Hydraulic windlasses offer an advantage of constant speed under all load conditions and can be run almost constantly. If well built and correctly installed including the piping, modern hydraulic systems provide low maintenance and high effecieny for long term use. Central hydraulic systems either driven by main engines or by electric motors, can power windlasses beside other consumers on the vessel such as thrusters, capstans, cranes or sail winches. which reduces the investment cost.
