS versions cover your needs, read on ... HULLFORM - WHAT SMALL-SHIP CAD SHOULD ALWAYS HAVE BEEN HULLFORM Version 3 brought computer-aided hull design to the amateur and small professional designer, by tailoring the design process to the architectural limits of the basic IBM- compatible personal computer. Version 4, then 5, extended the HULLFORM concept, adding the tools of design optimisation in a greatly expanded program, with a totally new graphical working environment, extra screen and hardcopy graphics support, and design aids, while still maintaining the ability to be used on diskette-based systems. Version 6 saw the program migrate to the for Windows environment, and now version 7 takes the HULLFORM approach into the 90's, and beyond. HULLFORM's Statics Suite With all versions, you can also calculate the displacement of your designed hull, its static design parameters (e.g., waterline, pitch, righting moment) given displacement and heel, as well as several factors related to the hull's performance, such as metacentre position, prismatic coefficient and wetted surface area. The basic statics display is just the start; with version 6 or 7 (not 6S or 7S) you can plot 24 variables (e.g., righting lever, wetted surface, displacement) against each other, write hydrostatic reports to disk file or printer, and test the effects of dynamic waterline changes on hull statics. Hull Viewing Options HULLFORM provides a complete set of viewing options, to allow you to evaluate the aesthetics of your design. Both programs let you view the hull from any angle, including true perspective as well as normal orthogonal views. Using the full version 6 or 7, you can zoom in on any part of any view, view a shaded rendering of the hull, and generate animated image sequences to get a feel for the shape - and save them to disk to show your customers later. HULLFORM's Drag/Power Suite The professional HULLFORM 6 and 7 includes five drag and power parameterisations, including the well-known Standfast series (by Gerritsma and others), two small-ship schemes (Holtrop and Oortmerrsen) and the two Savitsky planing - drag estimation schemes. With HULLFORM 6 and 7, you can complete a preliminary review of the likely performance of your design. The program's drag calculation schemes cover the full range of likely hull types, from displacement to full planing, and you can even compare estimates graphically to see by how much they differ. The Developable Surface Facility HULLFORM 6 and 7's (professional) developable surface analysis tools allow you to review the developability of a hull design, from almost anywhere in the program, with only a few keystrokes. You can plot on-screen the sections of the developed hull and the shape of the flattened - out developed surface, zoom in on sections of concern to see how to fix them, plot or print out the final results, and send the revised hull shape to an AutoCAD "DXF" file. At Whom Is HULLFORM Aimed? The path to the best hull design is not a one-way street, and the best aesthetic shape is rarely the easiest to build, and equally rarely the best performer. The professional designer needs to analyse a hull's static and dynamic characteristics, and its ease of construction, without leaving the design environment. Version 6 provides what users of modern personal computers expect: an integrated graphical enironment, with mouse support and on-line help. HULLFORM 6 and 7 (professional) also provide interfaces to the industry's dominant CAD system, AutoCAD (and most other CAD systems, too), via output of "DXF"-format files. HULLFORM 6 allows development of the design to final shape definition; any further features would be a waste, duplicating those provided by programs such as AutoCAD. But, in spite of its extended capabilities, HULLFORM 6 for MS-DOS (both 6 and 6S) does not abandon its roots. By use of a dedicated set of arithmetic routines, it maintains its viability on even a PC- or XT - standard machine. Normal software-based arithmetic packages are four to eight times slower than a numeric coprocessor, but HULLFORM 6 gives at least 60% of the speed of a coprocessor machine; if the coprocessor chip is run at a slower clock rate than machine's nominal value (as is often the case for old AT-class machines), you will see even less difference. The professional MS-DOS distribution includes both forms of the program - one using the customised arithmetic set, and one with normal floating point routines, which runs faster when a numeric coprocessor is present. Each version (coprocessor or non-coprocessor) will run in the other environment - the former significantly more slowly, the latter only a little faster for most tasks. What Hardware Does HULLFORM Require? To use any version of HULLFORM 6 for MS-DOS, you require: * an IBM-compatible personal computer running PC-DOS or MS-DOS * at least of 512K of memory * a CGA, EGA, VGA or monochrome Hercules - compatible display. Printers emulating the industry-standard IBM Graphics and Epson models can be used for draft-mode hardcopy graphics. HULLFORM 6 also supports 24-pin (Epson LQ) and in the professional version, laser printers (LaserJet and PostScript). Devices accepting Hewlett-Packard plot protocols may be used for high-quality hardcopy output. A mouse is useful, but not essential. You DO NOT need an "80386" machine; you DO NOT need a numeric coprocessor; you DO NOT need a hard disk; you DO NOT need a VGA display. What you have now will very probably be perfectly adequate to run your own hull CAD system. To run HULLFORM 7 for Windows, you require an 80386 or superior system running Windows 3.1 or later, and a 1.44Mb or 1.2Mb diskette to load the software. The full system occupies only about 750Kb, including three help files and sample designs. There is no tailored noncoprocessor version. Naturally, all displays and printers supported by Windows are supported by HULLFORM 7 for Windows. What Does the HULLFORM Distribution Include? You are supplied with a 9 diskette and manual. The Version 3 disk includes the HULLFORM program, a configuration file (which you will probably want to alter) and sample hull designs. The manual describes in detail all the features of the program, and also includes a tutorial introduction, plus a contents page and index, as well as a keyed header line at the top of each page. (Yes, the author is also tired of manuals in which you can't find anything unless you know where it is beforehand). What Does it Cost? HULLFORM 6S and 7S cost only $ 99 (Australian). Why so cheap? 6S was developed readily, using existing routines for much of its work - i.e., most of the bills were paid long ago. 7S is just 6S with the version 7 user interface. HULLFORM 6 for MS-DOS is available for $ 500. If you are surprised at the price rise, remember that this is a full featured professional package. Version 6S and 7S users may "trade up" to Version 6 or 7. See the order form, at the end of this file leaflet - simply return the supplied diskette as proof of ownership - condition not important. How Do I Order HULLFORM? Simply send the following order form, with payment, to: BLUE PETER Marine Systems Pty Ltd, 92 Dyson St, Kensington, Western Australia 6151. Phone: +61 9 474 1288 E-mail bluep@iinet.net.au If you can't buy the program locally, it is because agents so far have not been willing to accept the low profit margin on which BLUE PETER Marine Systems operates. Agents of different attitudes are always welcome.
