    Converting a John Hacker "Doodlebug" to row boat

    SORRY MY MISTAKE _ ITS DOODLEBUG NOY SLIPPERY

    I have plans for a John Hacker 12 foot V hull "Slippery" ( from Motorboating Book Volume 24). I'm totally enthralled by the hull design and would like to convert this for rowing. Keeping the length as it is, the beam at 59 inches seems to be too great for oars. My idea was to lay the frame lines , then from the center line deduct 5 inches from either side. This way I would end up with the same 12 foot profile and beam of 49 inches.

    Suggestions appreciated
    Thanks

    Is this boat you have plans for, a planing hull, I assume yes ? That is not a sound basis for a row-boat, unless you want to work up a sweat and be going nowhere fast.

    Its a V shaped and looks like fat pram with its flat front end.

    John Hacker's "Slippery" is a class 135 hydroplane. It does not have a flat bow and requires a lot more power to plane than what a human can generate. That design is a really, really bad choice for a rowboat.

    Can the OP possibly mean the Hacker Slippery that a web search brings up?

    That is about as far from a human powered boat as can be imagined at that length.

    The squared bow makes it look like a pram, but the aft end is that of a planing hull, and not suitable as a row-boat, but you could easily make something that looks similar above the waterline, that can be rowed easily enough.

    OK, I think I see what you mean. I have an other set of plans here by Edwin Monk -"Stubby". Yes theres a big difference. Think maybe I will go with this but space the frames apart 20" instead of the 18" - this will give me 10 foot craft.

    Gosh theres so much to learn
