Energy Dissipation and Drag

Energy dissipation and drag describe the loss of kinetic energy from water motion through friction, viscosity, and surface resistance. In hydrodynamics, energy dissipation occurs as turbulent flow, shear forces, and internal friction convert organized motion into heat or micro-motion. Drag represents the resistance exerted by fluid contact with surfaces such as bottom contours, rails, and laminated skins. Together, these forces determine speed retention, water release, and control under pressure — balancing responsiveness with stability.
Shapers refine drag and dissipation through tuned edge profiles, surface textures, and lamination systems that maintain feedback, flex, and control.
