Alpha and Rocker - Two Design Approaches that led to the Successful Challenge for the 2007 International C-Class Catamaran Championship
Bibliographic record
Abstract
In 2007 Canada entered its first challenge for the International C-Class Catamaran Championship and was victorious in capturing the trophy with five straight wins by Alpha CAN 6 over the venerable Cogito from the USA. Two boats were designed for this challenge - the first was Alpha, a wingsail catamaran, which incorporated some new thinking on sail configuration and hull shape. This made it a successful evolutionary, but not revolutionary, step from the current state-of-the-art boats. Compared to Cogito, the main rival, she had a taller, narrower and thinner wing, lighter construction and more circular hull cross section. The second was Rocker, the bold hydrofoil catamaran, using hulls from the same mold as Alpha and an identical wingsail as the driving force. The daggerboard hydrofoils automatically controlled the ride height with trim tabs, while the control of the rudder elevators was left to the helmsman. Although she flew well, was very controllable, and was spectacular to watch, Rocker could not match the 20 knot plus speed of Alpha.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
