    DuckSkiff

    Duckskiff is a 14 foot skiff I designed for a buddy of mine named Tim that I work

    with. Tim is an avid Duck hunter and wanted a fairly lightweight boat but in nice quiet

    wood rather than noisy aluminum. He also wanted something a little boatier than a

    Johnboat styled craft. What I came up with for him is a 14 ft long 5 ft wide at the shear

    (45 inches wide at the bottom) kind of semi-dory hull. I did this to make it an easier anddryer proposition when pulling a large dog over the side and back into the boat. The

    additional ultimate stability of the 23 flare to the sides allows a lot of weight to be right

    at the sides of the boat while at the same time getting the shear lower to the water. He

    wanted to be able to use his 7 hp motor to get around now with the probability of

    upgrading to a higher hp later on. As the hull was originally derived from a rowing style

    hull I was playing with a few months previously I tweaked both of them so that they were

    brother and sister similar and decided to present them to you here. Enjoy

    LOA: 14 3
