Abstract
High-speed monohulls are known to experience excessive motions and structural loads caused by accelerations and slamming when operating in heavy weather. This paper presents a concept of a new wave-piercing bow designed to reduce adverse motions and structural loads. That goal has been achieved by introduction of a bow form that features upper surfaces shaped to generate downward lifting forces, which counterbalance the displacement forces that lift the bow up while moving through a wave and initiate pitching motion; counterbalancing these forces stabilizes the hull. Extensive model testing has been carried out on several models between Deceber 2000 and March 2002. Resistance forces, accelerations and bow pressures were recorded and used to define critical loading cases, subsequently used in a global finite element analysis of the structural arrangement of a generic 165ft Gulf of Mexico crew boat, its scantlings determined using direct approach under ABS High Speed Craft Guide. The research indicated a potential for significant reduction of motions, structural loads, scantlings, structural weight and power requirements.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
