Historical Context
Alfred Mylne (1881–1969) was a Scottish yacht designer of considerable reputation, known for designs spanning cruising yachts, racing vessels, and larger motor sailers. His practice produced numerous designs throughout the twentieth century, many of which were built by various yards. Design 431 forms part of this broader catalogue of work. The archive preservation of sixteen drawings for this design indicates it received full technical development, whether or not it achieved multiple builds or widespread recognition in the racing or cruising fleet.
