The Magnum 8.5 is a high-performance coastal cruising catamaran that emerged from the vibrant multihull design scene in New Zealand. Developed primarily as a "bridge-deck" cruiser that fits within the strict parameters of the New Zealand 8.5-meter Class, the model represents a successful attempt to blend blistering race-pace performance with enough accommodation for a small family to cruise coastal waters. Built predominantly by Magnum Yachts in Auckland, the vessel was a key player in popularizing the "box rule" racing format, which emphasizes light displacement and a generous sail-plan-to-weight ratio. Unlike many cats of its era that favored volume over velocity, the Magnum 8.5 utilizes narrow, high-aspect hulls and a relatively low-profile cabin top to minimize windage and maximize speed through the water.
