How do you decide if your small water craft is stable?

    Hello all,

    My question is about stability calculations for a small watercraft.
    Which calculations do you make and which rules you look for when you carry out stability calculation for your own design?

    Any method to follow? Or any recommended software(with the theory of the used method)?

    Thanks in advance and have a great day.

    Do you mean something like a canoe?

    Hi Furkan,
    I presume that you have designed a small water craft and you now want to calculate the stability for it.
    If so, can you post more details about the boat please?
    Are you familiar with stability calculations? Do you know the basic formula BM = I / V ?
    Where BM is the distance from the vertical centre of buoyancy to the metacentre, I is the second moment of area of the waterplane, and V is the volume of displacement at this waterplane.
