    Formulas

    When the boat is not in a foilborne condition traditional formulas for displacement hulls apply.

    Hi!

    I am a naval architect student and I am doing a project on hydrofoils too.

    I am searching for a long time through the internet, but I have not found any technical drawings for Hydrofoils.

    It is easier to find drawings for bulk carriers, tankers, etc, but not for Hydrofoils.

    Formulas

    When operating in the displacement condition, a hydrofoil craft IS a conventional ship.

    When foilborne, hull shape and displacement can be ignored. You only need to find how much hydrofoil surface you need to support a given weight and where to locate the hydrofoils in relation to the craft's center of gravity.

    Hard to believe, but not all knowledge is avaliable through the internet. Yet.

    Try the AMV CD's from IHS at foils.org. You'll find whole multi-volume Navy design manuals for the specification and design of hydrofoils.

    I have just started too!

    I am doing the theoritixal part of the project for the time.

    Later on, I might start designing a hydrofoil boat.

    But I am not sure yet.

    You are partly right.

    I order to get the sip foilborne easy and quickly, the hull lines must be appropriate.

    Also, when foilborne,you have to consider that the hull must have the right shape, so that you won;t have problems with the waves when the sea is rough.

    Rough Seas

    When the seas get rough enough for that to be a consideration, if a boat is still foilborne it's probably going too fast for the conditions in the first place.
