Morgan 462 (triatic): stress and utilisation in 3D

Masthead ketch. Generated by rigframe 0.1.0.dev0 DEMO from boats/morgan-462-ketch-triatic.yaml on 2026-11-06. Full report.

An engineering estimate, not a rig survey. 62 of the 85 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.
