Ocean King Doge 350: A 114-Foot Steel-Hulled Explorer Yacht for Long-Range Cruising and Expedition Voyages
The Ocean King Doge 350 represents a distinctive approach to modern superyacht design—one that prioritizes seaworthiness, range, and operational resilience without sacrificing the comfort and refinement expected of a luxury vessel. At 114 feet overall length (34.75 meters), this full-displacement steel-hulled explorer yacht is engineered for serious long-range cruising, capable of undertaking extended voyages across open ocean while maintaining the stability and living standards that distinguish a true expedition yacht from conventional motor yachts.
Overview: Purpose-Built for Extended Voyaging
Built by Ocean King Yachts, a shipyard based in Chioggia within the Venice lagoon and drawing on over 35 years of commercial steel vessel construction, the Doge 350 exemplifies the builder's philosophy of merging explorer DNA with luxury accommodations. The vessel's hull is constructed from steel with an aluminum superstructure, a combination that delivers the durability and corrosion resistance required for remote cruising while optimizing weight distribution and structural integrity. The Doge 350 carries RINA C + HULL class notation with MACH Y unrestricted navigation certification, confirming that the vessel meets international standards for unlimited ocean service. This classification reflects the yacht's full-displacement hull form with integrated bow bulb, a design that prioritizes seaworthiness and fuel efficiency over speed, enabling the yacht to maintain a comfortable 12.5-knot cruising speed while achieving a 5,000-nautical-mile range at 10 knots—a capability that opens genuine long-distance cruising possibilities. The 2028 Doge 350 is available as a spec build, allowing future owners to customize accommodations, interior finishes, materials, and onboard systems to align with personal preferences and intended use. This flexibility distinguishes the vessel from completed inventory models, offering the opportunity to shape the yacht's final configuration before delivery.
Accommodations: Five Staterooms, Seven Heads, and Crew Quarters
The Doge 350 is arranged to accommodate up to 10 guests across five staterooms, with separate crew quarters capable of housing up to six crew members. This layout reflects the yacht's design brief as a long-range cruising platform suitable for extended voyages with family, guests, or charter operations, where comfortable, private accommodations and dedicated crew spaces support both guest experience and operational efficiency. The vessel includes seven heads distributed throughout the accommodation spaces, ensuring that guest staterooms and crew quarters maintain independent facilities. This level of sanitary provision is essential for vessels undertaking extended passages where comfort and privacy directly influence passenger satisfaction and crew morale during weeks or months at sea. The interior design is led by Margini Architects, while external styling comes from Design ALOT, both firms with experience in explorer and expedition yacht aesthetics. The 2028 build year indicates that the vessel incorporates contemporary design thinking while maintaining the timeless proportions and functional layouts that characterize successful long-range cruising yachts.
Power and Propulsion: Twin MAN Engines with Extended Range
The Doge 350 is powered by twin MAN V8 800-horsepower diesel engines, each connected to a Reintjes WAF 264 L gearbox via direct shaft lines with Vulkan ProFlex flexible couplings. The propulsion system drives NiBrAl 5-bladed propellers (1.4-meter diameter) specifically designed to optimize comfort and efficiency—a refinement that reflects the builder's focus on minimizing vibration and noise during extended cruising. The dual-engine configuration provides redundancy critical to ocean-going vessels, ensuring that the yacht can maintain steerage and progress toward port or assistance should one engine require servicing or repair. The shafts are constructed from Mariox 17 stainless steel, while the rudders are AISI 316 stainless steel, materials selected for resistance to corrosion in saltwater environments. Maximum speed is rated at 14.5 knots, with a comfortable cruising speed of 12.5 knots. The fuel tank capacity of 11,889 gallons (45,000 liters) combined with the efficient full-displacement hull form enables the 5,000-nautical-mile range at 10-knot cruise speed. For owners planning extended voyages to remote regions—the Caribbean , Mediterranean , South Pacific, or polar waters—this range eliminates the need for frequent fuel stops and expands the geographic scope of practical cruising. An engine upgrade option is available, offering twin MAN V8 1,200-horsepower engines for owners seeking higher performance, though this upgrade would reduce fuel efficiency and alter the yacht's operating economics.
