The hull lines are based on a traditional long keel configuration with a cut away forefoot, wineglass mid-ship sections and an attached rudder. The upper half of the balanced rudder is attached to the keel; the lower part is designed to breakaway in case of severe impact. The propeller is located on centerline in an aperture and forward of the leading edge of the rudder. The deck plan has a large cockpit at deck level located between two deckhouses. The forward half is arranged for lounging and dining and allow for easy access to the forward sunken deck house, the aft part is set up as a helmsman station with good all around visibility and with direct access to the sunken aft deck house, which is the chart house. The side decks are kept wide and uncluttered by locating all the deck structures, such as the cathedral salon skylight, skylights, hatches and stowage boxes, close to centerline.
