Launched in March 2020, the Magnum 46 is the largest model in the versatile and popular Magnum Power Catamaran range, built by Two Oceans Marine Manufacturing. Highly customisable for both commercial and leisure use, the range includes the Magnum 2750 Centre Console and Walkaround, the Magnum 36 Walkaround, and the Magnum 46 Walkaround — particularly favoured as sportfishing vessels.
Design and development
Evolved from the successful Magnum 36, the Magnum 46 features a re-engineered hull with increased waterline length and beam, enhancing load-carrying capacity. The tunnel entry and exit zones have also been refined for improved performance. Above the waterline, lightweight foam sandwich construction has been used to reduce weight without compromising strength.
Designed in-house to surpass the capabilities of the 36-footer, the 46 offers improved performance and is well suited to inboard engines. Sea trials have exceeded expectations, confirming the new hull’s efficiency and seaworthiness.
Built for performance
Like its predecessors, the Magnum 46 is built to handle tough conditions — including the Cape of Storms. High-density foam in select hull sections adds safety and buoyancy. The walkaround cabin allows for safe, full-circle movement — ideal for serious anglers operating in rough seas.
The catamaran hull delivers excellent stability, a soft, dry ride, and strong following-sea performance — making it ideal for long offshore trips.
