The deck house is aligned and tacked on with thickened epoxy. (My wife has changed her assessment of the project from "coffin" to "tug boat.") The house tapers to provide full width at the aft end and accomodation for yuloh storage at deck level forward.
Overhead view. The bracing was used to spread the house sides and the front and back to fit the deck. Still have to fit the side deck carlins now that the shape is established.
