• Longitudinal inertia: 601 cm4
• Lateral inertia: 265 cm4
• Weight: 4 kg/m
• Extruded profile manufactured in Europe
• Alloy: 6005A T6
• Compatible with luff-groove sails or sail slides
• Can be tapered on the forward face
• Machined using 5-axis CNC
• Anodized after machining and welding
• One-piece masthead machined from the extruded aluminum profile
• Aluminum through-bar to prevent electrolytic corrosion between aluminum and stainless steel
• Aluminum reinforcement plate between mast profile and spreaders to prevent local crushing from spreader compression loads
• Spreader tip with external clamping system
• Stainless-steel halyard exit with identification plate
• Gooseneck and vang bracket machined from extruded aluminum profile (extruded profile strength ≈ 3× conventional cast aluminum)