Power Generation and Onboard Systems
Two 80-kilowatt, 50-hertz diesel generators provide electrical power for hotel loads, air conditioning, and onboard systems. This dual-generator arrangement ensures continuous power generation even during routine maintenance and provides redundancy for extended cruising in remote locations where shore power is unavailable. The yacht's air-conditioning system is rated at 420,000 BTU/hour, sufficient to maintain comfortable interior temperatures in tropical and equatorial waters where extended cruising often occurs. The scale of this cooling capacity reflects the yacht's full-displacement design, which generates heat through engine operation and solar gain but benefits from the thermal mass and insulation provided by steel and aluminum construction. Fresh water capacity totals 2,642 gallons (10,000 liters), supported by a dedicated 2,113-gallon (8,000-liter) swim pool water tank—a feature that distinguishes luxury explorer yachts from purely functional vessels. Black and grey water tanks (1,849 gallons combined capacity) are sized to support five staterooms and crew quarters for extended periods between pump-out facilities.
Hull and Structural Design
The full-displacement hull with bow bulb represents a deliberate choice favoring seaworthiness and fuel efficiency over speed. This hull form minimizes wave-making resistance, allowing the yacht to maintain efficient cruising speeds across a range of sea states while delivering the stability and motion characteristics that long-range cruising demands. The bow bulb improves buoyancy forward, reducing pitching motion and enhancing comfort in head seas—a practical benefit during extended ocean passages. Steel hull construction provides several advantages for explorer yachts: superior durability in contact with ice, rocks, or rough anchorages; excellent corrosion resistance when properly maintained; structural strength that accommodates heavy equipment, extended range fuel tanks, and reinforced fittings required for remote cruising; and the thermal mass that aids climate control in extreme environments. The aluminum superstructure reduces top-weight, improving stability and fuel efficiency while maintaining the structural integrity required for open-ocean service. The 27.25-foot beam provides generous interior volume while remaining within practical limits for canal transits and port facilities frequented by superyachts.
Dimensions and Operational Characteristics
The Doge 350 measures 114 feet overall length, with a 109.8-foot length on the waterline. The maximum beam of 27.2 feet and draft of 7.5 feet at full load define the yacht's footprint in relation to port facilities, anchorage depths, and canal systems. At full load displacement of 330 tons, the yacht maintains excellent stability and sea-keeping characteristics while accommodating the fuel, water, provisions, and equipment necessary for extended voyages. The gross tonnage of 365 GT places the vessel above the threshold where certain regulatory exemptions apply, but the RINA C classification confirms compliance with international standards for passenger-carrying yachts and confirms the yacht's structural and operational integrity for ocean service.
Why This Yacht Deserves Consideration
The Ocean King Doge 350 appeals to experienced cruisers and expedition-minded owners who prioritize seaworthiness, range, and operational self-sufficiency over maximum speed or the latest styling trends. The vessel's steel construction, full-displacement hull, twin-engine redundancy, and 5,000-nautical-mile range position it as a genuine ocean-crossing platform capable of reaching remote destinations and maintaining comfort and safety across extended passages. The availability as a spec build offers the rare opportunity to shape the final yacht to match personal preferences in layout, finishes, and onboard systems before construction is completed. For owners planning extended voyages—whether circumnavigations, polar expeditions, or multi-year cruising programs—the Doge 350's proven design approach, builder reputation, and engineering fundamentals provide confidence in the vessel's ability to deliver adventure and comfort without compromise. The combination of five guest staterooms, dedicated crew quarters, seven heads, and comprehensive onboard systems supports both private ownership and charter operations, offering flexibility in how the yacht is ultimately utilized. The 2028 build year ensures that the vessel incorporates contemporary systems and materials while honoring the tim
