My husband initially pulls up the mudweight with a couple of short bursts then longer ones until he is sure the chain is not tangling. This also helps loosen the weight from the mud. His tactics have not let us down yet. If covered in mud, we leave the mudweight dangling in the water by an inch or so whilst moving and within a short space of time the mud is gone. In that short space of time, at least one person will call and tell us we have left our mudweight down! (I’m glad people do that in case one day we really do forget - again!) On the hire boats, is there any way of letting an electric mudweight down manually?
