Historical Context

The 1960s represented a transitional period in yacht design and construction. Twin screw motor yachts were gaining favour among owners seeking seaworthy, self-sufficient vessels with reliable propulsion. Mylne, having established his reputation primarily through sailing yacht design, continued to receive commissions for motor vessels and hybrid types throughout his later career. The twin screw arrangement, though more complex and costly than single propulsion, offered practical benefits that appealed to serious cruising owners.
