    Hi everyone ,

    I m a Naval architecture student and i have some questions about designing.

    I would like to design a tugboat (like 15 mt) and i have some experience in Rhinoceros.

    The problem is I dont know where to start and which processes do ı have to follow ...

    Could you please give me some idea , information , pdf's that i can read.

    The idea is to start designing a boat till to its ready for construction.

    Obviously you've just started your career as a "Naval architecture student", so it's best if you begin small, say a 3 m skiff and work your way up. A 15m tug is a very complex structure, a 3 m skiff considerably less and considering your current experience and skill levels . . .

    What year of your naval architecture studies are you in? Is designing a tug part of your studies?

    This is our last year ... All we know is theoretical knowledge thats way we dont know where to start in designing in cad programmes . Tugboat is an example for me the aim is to learn the process and start designing from one point

    I hope that you are actually saying that you don't know where to start from in using the Rhino tool, and not that you don't know how to start the process of designing (calculating, engineering) a ship?

    In addition to a Statment of Requirements, collect information on existing designs from websites, journals and magazines. You will probably need to spend some time in the university library.

    Most engineering education I'm aware of concentrates on analysis and calculations, and spends little time on geometry creation, selection of materials and components, budgeting, and synthesis in general. Good design is a combination of all of these. The toughest part of the design process can be starting and getting onto the design spiral.

    - Study SOR;
    - Collect info on similar vessels and their operation; Significant Small Ships and Boat International might be good references to look at;
    - Take one of them as 'parent boat' and try to adjust it for Your requirements;
    - Make first sketches of GA and weight estimates
    - ....

    Using Rhino (or any other hull geometry/hydrostatics tool ) is most pleasurable but very small part of design process.
    SOR, how much all the parts (design, build, operation) will cost/weigh/shift CG, idiosyncrasies of owner, builder, you ( :) ).
    General arrangement, systems that do not fit in cost/weight /space/(electric) power/whatever budget...
    All this take more time and especially "thinking power", not to mention nerve and communication skills.

    Did someone explained (in a process of education) a concept of "Design Spiral"?
