Historical Context

The early twentieth century witnessed a fundamental shift in recreational yacht design, as motor propulsion gradually became viable alongside traditional sailing vessels. Twin screw configurations offered improved manoeuvrability and reliability compared to single-engine designs. Mylne's practice encompassed both sailing and motor yachts, reflecting the professional demands of his era. The Scottish designer's output during this period was substantial, with designs spanning diverse vessel types and sizes. Motor yachts of this period typically combined practical engineering with the aesthetic conventions established in sailing yacht design, a balance that characterised much of Mylne's work.
