The Build
From concept to start line
A foiling Moth is one of sailing's most technically demanding one-design classes. It rewards precision engineering and punishes shortcuts. That is why we chose it.
The Vessel
A foiling Moth
The International Moth is a single-handed sailing dinghy that flies above the water on hydrofoils. At full flight, only the foils and rudder touch the water — the hull is airborne.
The SuMoth Challenge adds a critical constraint: every material decision, structural choice, and fabrication method must meet measurable sustainability standards. That constraint does not reduce the engineering — it amplifies it.
Target Specifications
Loading model
Preparing the vessel viewer.
Engineering Systems
Five integrated systems
Hull Structure
Bio-composite construction. Sustainable reinforcement fibres with bio-based epoxy resin systems. Weight-optimized for foiling performance.
Hydrofoils
CFD-optimized profiles using OpenFOAM. Lift, drag, and cavitation analysis. Composite construction with precision surface finish.
Rig & Sail
Integrated sail control systems. Optimized for competitive performance within sustainability constraints. Carbon and natural fibre hybrid.
Control Systems
Wand-based ride height control. Flap mechanisms for foil angle adjustment. Mechanical systems designed for reliability.
Materials
Bio-based resins, flax reinforcements, timber structure, and recycled cores selected through lifecycle and structural review.
