What this video covers

The custom 21.2-meter aluminum mast for a new expedition catamaran is currently in production at All Yacht Spars in Australia.1:49 The mast is constructed from 6005-T6 aluminum alloy, chosen for its structural reliability and cost-effectiveness compared to carbon fiber.18:16 The spar weighs approximately 328 kilograms bare, with total rigging weight reaching over 600 kilograms.2:45 Design specifications were finalized through a collaborative process involving the boat's owner, the spar manufacturer, and Quantum, which utilized Sail IQ software to model compression loads and wind patterns.13:25 The mast features custom additions including integrated mast steps, spreader lights, radar mounts, and specific conduits for electronics.8:58 The manufacturing process begins with heating solid aluminum billets to 500 degrees Celsius before pushing them through a custom die in an extrusion press.18:17 The resulting sections are stretched for straightness and joined during final fabrication.18:31 The project prioritizes a robust, repairable design suitable for long-term cruising rather than racing performance.11:37
