Nautilus - Leopard Catamarans FOR SALE

“Nautilus” is a Leopard 53 power catamaran that stands out as an exceptional liveaboard cruising platform, arguably the finest of its kind on the market. Carefully refined by seasoned owners, she benefits from a thoughtful suite of enhancements that elevate comfort, autonomy, and ease of operation while preserving the brand’s hallmark elegance and seaworthy temperament.

Beyond essential self-sufficiency features such as a robust watermaker and a full-size dishwasher, the boat is sprinkled with smart comforts you’ll notice every day: custom bug screens for every porthole and door, an added freezer for extended provisioning, a bespoke boarding ladder, an extra touchscreen display where you want it most, and a high-capacity lithium battery bank paired with dual DC‑DC chargers that dramatically increases usable power, trims roughly 500 pounds of weight, and streamlines life at anchor.

The 53 delivers expansive volume, a shallower draft, and notably efficient fuel burn compared with similar offerings. Dependable Yanmar diesels on preferred straight shafts make this a standout owner‑operator motor yacht for exploration and coastal or bluewater passages. Impeccably maintained and dialed-in, she is presented in true turn‑key condition—step aboard and cast off.

On deck, a custom Eisenglass flybridge enclosure teams with SeaDek throughout the cockpit, side decks, foredeck, and upper levels for comfort underfoot and a refined, modern look. Maneuvering is made effortless with a new Dockmate Twist wireless control that adds joystick handling plus remote control of the anchor, bow thruster, and horn, while custom stainless rub rails protect during tight dockings. Reliable connectivity comes via Starlink integrated with a Pepwave router, and the bow thruster adds confident close-quarters control. The STW800 watermaker, dishwasher, extra freezer, and a forepeak crew berth with its own head underscore true long-range cruising capability, and twin Sonihull ultrasonic antifouling units help keep the hulls clean with minimal fuss. Custom covers protect all exterior seating and the flybridge console when not in use.

The tender package leaves nothing to be desired: a 13' Highfield 380 with a 30 hp Suzuki, bench seating, wheel steering, navigation gear, and matching SeaDek is ready for shore runs and exploring. Power management is first-rate with four new 280‑Ah lithium batteries, two DC‑DC chargers, and twin Victron MultiPlus 2 inverter/chargers. Helm stations are upgraded with twin 12" Axiom touch displays at the lower helm and twin 16" screens above, complemented by sun awnings shading both the upper deck and cockpit. Entertaining is effortless thanks to an electric grill, icemaker, and refrigerator on the flybridge; entertainment continues below with 50" and 40" flat-screen TVs and motion-sensor cabin lighting. After dark, six SeaBlaze underwater lights orchestrated by a Poco controller create a dramatic glow at anchor. Ground tackle is premium, featuring a polished stainless Ultra 100‑lb anchor with Ultra swivel and a Mantas chain claw, supported by a BRNKL security system for peace of mind. An upgraded 11‑gallon water heater, six rod holders, and a portable washer/dryer round out a specification tailored for extended time aboard.

As a luxury power catamaran and flybridge cruising catamaran, this multihull motor yacht embodies the ideal liveaboard, bluewater‑ready, owner‑operator platform—stable, efficient, and beautifully appointed. “Nautilus” is making her way north to Martha’s Vineyard for the summer and will be available to view by appointment.

Construction

Engineered for strength and quiet performance, the hull is a resin‑infused layup over a foam core, and the decks are GRP with the same resin‑infused foam‑core construction for stiffness and weight savings. A spade rudder arrangement provides crisp handling, the catamaran underbody delivers stability and efficiency underway, and the build pedigree traces to Cape Town, a renowned hub of composite yacht craftsmanship.

Engines and controls

Twin engines are set port and starboard and drive straight‑shaft gearboxes for direct, efficient thrust. Command inputs are precise through Yanmar electric controls, and reliability offshore is enhanced by freshwater heat‑exchanger cooling for both propulsion plants.

Navigation & electronics

Situational awareness is complete with forward and aft cameras, a Raymarine AIS transceiver, and a Raymarine autopilot working in concert with Raymarine Axiom displays—twin 16‑inch screens at the upper helm and twin 12‑inch at the lower station—while compasses serve both the flybridge and the interior helm. A Fusion marine stereo with speakers throughout, plus USB and Bluetooth connectivity, fills every space with sound. A digital switching system streamlines control, and onboard safety is strengthened by CO detectors and a propane sniffer.

Inside equipment

Life aboard is thoughtfully appointed: fans in all cabins pair with climate control, and twin fresh‑water pumps ensure steady pressure. The gourmet galley centers on a Miele four‑burner stove, a full‑size Samsung refrigerator with purification system, an extra freezer drawer, a GE Profile microwave, and a Fisher & Paykel dishwasher. The flybridge features a Kenyon electric grill and a single‑basin stainless‑steel sink; matching single basins serve the galley, with single hand basins in guest heads and dual basins in the master. Bathing is a pleasure with three interior showers plus a hot‑and‑cold cockpit shower.

Electrical equipment

The yacht runs a 120‑volt system on a 50 amp electrical circuit, backed by four new 280 A/H lithium house batteries, one dedicated engine battery per side, and a single generator battery. Inversion and charging are handled by two Victron Phoenix 12/3000 units and one Victron Phoenix 12/1200, plus a Victron Centaur 12/100 battery charger, while ship’s power is assured by a 12 kW Northern Lights generator showing 900 hours.

Deck equipment

Handling is confident with a Sea Star hydraulic steering system and a Lewmar windlass serving serious ground tackle: a stainless‑steel Ultra 100 lbs primary anchor on an Ultra swivel with a Mantus chain claw, complemented by a Delta secondary. The cockpit can be enclosed in white Sunbrella, and comfort is elevated by a Kenyon electric grill, Vitrifrigo icemaker on the flybridge and a Samsung icemaker in the galley, plus a well‑appointed flybridge wetbar with single sink, Kenyon grill, icemaker, Vitrifrigo refrigerator, organized storage, a fire extinguisher, and a waste bin. Launch and explore with a Highfield CL380 Hypalon dinghy powered by a 30 hp Suzuki four‑stroke, keep the yacht secure with six fenders, and relax on upgraded teak cockpit tables, with SeaDek underfoot on cockpit and sidedecks. A cockpit shower and a swimming ladder make water access inviting.

The tender package is exemplary: a Highfield CL380 with FCT steering system, custom SeaDek flooring, VHF, saddle bags, boat cover, anchor, and ratchet straps, driven by a Suzuki 30 hp four‑stroke outboard with a custom cover. Ground tackle is upgraded to an SS Ultra 100 lb anchor on an Ultra swivel with a Mantus chain claw.
