Overview and Design Philosophy
The Doge 350 belongs to Ocean King's esteemed Doge series, a line defined by explorer-yacht DNA —the marriage of commercial shipbuilding heritage with contemporary superyacht design standards. Measuring 114 feet overall with a beam of 27.2 feet and a full-load draft of 7.5 feet, the vessel displaces 330 tons at full load, providing the mass and stability required for comfortable ocean passage-making. The hull is constructed from steel with an aluminum superstructure, a configuration that delivers the durability and longevity essential for expedition cruising while maintaining reasonable weight distribution and fuel efficiency. The Doge 350 carries RINA C + HULL and MACH Y class notation, certifying unrestricted ocean navigation. This classification underscores the yacht's engineering integrity and compliance with rigorous international standards for structural strength, stability, and seaworthiness—critical credentials for owners planning extended offshore passages. The vessel's external design is by Design ALOT, while interior architecture is handled by Margini Architects, ensuring a cohesive aesthetic from deck to cabin. Engineering is by InNave, a firm specializing in explorer and expedition yacht systems integration. This collaborative design team approach reflects Ocean King's commitment to balancing rugged functionality with refined living spaces.
Hull Design and Seaworthiness
The Doge 350 employs a full-displacement hull form with a bow bulb, a design philosophy optimized for fuel efficiency and sea-keeping comfort at cruising speeds rather than high-speed performance. Full-displacement hulls are characterized by their ability to move through water with minimal dynamic lift, resulting in stable motion, predictable handling, and excellent fuel economy—qualities that directly extend range and reduce operational fatigue during extended voyages. The bow bulb further enhances hydrodynamic efficiency by reducing wave-making resistance and improving the vessel's motion in head seas. This design choice reflects Ocean King's commercial shipbuilding heritage; bulbous bows are standard on cargo vessels and offshore support ships precisely because they deliver measurable improvements in fuel consumption and seaworthiness. The steel hull construction provides superior impact resistance, longevity, and structural integrity compared to composite or aluminum hulls. Steel's strength-to-weight ratio and resistance to UV degradation, osmotic blistering, and impact damage make it the preferred material for vessels intended for extended cruising in remote regions where repair facilities are limited. The aluminum superstructure keeps the center of gravity lower than an all-steel construction, improving stability and reducing fuel consumption.
Propulsion, Power, and Performance
The Doge 350 is powered by twin MAN V8 800-horsepower diesel engines paired with Reintjes WAF 264 LP gearboxes. This propulsion package delivers a maximum speed of 14.5 knots and a cruising speed of 12.5 knots, performance figures aligned with the full-displacement hull's design envelope. The engines drive through direct shaft lines with flexible Vulkan ProFlex couplings to optimize vibration isolation and comfort. The propellers are specified in NiBrAl class "S" with five blades and a diameter of 1,400 millimeters, engineered to balance thrust efficiency with noise and vibration reduction—a critical consideration on a yacht designed for extended cruising where operational quietness enhances the onboard experience. The shafts are constructed from Mariox 17, a duplex stainless steel that resists corrosion in saltwater environments. Rudders are AISI 316 stainless steel, further ensuring corrosion resistance and long service life. At a 10-knot cruising speed, the Doge 350 achieves a range of 5,000 nautical miles, providing the endurance required for transoceanic passages without requiring fuel stops at every port. This range, combined with a fuel capacity of 11,889 gallons (45,000 liters), makes the yacht capable of voyages across the Atlantic, through the Mediterranean , or across the Pacific with strategic refueling stops. An engine upgrade option is available, offering twin MAN V8 1,200-horsepower engines for buyers prioritizing higher speeds or improved acceleration. Selecting this upgrade would increase maximum speed and enhance the vessel's ability to depart marginal weather windows, though it would increase fuel consumption and reduce range compared to the standard 800-horsepower configuration.
Electrical Generation and Power Management
Two 80-kilowatt 50-hertz diesel generators provide electrical power for hotel loads, air conditioning, and auxiliary systems. This redundancy ensures that loss of a single generator does not compromise critical systems or comfort. The generators are sized to supply 420,000 BTU/hour of air conditioning capacity, adequate for maintaining comfortable interior temperatures in tropical and subtropical climates during extended anchorages. The fresh water capacity of 2,642 gallons (10,000 liters) supports extended periods away from port. Combined with the swim pool water tank capacity of 2,113 gallons (8,000 liters), the yacht carries substantial water reserves for crew and guest use, reducing the frequency of water stops and enhancing self-sufficiency during remote cruising.
Accommodations and Interior Layout
The Doge 350 accommodates up to 10 guests across five staterooms and provides crew quarters for up to six crew members in three to four cabins. Seven heads (marine bathrooms) serve both guest and crew areas, ensuring adequate facilities for extended voyages with a full complement of people onboard. The five guest staterooms are designed by Margini Architects and are described as beautifully appointed, suggesting a focus on refined finishes, natural lighting, and comfortable furnishings rather than ostentatious decoration. The distribution of accommodations across five cabins provides flexibility for different cruising scenarios—whether hosting a smaller group of close friends or accommodating a larger party of family and guests. Crew quarters sized for six crew members reflect the operational reality of a 114-foot expedition yacht. A crew of this size supports 24-hour navigation, maintenance, provisioning, and guest services during extended voyages. The separation of crew accommodations from guest spaces maintains privacy and allows crew to rest and work without disrupting guest areas. The seven heads represent a generous ratio of facilities to occupants, reducing scheduling conflicts and enhancing comfort during extended cruising. Multiple heads distributed throughout the yacht minimize the impact of any single head being out of service and provide convenient access from various cabin areas.
Deck Layout and Tender Garage
The Doge 350 features a tender garage capable of stowing a 5.65-meter diesel jet tender. This integrated garage design protects the tender from weather and UV exposure while maintaining a clean exterior appearance. A diesel jet tender, as opposed to a gasoline-powered outboard boat, offers advantages in range, refueling compatibility with the yacht's fuel system, and reduced fire risk—practical considerations for expedition cruising where support vessels may be deployed for extended periods away from the mother ship. The deck layout, while not detailed in the available specifications, would be organized to support the yacht's expedition mission, likely including protected outdoor areas for observation and wildlife viewing, secure railings and handholds for safe movement in heavy weather, and storage for diving equipment, fishing gear, or other recreational equipment appropriate to the cruising region.
