Abstract
This paper examines the control system characteristics of a vessel that uses Z-drives to actively reduce roll motion. Active roll control systems that use rudders and fins have been in existence for many years and the capabilities of such systems have been studied extensively. As an actuator, the Z-drive suffers from many of the same limitations as rudders; for example, the vessel's steering is also closely linked to the rudder motion. The Z-drive has an advantage over rudders and many fin-based systems in that it has the potential to be an effective actuator for roll motion reduction at low and even zero forward speeds: conditions in which a rudder is completely ineffective. Full-scale trial data is used to establish some design principles for a roll reduction system based on Z-drive operation.

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
