Operational history

A review in ''Yacht and Boat'' described sailing the design, "the boat is astonishingly easy to control. The steering does not load up at any time; to a degree, steering is an intellectual exercise, not a tactile one. By that I mean that when Glenn calls “pressure coming” and I wait for the helm to tell me that the boat feels the extra breeze, nothing happens. She simply accelerates in a straight line, with no need to wind off helm. It may be a different story in a sea and with tougher gusts; we had smooth seas, but there is never an acute angle of heel, or sudden lurch that upsets the crew. It's a terrible cliche, but this hull really, really is like a big dinghy."
