    Dear All,

    Does anyone have good idea for mass production of aluminum boat?
    For all I know, the GRP boat can use a model to produce quickly.
    Does anyone can provide method is similar to GRP?

    It would depend upon the TYPE of boat
    You may have a chine powerboat , say of trailorable length , that could be cut out on masse
    Set up on a production line as an automobile is and welded off by robot
    All of this would cost 10 squillion dollars to set up and that is why, there are no mass produced al al boats
    If you look at my gallery you can see just why tooling for a yacht would be beyond the means of even a mid sized company

    Hi whoosh,

    Thank for your information.

    I want to find a new method to build a lot of boats.
    I assume that there are different methods of building one boat and fifty boats.
    I want to find a method to building lots of boats. It can save time and money than building one boat.
    Do you have any idea?

    Ad Hoc Naval Architect

    As always it comes down to "design for production".

    If the basic design is poor, it can take for ever to build. If the design has had a lot of thought about procurement, build schedules, sequencing and out fitting etc all taken into account, then it can be done. But not every naval architect is willing to go the extra-mile to satisfy all the other variables, which are ostensibly "not naval architecture".

    As for ideas, plenty, but it depends upon your approach. I have done just as you are proposing, but it takes effort, and not just a flash of pen on paper.

    We need a bit more info before we can go too far in suggesting ways of mass producing a boat.

    1. Basic specs on desired boat. Are we talking small things that one man can pick up by himself? Or are we talking about super yachts designed for a crew of 10 to keep it in order before the passengers even get there?

    2. Material Goals. What do you want to build them out of?

    3. Current Resources: Possible work spaces, possible skill level of the work force, what can you invest in tools?


    If you are going for boats that are larger than what two-four people can use a dolly (on a smooth workshop floor) to push around, then try to go as modular in your design as you can. Lay out your work area so you can have two or three 'lines' coming together to join different parts of the boat, and materials 'flow' in at one end, and down marked out lanes on your production floor to where they are used. A secondary shop could handle production of small components, items that can be handled by one or two men.

    Of course how everything actually works in production is highly reliant on the workspace you have, and the overall tonnage of the boats you are making. If you only have small buildings to house the projects in, then it is better to devote some of them to producing small components, and build the boats 'in place' in the other shops, having the different crews walk between work spaces. Then again, if you are making extremely heavy boats, then it will be counter productive to move it to each new stage. The crews could likely walk to boat waiting for the next stage faster than you could safely move it to them.

    Likely the trickiest part of good mass production is working out a design that you can divide up so different parts scale well and can be finished in very very close times as they are needed. If you have two main parts A, and B, and you produce As at a rate twice that as Bs, then you either have to double your line to produce B, or your A line sits there doing nothing half the time.


    Try to think of your product as a collection of pieces that you eventually bolt together, and each of those pieces are made of a smaller piece that you can produce. The more of those small, simple pieces that are used across different larger pieces, the easier it is to train a workforce to put things together. This does lead to some issues in engineering, such as you can be faced with two different sized brackets of similar size to hold things, and often it becomes far easier to use the larger of the two in all cases.
