Bio-Inspired Variable Geometry Hull Optimization

Design and construct a scale model of a hull section utilizing flexible, non-rigid materials to simulate active morphing for drag reduction at varying Froude numbers. Your prototype must demonstrate a mechanical or tension-based actuation system capable of altering the hull's wetted surface area or bow profile to transition between displacement and semi-planing modes. Documentation must include an analysis of the center of buoyancy shift relative to the morphing geometry.

Materials: Flexible TPU sheets, thin steel tension cables, small servo motors, waterproof adhesive, polystyrene foam, and basic hand tools.
