The clients who commissioned this power yacht design are a retired couple in the Chesapeake Bay area of the U.S.A. They live aboard their boat and cruise the Bay and the Intracoastal Waterway on the East Coast.

The style of the hull is traditional eliptical stern tug above the waterline combined with a trawler-yacht underbody of much lighter displacement than would be found on a working tug. The superstructure is a blend of a traditional tug pilothouse with a deckhouse needed for the accommodation.

Hull and deck construction is steel using a radiused single chine hull form while the superstructure is aluminum. The junction between the two metals is either bolted, with isolation material, or welded, with a bi-metallic bonding strip. Both the hull and superstructure are longitudinally framed, i.e. the shell plating is supported by longitudinal stringers which are in turn supported by widely spaced frames. This permits simpler construction than transverse framing and presents less fairing problems.

As from July 2008, we now also have drawings to build this design from wood throughout. The hull is bead and cove strip plank western red cedar, with plywood decks and superstructure.
