IMPROMPTU is a 50-metre Trinity Yachts motor yacht that has built one of the most consistent charter reputations in the American-built fleet, blending Patrick Knowles’s timeless interior design with exceptional deck spaces and an amenity package that keeps guests of all ages thoroughly entertained. Built in 2011, she successfully completed her 15-year ABS survey in 2025 alongside comprehensive engine rebuilds and generator services, leaving her in mechanical condition that is as strong as the day she was delivered. Her 2022 refit covered a full exterior repaint and state-of-the-art audio-visual and Wi-Fi upgrades, and she continues to be refined and maintained to an exacting standard under her current ownership. Knowles brought a classically styled, homely aesthetic to IMPROMPTU that makes her feel immediately welcoming: rich multi-wood detailing in the main salon, tetra-style bulkheads, wenge cabinetry and intricate inlay work create a warm and sophisticated atmosphere. The main salon features generous open-plan seating, a beautiful self-playing baby grand piano and a formal dining area for 12 forward, separated by an island credenza. A spiral staircase leads to the bridge deck, where a bespoke wine cellar makes a warm first impression before guests reach the skylounge with its full wet bar, L-shaped sofa and games table, perfect for poker evenings and casual gatherings. The sundeck is IMPROMPTU’s signature outdoor space: a custom raised waterfall Jacuzzi for 12 with intricate blue tilework takes centre stage, flanked by a large bar with seating, a barbecue, a dayhead and chaise lounges for long afternoons in the sun. An outdoor cinema makes evening screenings under the stars a highlight of every charter. Six staterooms accommodate 12 guests, led by the split-level main-deck master suite, which features a king-size bed, an elevated lounge with 180-degree views and his-and-hers en-suite bathrooms with a steam shower and Jacuzzi tub. A private study at the entrance and an adjacent walk-in closet complete a suite that is among the most thoughtfully designed in the American-built fleet. A bridge deck VIP surrounded by large windows and four lower-deck cabins, including three kings and a twin with Pullman, complete the layout. A 39-foot Nor-Tech 390 Sport towed tender with four 450hp engines serves as both a high-speed chase boat and a serious game-fishing platform. A crew of nine delivers enthusiastic, personalised service throughout. IMPROMPTU’s successful 15-year ABS survey in 2025, paired with full engine rebuilds and gearbox services, demonstrates the meticulous care that has gone into her maintenance and confirms that her mechanical platform is as strong as it has ever been. For families and groups seeking a yacht that delivers adventure, entertainment and genuine comfort in equal measure without asking them to choose between the three, IMPROMPTU represents one of the most well-rounded options in the American-built charter fleet. Her crew of nine is experienced, enthusiastic and deeply proud of the yacht, and the combination of their service and the yacht’s facilities makes for a charter that guests consistently describe as exceptional. She is available for charter with Northrop and Johnson, with summer programmes in the Mediterranean and winter programmes in the Caribbean.
