Engine hours stand at 6,117 on port and 6,188 on starboard as of 29 September 2025, with the five-thousand-hour engine service completed at the end of 2023 and the starboard engine completely rebuilt in 2023/2024. Electrical generation comes from two 65 kW (87 hp) Onan diesel generators, showing 12,997 hours on port and 12,598 hours on starboard as of 29 September 2025, following a major twelve-thousand-hour service in 2025; the starboard generator wiring harness was also replaced in 2025.

Recent upgrades include new network access points and the installation of two dome‑less Starlink Maritime panels and one OneWeb Italian panel, bringing robust, modern bandwidth to the yacht.

Deck equipment is selected for reliability and ease of operation. Twin Maxwell 6000 anchor windlasses were overhauled in 2025, working with anchors that include a 210 kg Manson and a High Holding Kedge, both secured on chains of six shackles that were re‑galvanised in 2025. A pair of Maxwell aft warping capstans simplifies docking. Tenders and toys are launched by a Besenzoni crane with a safe working load of 560 kg, and shore access is facilitated by a Besenzoni passerelle plus carbon fibre tide rider side boarding ladder and gangway.

Entertainment and lifestyle systems are harmonised across the yacht. In the main saloon a ceiling‑mounted Smart TV integrates with an RTI interface via iPad, Apple TV and SKY Stream; the adjacent dining area enjoys RTI music entertainment, the aft deck seating and the sundeck both feature Bluetooth music, and the sundeck’s convivial bar complements the Riviera pool Jacuzzi. The owner’s suite, VIP cabin and guest cabins each feature Smart TVs with RTI control via iPad, Apple TV and SKY Stream. The captain’s cabin mirrors this specification, and the crew mess adds Smart TV, RTI via iPad, Apple TV and SKY Stream alongside dedicated galley equipment for efficient service. The galley itself is fully equipped, highlighted by a Rational oven and Miele refrigerators, and laundry is handled by two Miele washers and two Miele dryers.

Safety is to Large Yacht Code standards, with fire protection including two Dräger fireman’s sets, an engine room Novec 230 system, a galley duct CO₂ system and a Honeywell fire monitoring system for vigilant detection and response.

The tender and watersports inventory is complete and versatile. A Williams DieselJet 565 serves as the principal tender, complemented by a Zodiac SOLAS rescue boat with a 9.9 hp outboard. On the water, guests enjoy a two‑seat Yamaha Jet Ski, two stand‑up Jet Skis, two Seabobs, a Jobe SUP paddleboard, a wakeboard, water‑skis and snorkelling equipment, with scuba diving equipment available for underwater exploration.

Recent refit and maintenance have been executed to an exemplary standard. In 2024/2025 the yacht successfully completed her ten‑year Class and Flag surveys. A full paint job, including deckheads, refreshed her presentation, while network capability was transformed with the installation of two Starlink Maritime panels and one OneWeb Italian panel, plus new access points and two SKY Stream boxes. A tender major engine service was completed. All ducting in the galley, laundry and AC system was cleaned. Fresh water tanks, grey water tanks and black water tanks were cleaned and painted. Lazarette bilges and decks were repainted with non‑skid coating, the forepeak was repainted, and the forward fuel tanks were inspected and cleaned. Glazing works included replacement of VIP/brow area windows and aft bridge windows. On deck, anchor windlasses were overhauled and repainted with Awlgrip, and anchor chains were re‑galvanized. In the machinery spaces engine mounts were inspected, while the entire drivetrain received new Axiseals, new cutlass bearings, balanced propellers, shaft inspections with straightness and dye testing, and new rudder bearings.
