Historical Context

Alfred Mylne's design practice extended beyond sailing yachts into motor vessel development, particularly during the interwar and immediate post-war periods. Twin screw configurations became increasingly common in yacht design from the 1920s onwards, offering advantages in sea-keeping, fuel efficiency distribution, and manoeuvrability in confined waters. The presence of PF97 in Mylne's records indicates systematic documentation of design work, though not all projects proceeded to construction or achieved public recognition.
