Catamaran crossbeam Z1371

Product description
New generation of beam designed as a crossbeam for modern catamarans. The Z1371 crossbeam has been CAD-designed to be assembled without welding and to be fully machined using 5-axis CNC technology. New crossbeam profiles and components have been developed to create a stronger and lighter beam while minimizing chafe points and reducing electrolytic corrosion between aluminium and stainless steel. All crossbeams are supplied with traceability labels.

Key features

• Dimensions: 270 mm x 155 mm
• Inertia (longitudinal): 2427 cm4
• Inertia (lateral): 1146 cm4
• Weight: 13.95 kg/m
• Designed for assembly without welding
• Fully machined using 5-axis CNC technology
• New profiles and components to reduce chafe points
• Anti-slip grooves integrated on the upper surface
• Crossbeam dolphin striker made from thick round tubing to limit sail chafing
• Traceability labels supplied with each crossbeam

Materials and corrosion control

• Stainless steel parts: AISI 316 grade stainless steel
• Beam profiles and chainplate extrusions: 6005A T6 alloy (stated as three times stronger than cast aluminium)
• Only the forestay attachment, beam tie-rod, trampoline sliders, and beam-to-chainplate connecting pins are made of stainless steel to limit galvanic/electrolytic corrosion

Design intent and suitability

• Specifically suited to modern catamarans
• Tie-rod end fittings and chainplates are integrated into the beam to minimize chafe points
• Objective: stronger, lighter beam with minimized chafe and reduced aluminium/stainless steel corrosion
