Hydrodynamic Insights

This tool estimates performance based on simplified hull resistance models:

  • Wetted Surface Area (WSA): Calculated based on the submerged hull volume proportional to the displacement.
  • Hull Speed: Derived from the power-speed relation P = 0.5 * ρ * v³ * WSA * Cd where Cd is a drag coefficient optimized for slender racing shells.
  • Dynamics: Values adjust dynamically as you modify boat class or payload weights.
