    I want to design 19' shallow water V monohull with a reverse chine, a beam of 72" and depth of 24". What parameters should I be paying attention to when designing a shallow water hull? ( i.e Hydrostatics, Deadrise angle etc..)

    Can anyone point me towards right direction or suggest a paper or a book?

    Thank you for your time.

    What do you mean by "a reverse chine"?

    Any existing boats with similar characteristics? Is this to be an open "flats" fishing boat?

    What speed is desired?


    What is your knowledge of boat design and overall technical knowledge?
    Performance by Design by D L Blount is probably the best reference available on high speed boat design for someone with a technical background. https://www.amazon.com/Performance-Design-Hydrodynamics-High-Speed-Vessels/dp/0989083713

    Not for nothing and without any insult intended, but you're have no where near anything close to the technical understanding, necessary for this seemingly simple project.

    There are plans for these types of boats in various lengths, beams and speed ranges, literally hundreds of them. You'd be best advised to purchase a set of plans and have a go at it, make subtle stylistic and aesthetic changes as you like. The other option is a reasonable study of basic engineering and hydrodynamic principles, which would take considerably longer.

    Tea Floss, you have almost surely gotten the cart before the horse. You have begun by stating what you want the boat to look like or at least what the sections will resemble along with your predetermined dimensions.

    You want shallow draft, and 40 MPH. You can have both of those things but not necessarily with the sections you describe. First; how much power do you intend to put on the boat. That kinda' influences how fast you might go. How much of a load do you anticipate.....that is to say how many passengers, retriever dogs, and all the rest of the weight that the boat will carry, is this to be so shallow draft boat such as a "flats boat' that will function in only ten or twelve inches of water .....or are the duck blinds in deeper areas? What is likely to be the state of the water that you will operating in? Lakes, streams, the Gulf of Tonkin? . There are a lot of requirements that must be listed before you can design to satisfy those numerous requirements.

    Make a careful list of all the things that you want the boat to be capable of. That is called an SOR......or statement of requirements. Only then some of our members might be able to aim you in the most favorable direction.

    Most of the pros and old timers here will tell you buy a set of proven plans that has already shown the worth of the boat. I join them with that advice.

    As for Robb Whites boat: Rescue Minor, it is everything he said it is and does. I have been aboard that boat and have also seen it running in water almost as thin as wet pavement. A remarkable little boat it is/was. Sadly Robb white is no longer with us. RIP Robb.
