 Spud Rowsell and Jon Turner won the Merlin Rocket Championships in "Foot-Loose" at Abersoch in 1978 with a points performance that has never been bettered and guaranteed the future success of Morrison's approach to designing a complete boat.Morrison's first direct exposure to designing in the more restricted One Design Classes, classes of dinghy which are supposed to all be nearly identical, subject to normal building tolerances, came with an invitation to design an "optimised" version of the Ian Proctor classic design the Wayfarer for Gordon Frickers who is now a well known maritime artist.The resulting boat, "Wellington" was raced very successfully and Morrison went on to "optimise" designs in many one design classes as diverse as the Salcombe Yawl and the International Fireball, in the latter winning the World Championships with Jon Turner in Weymouth Bay in 1981.
