By Elizabeth Ginns Britten A full-beam master on a yacht in the 120-foot size range is common. But this on-deck one features pocket doors leading to a luxurious marble bath. The formal saloon and adjoining dining area were designed by Roberto Lottini and showcase luxurious Italian touches. There's a gorgeous etched-glass dining table and the china cabinet in the dining area. The casual country kitchen should appeal to American buyers. The kids will dig this twin-bed guest stateroom on the lower deck. Those big ports are about two feet tall. High-end touches abound in the VIP head, which features a full soaking tub and another large port. Crew quarters on the 120 are forward, which helps free up space in the lazarette for a practical, commercial-style laundry center.
