Overview
New arrival
Currently near Build completion, to New Zealand Maritime Code 40A, this exceptional offshore power catamaran showcases the engineering, craftsmanship and practicality for which Kiwi boatbuilding is renowned. Designed as a true long-range cruising platform rather than a coastal entertainer, she combines heavy-displacement offshore capability with outstanding performance, cruising comfortably at around 20 knots and reaching speeds of approximately 27 knots. Every aspect of her design reflects New Zealand's reputation for building vessels that inspire confidence in demanding sea conditions. One of her defining features is an extraordinary level of engineering redundancy. Each hull operates as an independent system with dedicated fuel tanks, propulsion and machinery, providing exceptional reliability for extended passagemaking. Twin 800hp MAN diesel engines, six independent fuel tanks, twin watermakers producing a combined 300 litres per hour, dual freshwater pumps, lithium battery banks, intelligent power management with automatic changeover, hydraulic thrusters with integrated joystick control and Dynamic Positioning System all combine to create a vessel engineered to keep operating when it matters most. Comprehensive Simrad electronics, SeaZone vessel monitoring and duplicate helm stations further reinforce her offshore credentials. Onboard, the emphasis shifts from capability to comfort. The expansive cockpit and flybridge provide exceptional entertaining spaces, complemented by generous storage, a hydraulic swim platform capable of lifting an 800kg tender, and thoughtfully designed deck spaces throughout. Inside, the beautifully crafted oak interior, Corian galley with Fisher & Paykel appliances, reverse-cycle air conditioning, multiple refrigeration and freezer options, and spacious accommodation create a true home on the water. Whether undertaking extended coastal cruising, crossing oceans or simply enjoying time aboard with family and friends, this is a vessel designed to go further, stay longer and do so in complete comfort. Build will be completed in October 2026, enquire for a chance to some finishing touches in the beautiful machine.
