Historical Context
Triple screw configurations emerged as a distinctive feature of Edwardian and inter-war motor yacht design. This arrangement, employing three independent propulsion units, offered significant advantages in vessel control and power management compared to twin or single screw alternatives. Such designs were typically commissioned by clients requiring both performance and the prestige associated with advanced engineering. Alfred Mylne's practice encompassed motor yacht design throughout this period, adapting traditional yacht design principles to emerging mechanical propulsion technologies. The survival of Design 1149 as a drawing record indicates its place within Mylne's substantial output, though the design's commercial or constructional significance cannot be determined from currently available information.
