SM Masthead Wind Transducer-Raymarine ST-60

Jim Anderson

On SM384 I have Raymarine ST-60 sailing instruments. Five years ago my masthead wind speed/direction transducer was damaged and I hired a rigger to replace it. There is a "long" model and a "short" model. The "short" model was used. Despite numerous calibration and bias settings and setup maneuvers per the instructions, done a couple of times per year, it has never consistently worked correctly, especially when sailing a wind angle going upwind. The transducer is mounted on the port side of the top of the mast; it points straight forward. Does anyone know whether Amel specifies the "Long" or the "Short" transducer, and if the transducer is supposed to point straight forward?
