    Photos and some drawings of a 56 foot steel passenger under construction at Washburn & Doughty in East Boothbay, Maine. The ferry will be used on a 1 1/2 mile route between Chebeague Island and Yarmouth, Maine.

    Washburn & Doughty uses straight frames in their vessels which results in many of the hull plates having compound curvature. They prefer needed to put compound curvature into plates over the complications of curved frames which would be required by single curvature developable surfaces.

    It is always about what can be built and how it is built. If that is not addressed by the designer/Naval Arch....it'll end in tears and depleted bank accounts.
    First rule of design, if you don't know how it is going to be built, how can you design it?

    Washburn & Doughty designs most of the vessels they build so the designs are optimized for their methods and capabilities. My guess is that has something to do with their having been in business for over 40 years, including surviving a major fire.
