    Robert, as I've told you before, you don't need any kind of partner, you need a prototype incorporating your
    "new, innovative hull design for multihulls". The proof is in the puding, show me.

    The best ( and only really ) way to sell your "new, innovative multihull design" is to prove it with a prototype.
    If it really is new and innovative it will sell itself.

    Easy. To easy really. Simple.

    Show it.

    Thanks Tom, for the advice you gave earlier on this and I mostly agree. However, it is a little more complicated than that.
    I quite agree that proof of concept must be made in order to market a product to the buying public. And this is why I made a beachcat incorporating this hull innovation. I chose a beachcat as the vehicle to demonstate the hull innovation's capabilities. So what now? I don't have skills, either in sailing or business to market the product, that is in whatever form it comes in - beachcat, cruising cat or even power cat. This is why I need a partner's skillset.
    Some people have perdonalitues that easily kend themselves to be able to market their product/design. These peiple are also sailors. I possess neither and come from a background which is not sailing.
    I'm looking for someone to partner my daughter's Thai company. I don't want to be personally involved with business management or structure, as my autism is a hinderence.
    I have a beachcat ready for production, tested, finalised and moulds ready. Cheers

    The boat business is not really a place where some new idea takes the industry by storm, or the Chinese take the idea and steal it. The only way to find a partner is to share it and generate interest.

    Consider this offer from me as a critique.

    I have a new innovative fishing boat design and I’m seeking a partner.

    Noone is knocking on that door, Robert.

    Give a little more.

    All the best.

    Thanks for your positive input. My openness to share all the details is there, via my direct email. But not on a public forum like this. At least not yet.
    If I go down the path of securing IP rights first, then I could openly reveal all the details on this or any public forum. That said, it's still the case that it will not be believed or fully understood until, as Tom states, it is demonstrated. So, yes, it is a bit of a catch 22 for me at the moment.

    What I can tell you is that my new design innovation is referenced to both applications of multihull sail and power. The outcome is different in each application simply because of the fact that hull design is quite different for sail and power cats.
    In powercats, it relates to asymmetric hullshapes, specifically relating to bow design.
    Benefits are;
    * Reduced wave interferance on the bow
    * Widened deck outline at the bow, producing a bigger 'mouth', equivalent to a Vee hull design.
    * While still retaining the benefits of the asymmetrical hullshape of speed and efficiency and the positive handling characteristics such as banking in turns.
    The application to sailing cats is quite different and relates to the whole underwater appendage of the hull. The benefits here are;
    * Fast and efficient hullshape
    * Ultra low draught
    * No dagger boards
    * excellent resistance to lateral slip
    * simple, easy to construct hullshape
    * can be manufactured from flat sheet

    Is it the same or quite different? You are contradicting yourself, which makes the claims not credible. Since you claim to have built one, how about posting a video of the boat handling the way you claim?
