Two Oceans Marine Manufacturing has launched two custom Two Oceans 800E Power Catamarans, with Ultra Vires — launched in 2016 — being the first and, at the time, the largest power catamaran ever built in South Africa. Designed by award-winning Du Toit Yacht Design, Ultra Vires was custom-built as a floating home for a family passionate about kiteboarding and surfing.
Powered by twin Cummins 305 HP engines, she’s built for long-range, transoceanic cruising with a range of approximately 4,500 nautical miles. Her epoxy E-glass foam sandwich construction ensures strength, durability, and performance.
The yacht blends elegance with practicality, featuring open-plan, wood-and-monochrome interiors by Du Toit Yacht Design and Onnah Design. The spacious saloon and galley are fully equipped for luxurious liveaboard comfort, including air conditioning, a full entertainment system, ample refrigeration, and top-end appliances such as a dishwasher, washer-dryer, and ice-maker. A state-of-the-art navigation station is integrated into the saloon.
Outdoor living is just as refined. The upper and lower aft cockpits offer shaded lounge areas, custom outdoor furniture, a built-in braai, bar, and helm station. Teak-finished decks lead to toys and tenders, including SUPs, a jetski, a foredeck RIB, and a 21-foot tender on a large aft davit.
Accommodation includes four guest cabins — two in each hull, all en-suite with private access — and flexible double or twin fore cabins. Separate crew quarters in each hull provide space for four.
Ultra Vires is the result of a close, collaborative design-build process, creating a high-performance, luxurious ocean-going home that’s as elegant as it is capable.
