ABSTRACT:
The drift of a boat which lies at anchor is monitored by a piezoelectrical accelerometer which is fixed to the anchor and will be subjected to sharp accelerations in case the anchor is pulled over the ground. The signals emitted by the accelerometer are transmitted to the boat through a multiple strand conductor which is led to the boat parallel to the anchor chain. The transmitted signals are then compared with a preset threshold value. When this threshold value is exceeded, an alarm is triggered. In order to avoid fouling the anchor chain with the electrical cable the latter is wound on a drum, which always exerts a slight pull on the cable.
