Powered by a Mabuchi RS380 motor. By its physical size and shear grunt this is primarily a big boat winch. Ideal for classes such as the A, AC etc. However it should be noted that it is possible (but very rare) to have the Acetal gears on the this model to fail under shock load stall situations. However I personally choose to use an 380ES in my own A class yacht as the risk is very low and the saving in cost and weight I consider is worth it. Comes with 32s drum unless otherwise specified
