    Do you know the hull drag at design speed?

    Have you decided on a gear ratio?

    Have you a preferred cadence?

    Do you know how much power you want design for - how many people, how fit, male or female etc?

    Easier to make from steel than wood. You should be able to make one in about 6 hours.

    If you provide the above information or enough to allow me to work it out I will give you a prop design.
