Historical Context

Alfred Mylne's design practice, which spanned several decades, produced vessels across diverse yacht categories. The designation "single screw" indicates a motor-driven vessel configuration, reflecting the gradual adoption of mechanical propulsion within yacht design during the early and mid-twentieth century. Design 500 occupies a position within this evolutionary context, though precise dating would require additional documentation. The preservation of 22 drawings suggests a design of some technical complexity, warranting thorough development before construction.
