Abstract
A numerical model for the coupled dynamics of a small liferaft and fast rescue craft in a surface wave is presented. The equations are formulated in 2D using the methods of Kane and Levinson (1985) and solved numerically using a MATLAB® Runge-Kutta routine. It is assumed that the motion normal to the wave surface is small and can be neglected, i.e. the bodies move along the propagating wave profile. The bodies are small so that wave diffraction and reflection are negligible. A Stokes' second order wave is used and the wave forces are applied using Morison's equation for a body in accelerated flow.Wind loads are similarly modeled using drag coefficients. Comparison with model tests performed at the Institute for Ocean Technology shows good agreement. The model provides guidelines for predicting the tow loads and motions of small craft in severe sea states.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
