Historical Context

Alfred Mylne practised naval architecture across several decades, during which auxiliary power became increasingly integrated into sailing yacht design. The auxiliary ketch—a two-masted sailing vessel with engine propulsion—represented a practical solution for commercial and private vessels requiring flexibility in varied wind and sea conditions. Design 411 reflects the period when such vessels were being refined, though the precise chronology of this design remains unestablished. The survival of seven drawings indicates a formally developed design concept, whether or not it proceeded to construction.
