Historical Context

The 1930s represented a transition period in yacht design and construction. Auxiliary cutters emerged as a practical solution for owners seeking the advantages of sail combined with the reliability of mechanical power. Alfred Mylne, working from his base in Scotland, was active during this era in designing vessels for a range of purposes and budgets. The preservation of 45 drawings for Design 315 demonstrates the systematic documentation methods employed in professional yacht design offices of the period. The auxiliary cutter rig, combining a mainsail with one or more headsails, became established as a versatile configuration suitable for cruising vessels of modest to moderate size.
