The consequences of a boat not fitted with rope stripper can be varied. Engines wrenched off their mountings, stern gear and gearboxes damaged. These photos were from the gearbox of a Mussel Industry vessel, wherein no rope cutter was fitted to the shaft. For more protection to the gearbox, a rope cutter and flexible coupling is suggested to be fitted. The flexible coupling not only serves as vibration dampener, it also designed to fail first before any damage can be transferred to the gearbox.
