This 1998 Hyatt 51 Aft Cabin Motor Yacht is a twin-diesel cruiser built on a modified V planing hull. Powered by twin Detroit Diesel 671 engines producing 485 horsepower each, she reaches a top speed of 21 knots and cruises efficiently at 15 knots. The fiberglass hull and cored deck construction provide durability, while the 51-foot length and nearly 16-foot beam deliver substantial volume for extended voyaging or liveaboard use.
The layout comprises two staterooms and two heads, sleeping six across a forward V-berth, aft master, and convertible dinette. The main salon features a starboard-side galley at salon level with solid wood cabinetry, a two-tub sink, electric stove, convection microwave, and refrigerator with freezer. The galley connects to the salon proper, which includes a dinette with adjustable table, port-side desk with storage and workspace, and wingback seating. Both the master and guest staterooms feature queen berths with under-bed storage and generous locker space. Each head is outfitted with an elevated electric flush toilet, Corian countertop sink, mirrored vanity, and shower with tub or separate shower enclosure.
All interior and exterior spaces are air-conditioned, including the enclosed aft deck and flybridge. The aft deck includes a wet bar with sink and ice maker, flat-screen television, and seating for six. The flybridge offers bench seating with in-seat storage and a single helm chair, all protected by a canvas enclosure. Exterior features include teak and holly sole in select areas, carpeting throughout main spaces, stainless steel rails and grab handles, and a swim platform with transom shower.
Systems include twin-disc transmissions, a 20 kW Northern Lights generator installed in 2021, hydraulic trim tabs and steering, and a fresh water system with two electric flush heads and macerator. Dual fuel tanks hold 600 gallons total. The electrical system features six AGM and two gel-cell batteries, a new Outback Power inverter/charger, and a new Victron 12V charger. Navigation electronics comprise two Garmin MFDs with GPS, chart plotter, sounder, and radar, plus a Standard Horizon VHF with AIS. Engine room details include oil change system, fire suppression, and four bilge pumps with float switches.
