Historical Context

Alfred Mylne designed across multiple yacht categories throughout his career. The 1960s represented a period of continued activity in motor yacht design, as post-war leisure boating expanded and owners sought reliable, well-appointed vessels for cruising. Twin Screw configurations became increasingly common in designs of this era for yachts of substantial size. The preservation of 42 drawings for Design 463 underscores the level of detail Mylne typically provided to builders and clients, even as his output evolved with changing maritime preferences.
