Beneteau Oceanis 440: stress and utilisation in 3D

Masthead sloop. Generated by rigframe 0.1.0.dev0 DEMO from boats/beneteau-oceanis-440-1994.yaml on 2026-11-06. Full report.

An engineering estimate, not a rig survey. 32 of the 62 inputs are still estimates; the report lists them.

Displacement × 8 Undeformed

Colour is utilisation on one scale: wires = tension ÷ design MBL; masts and spreaders = peak fibre stress ÷ MPa (assumed aluminium yield). Spar stress = |N|/A + combined two-axis bending. Dotted grey = slack wire. Drag to rotate, scroll to zoom, hover any member. The button tooltip names the solver for each case.
