Historical Context

The triple screw configuration emerged during an era when motor propulsion was transforming yacht design. Mylne's practice encompassed both sailing vessels and motor yachts, reflecting the maritime industry's transition through the early and mid-twentieth century. The survival of design drawings in the archive, even when construction details are fragmentary, provides valuable evidence of Mylne's design activities and the range of vessel types his office undertook. Many yachts designed during this period were subsequently lost, substantially altered, or their histories obscured by time, making the archival record an important resource for maritime history.
