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.
