Historical Context

Alfred Mylne's design practice encompassed diverse vessel types, including both sailing yachts and motor vessels. The designation T.S.M.Y. (twin screw motor yacht) places this design within the interwar and post-war period when motor propulsion became increasingly prevalent in yacht design. Twin screw configurations offered improved manoeuvrability and redundancy compared to single-screw arrangements. The name Ottowa suggests possible North American client interest or association, though no client details are recorded in the archive.
