Flamenco – A Double-Chine Marblehead Design

Design Philosophy The A‑Class rule uses a sliding scale linking displacement, size, and sail area, encouraging innovation while penalising extremes.
Hull Form & Hydrodynamics: The hull features orthodox canoe‑body lines with maximum beam slightly abaft midships.
Fin & Construction Practicality: The fin is shown full size to simplify construction and ensure accuracy.
Lead ballast is kept clear of the garboard turn, allowing a clean fin–hull junction and improved flow.
Performance Expectations: Heavier “Turner”‑style designs tend to excel in light airs, while shallower hulls perform better in strong winds.
