Watercraft Hull Design TRIZ Cases
- Boat Ballast Gate System for Pump-Free Insta Fill Wake
Rotatable gate controls ballast tank water flow using natural pressure differentials, eliminating pump complexity and leak risks.
- Human-Powered Hydrofoil Watercraft with Stair-Stepping Propulsion
Segmented hydrofoils lift the hull to cut drag, while stair-stepping struts convert human power into efficient forward motion.
