Historical Context

Alfred Mylne's design work encompassed both sailing and motor yachts across several decades. The single screw motor yacht represented a significant category of vessel type during the early-to-mid twentieth century, as motor propulsion became increasingly favoured for larger cruising yachts. Mylne's engagement with motor yacht design reflected broader industry trends, though his practice remained strongly rooted in traditional yacht design principles and craftsmanship.
