Historical Context

The ketch rig enjoyed considerable popularity in British yacht design during the early twentieth century, offering practical advantages for extended cruising and handling. Alfred Mylne, based in Glasgow, was an accomplished designer whose practice spanned several decades. Design 187 and the 1910 Diantha appear within the broader context of Edwardian and early twentieth-century yacht design, a period of substantial activity in British yacht building. The survival of six drawings indicates the design received formal development and documentation typical of Mylne's professional practice.
