36‑Restricted Class Championship (1964). The national championship at Bournville attracted only six entries, highlighting already‑declining participation.
A major instructional feature on “Petrel”, an 18‑inch sailing cruiser:
Explains why true scale sailing models are difficult due to scaling laws.
Introduces bread‑and‑butter hull construction using lines plans.
Step‑by‑step guidance on interpreting sheer plans, waterlines, buttocks, and body plans.
Focuses on learning to work from professional drawings rather than kit assembly.

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.
