LUMPASAURUS - Custom Line FOR SALE

LUMPASAURUS, a 2023 Custom Line Navetta 33 luxury motor yacht, is offered in immaculate condition. A dedicated full-time crew has upheld rigorous standards with an emphasis on proactive care and ongoing enhancements, presenting a genuinely turnkey superyacht.

Across 2026, the yacht benefited from a comprehensive program of preventive servicing, mechanical attention, and cosmetic refinement, with the current owner investing over $400,000. Following a thorough pre-purchase survey and sea trial, the seller proactively resolved every observation noted by the surveyor, further elevating a vessel that was already maintained at an exceptional level.

US duty is paid, and the yacht has seen private use only—never chartered. Currently berthed at Island Gardens Marina in Miami, LUMPASAURUS is available for immediate inspection, and she carries MAN GSP Gold Standard Premium Extended Warranty and Seakeeper Platinum Extended Warranty through the end of March 2028.

Measuring 108 ft LOA, LUMPASAURUS delivers the volume and poise of a tri-deck superyacht, featuring five guest staterooms served by six guest heads, plus four crew cabins to ensure seamless service. Performance is provided by twin MAN V12 engines rated at 1,400 hp each, underscoring her Navetta-class pedigree as a long-range cruising yacht that blends comfort, stability, and elegance for discerning owners.

Main deck

A wide-body master suite set forward defines the main deck, where a custom office desk accompanies a custom leather bed frame and headboard against a striking wallpaper feature wall above the bed. An interior master walk-in closet with a lacquered finish and reading lights with a brass finish elevate the ambiance, while the master bathroom features built-in wash basins and a bench shower in exquisite Calacatta Oro marble. American walnut flooring flows through the salon, lobby, day head, and master cabin, unifying the spaces with warmth and sophistication. Daily life moves effortlessly thanks to an automatic opening door between the salon and pantry and an automated opening for the aft glass door in the main-deck salon, which also enjoys the allure of a balcony set into the starboard-side bulwark. The main-deck salon is appointed with a custom dining table by Paolo Castelli, a refined freestanding furniture package, and a tailored rug, while outdoors a custom main-deck cockpit furniture package is complemented by a coordinating rug and lanterns to complete the scene.

Lower deck

On the lower deck, four guest cabins provide refined accommodation. The starboard-side guest cabin includes a Pullman bed, and the portside and starboard VIP cabins feature separable, manual-sliding queen beds; in the starboard guest cabins an additional mattress fits between the beds for added versatility. Every lower-deck cabin is appointed with custom leather ottomans and mattresses specified beyond the standard, while curtains in all four cabins are raised electrically. The lower-deck cabin TV frames are finished in the same leather as the columns for a cohesive aesthetic. Bathrooms throughout the lower deck present Calacatta Oro marble washbasin tops, shower floors, and benches over American walnut flooring, with inspection hatches in the VIP showers, a mosquito net package for the portholes, and custom bathroom accessories with satin-finish taps and fittings.

Upper deck

The upper-deck salon showcases a freestanding furniture package enhanced by an additional ottoman, a rug, and American walnut flooring, anchored by a 55-inch Samsung TV in the upper salon, while the curtains are electrically raised for effortless ambiance control. A custom upper-deck cockpit furniture package complements a dining table with chairs, a sofa, and a coffee table, and the bar furniture features an additional refrigerator in the upper-deck cockpit along with an icemaker in the upper-deck bar. Connectivity is elevated with additional access points and Wi‑Fi infrastructure throughout the yacht, and a captain’s cabin is thoughtfully positioned next to the helm.

Sun deck

The sun deck is conceived for effortless indulgence, beginning with a Bimini top on the aft sun deck supported by sleek carbon fibre poles, complemented by a removable Bimini on the aft upper deck and a manual Bimini that shades the forward dinette to perfection. Kettal sunbeds invite lingering afternoons alongside custom stools and additional sun deck furniture packages, while a refined furniture module integrates a hydromassage bath tub with heater for restorative open-air relaxation. Underfoot, the sun deck and forward triangle area are finished in teak with black caulking, enhanced by a plush rug that softens each step. Evening ambiance glows with three Roda lanterns and exterior dimmer lights, while entertainment unfolds with a 49-inch TV on a lift-and-rotation system and invigorated sound from additional exterior loudspeakers. Practicality is woven into the luxury with an additional compressed-air outlet and an additional fresh-water outlet, and safety remains front and center with a dedicated position for liferafts at the aft.

Beach club / swim platform / garage

Purpose-built for effortless waterside living, the beach club, swim platform, and garages blend utility with refinement. A hydraulic/electrohydraulic aft garage system streamlines hauling and launching of the jet ski, while the layout accommodates customer tender installation with ease. In the bow garage, a crane with a maximum loading of 500 kg partners with a waterproof 220V socket to support seamless operations. The aft garage adds thoughtful touches, including a fresh-water outlet for washing, a waterproof roller curtain, and a backlit boat name that creates a striking signature. On the swimming platform, retractable cleats preserve clean lines, complemented by a removable side ladder and a hand shower delivering hot and cold fresh water on the bathing platform. After dusk, underwater lighting—four on each side and two aft—casts a dramatic glow across the water, and additional loudspeakers in the beach area elevate the atmosphere for unforgettable moments by the sea.

Helm / navigation

At the helm, a super premium integrated bridge upgrade anchors a suite of professional navigation and control technologies. A Furuno Class B Automatic Identification System (AIS) safeguards situational awareness, while a dedicated camera for night and low-light conditions extends vision, with the camera feeds repeated on the captain’s cabin TV. Gyro stabilizers refine the ride, and a 58 hp hydraulic stern thruster with a double propeller delivers precise, confident maneuvering. Everyday convenience is elevated by internal USB sockets in the cabins, the MD and UD salons, and at the helm, with US sockets thoughtfully located alongside European sockets. Connectivity is equally comprehensive, pairing a KVH HD11 antenna with a receiver in the salon and a Super Premium Internet package, together with a Starlink predisposition for seamless future integration.

Galley / pantry

An Ernestomeda galley anchors the culinary space, elevated by a Miele appliances upgrade and supported by custom fridges and a dedicated freezer in the galley, while a Miele washer and dryer deliver effortless utility. The upper-deck pantry enhances service with a Dunavox 181-bottle wine cooler, and seamless circulation is ensured by an automatic opening door between the salon and pantry. Pristine water quality is assured by an active carbon filter, a water softener, and a UV sterilizer for drinkable water, while extended autonomy at sea comes from an Idromar 500 l/h watermaker upgrade working in concert with a Hamann black-water treatment system.

Engine room / technical

Power is delivered by twin MAN V12 engines producing 1,400 hp each, with 2,015 hours recorded per engine. Electrical autonomy comes from Kohler main and auxiliary gensets, 55 kW, showing 3,000 generator hours and supported by an automatic parallel system among the gensets. Serviceability is streamlined by a centralized oil-change system serving the engines, inverters, and generators, while a 50 Hz frequency converter broadens shore-power compatibility. Fuel quality is safeguarded by an Alfa Laval fuel oil filter, and drivetrain reliability is enhanced by an Idrostop system for shaft line seals. The engine room is thoughtfully detailed with additional compressed-air and fresh-water outlets, genset ball valves, and clear stickers indicating pipe flow direction. Long-range independence is optimized with a duplex watermaker featuring an automatic washing system. Onboard comfort is assured by the “Comfort” Tropical air-conditioning package with UTA upgrade, and seakeeping is elevated by gyro stabilizers.
