Tankoa S501 49.9m Motor Yacht 2022 6 Cabins Lloyd’s Standard La Spezia Italy

Overview
Delivered in April 2022 by Tankoa Yachts, this 49.9-metre aluminium motor yacht is the fourth hull in the acclaimed S501 series (project name: Elettra). Built to Lloyd’s Register technical standards and registered under the flag of Saint Kitts and Nevis, she offers a near-new, class-compliant platform with modern semi-displacement performance, cohesive Italian styling, and excellent long-range credentials.

Design, Classification & Build Details
Naval architecture was developed in-house by Tankoa, while both exterior styling and interior design were created by Francesco Paszkowski Design in collaboration with Margherita Casprini—delivering a unified design language from profile to interior detailing. Her semi-displacement aluminium hull and aluminium superstructure are finished in classic white with teak-laid decks across three expansive levels.
Key dimensions include 49.9m LOA, 49.4m LWL, a generous 9.45m beam, and 3.0m draft. She measures 496 GT with a displacement of approximately 418 tonnes. Construction started late 2019, launching occurred in March 2022, and delivery followed in April 2022 after comprehensive sea trials. A distinctive vertical bow increases internal volume and supports confident seakeeping, reinforcing her long-range, multi-region cruising intent.

Propulsion, Efficiency & Range
Powered by twin Caterpillar C32 diesel-electric engines as specified (1,319 hp / 1,769 kW each; 2,638 hp / 3,538 kW combined), she drives twin screw propellers through a robust shaft propulsion system engineered for durability and efficiency. Performance targets an owner-friendly balance: 17 knots maximum, 14 knots cruising, and 12 knots for economical passages.
At 12 knots she delivers an impressive approximate 4,700 nautical mile range. Fuel capacity is 56,100 litres and freshwater capacity is 21,340 litres, providing strong autonomy for extended cruising programs.

Handling, Stabilization & Systems
A bow thruster supports close-quarters manoeuvring, while stabilizers operate both underway and at anchor to reduce roll and maintain guest comfort. The engine room emphasizes accessibility and service efficiency, with visible serial plates, organized cooling circuits, fuel filtration systems, engineered exhaust routing, and resilient mounts to minimize vibration transmission.
Electrical systems include generator capacity dedicated to hotel loads, battery banks, distribution panels, breakers, inverter and charger units, and shore power connectivity for seamless dockside integration. Plumbing and onboard infrastructure include pressurized freshwater pumps, bilge pump arrays, hot water systems, grey/black water holding tanks, and advanced waste management. Fire suppression in machinery spaces, verified navigation instrumentation and safety equipment support full operational readiness. The aluminium hull below the waterline carries professional antifouling protection, and underwater appendages are engineered for reliability and serviceability.

Guest & Crew Accommodation
Guest accommodation is arranged for 12 guests in 6 cabins, supported by 9 crew in 5 crew cabins plus a dedicated captain’s cabin—an efficient and discreet service structure for private cruising or charter-style operations. The main deck master suite is positioned for privacy and prestige with a king-size bed, walk-in wardrobe and a spacious en suite featuring dual vanities and a substantial rain shower.
A VIP suite and additional guest cabins maintain refined comfort and consistent styling throughout. Interior finishes include brushed oak flooring, lacquered light ceilings, and leather wall panels in graduated grey tones, with bespoke detailing and extensive glazing to flood the interior with natural light.

Interior Living & Entertaining Spaces
The main salon is fitted with notable furniture selections (including Minotti and Gallotti & Radice) and flows naturally into a formal dining area adjacent to a well-equipped galley designed for efficient crew circulation. The result is a layout that supports both high-end hospitality and practical day-to-day ownership use.

Exterior Lifestyle: Pool, Beach Club & Deck Flow
Exterior amenities are a standout in this size class. Forward, a 5,000-litre swimming pool creates a resort-style social zone with surrounding seating and tables. A beach club integrates gym access and a day head, while the transformer-style bathing platform—reached via twin staircases—provides a proper sea-level terrace experience. The sundeck offers sunpads, an outdoor galley, pop-up tables and shaded lounge areas beneath the radar mast canopy. Further features include a deck Jacuzzi, hammam, exterior bar, winter garden, BBQ, underwater lights, outdoor cinema capability, foredeck seating with table, swimming platform and full air conditioning throughout.

Connectivity & Entertainment
Satellite TV, Starlink and Wi-Fi systems support reliable onboard connectivity and entertainment for modern cruising expectations.

Tenders & Garage
Tenders include a 6.3m Castoldi 21 Jet Tender and a 4.28m Castoldi 14 RB SOLAS rescue boat, housed within a side-loading tender garage for clean deck lines and operational convenience, while also supporting safety compliance.
