Structural design & ergonomics

• Profiles are engineered to concentrate material where bending and torsional stresses are highest, optimising stiffness-to-weight for boom applications.
• Section geometries allow straightforward integration of fittings: rivets, attachment points for vangs, mainsheet blocks and reefing gear are readily accommodated.
• Marine-grade aluminium alloy and standard marine surface treatment ensure resistance to corrosion and long-term dimensional stability in saltwater environments.
