AI-Augmented Solver

Three-Parameter Yacht Hydrodynamics

ML Form Prediction & ITTC-1957 Friction Line

This solver requires only three primary hull dimensions — Length on Waterline ($L$), Beam ($B$), and Draft ($T$). Trained regression models infer the remaining hull-form parameters (displacement, prismatic coefficient, and LCB), which then drive the resistance prediction. Total bare-hull resistance ($R_t$) separates viscous fluid friction from wave-making residual forces:

Total Bare-Hull Resistance
$$R_t = R_f + R_r$$

Where Rf is viscous skin friction and Rr is the ML-predicted wave residuary force.

Viscous Skin Friction ($R_f$)

Frictional scaling is derived from the ITTC correlation line, mapping the predicted wetted surface area ($S$) against the turbulent Reynolds Number ($Re$):

ITTC Friction Line
$$R_f = \frac{1}{2} \cdot \rho \cdot V^2 \cdot S \cdot C_f$$

The viscous drag coefficient is driven by: Cf = 0.057 / (ln(Re) - 2)²

Operational Control Workflow

1

Three-Parameter Hull Input

Provide only Length on Waterline (L), Beam (B), and Draft (T). The hull geometry updates live inside the WebGL canvas as you adjust the three primary dimensions.

2

AI Parameter Prediction

On each change, the trained models infer displacement, prismatic coefficient, and LCB. These predicted hull-form values appear live in the telemetry deck and refine the 3D hull shape.

Resistance Curve Analysis

Switch to the Analytical Plots view to inspect the Rf / Rr / Rt resistance matrix across the full Froude range, filter individual components, or export the curve as a CSV file.
