    Would anybody have the lines or offsets or a CAD model of a Charles Wittholz 'Departure' hull and keel that they could email to me?

    It's for a keel alteration (I'm changing it to a deeper fin keel for the client) and initially I need just need enough to define an accurate outer surface, so that I can model the stability and tie it to an inclining test prior to re-ballasting.

    This one has a full keel and draws around 5 feet.

    Cheers

    I have always liked that boat . I wonder if it be worth it to build one today?
    Seams like the perfect all around boat .

    Charlie produced several developments of the Departure 35 in sizes from 27 to 35 feet.
    I believe they were all built in steel/aluminium.
    He owned one himself called Good Omen.

    There are plans for wood and scantings for plywood . I believe that they were produced in wood by a yard in Maryland .

    Certainly for the Departure 35, but I don't think plans were done for the other sizes in anything other than metal. In later life, Charlie had a very bad experience with a LPG fire on a boat and become a staunch advocate of metal hulls (and LNG for cooking), and his plans reflected this.

    Thanks for your responses.
    The owner is quite experienced, he likes his boat but he would like better maneuverability and a less leeway to windward. Apparently there are plans for 4 and 5 foot draft versions.

    I was told the wooden lines varied a little to the steel. So I'm not sure how useful the wooden version lines are.

    Interesting history, where did Charles start his career, it was under another well known designer was it Alden?

    cheers

    If I remember right, he worked for Phil Rhodes (drew the lines for the Dyer Dhow there), but not sure about Alden.

    But before that he was time served at a larger shipyard.

    The steel version is about 7" wider to compensate for the greater weight of the steel.
    10'5" verse 11'0" .

    Thanks Frank

    And probably 5 feet of draft in the steel version rather than 4'3" But the lines will be close. It's quite a common design but the plans for steel seem to have faded away. Only the timber plans appear to be available.

    Do you have any other data ?

    Yes, it was Rhodes I was thinking of not Alden.

V-bottomed chine boat ... ... somewhat boxy look ... ... [+ many good things mentioned] ... ... outside ballasted keel ... ... lead or iron ... ... there are plans for an aft cabin and inboard rudder ...

    Good Luck!
