Hydraulics Case Study A typical hydraulic system which can be found on a 60-70ft yacht featuring a custom-designed Commander 400 and a pump from a generator-clutched PTO output.The PTO pump is sized to match the thruster and powers the thruster only in docking mode while the Commander powers the rest of the system. However, when sailing the PTO pump will power all non thruster functions leaving the Commander as backup and for night/quiet operation. The control system is designed to use a barebones Commander 3/8 control box and a custom stainless control panel with a proportional paddle joystick giving fine thruster control. 18m (60ft) Typical Hydraulic Schematic
