There is a limit to the power you can practically generate with DC electrical systems, so for super yachts and other larger heavier crafts DC electric thrusters are rarely an option. The greater thrust and extended run time make hydraulic thrusters the ideal choice for commercial crafts and less manoeuvrable yachts. In conjunction with a good hydraulic system these thrusters offer continuous operation and you can get variable speed control with proportional control and valves. Side-Power's hydraulic thruster range from 100 to 550kg of thrust for use as either bow or stern thrusters.
SH 100 Thrust 80 kgs, Tunnel 185 mm, Propellor Power 6.5 kW.
SH 160. Thrust 200 kgs, Tunnel 250 mm, Propellor power 15 kW.
SH 240. Thrust 200 kgs, Tunnel 300mm, Prop power 18.4 kW.
SH 550 Thrust 550 kgs, Tunnel 386 mm, Propellor Power 33 kW
Hydraulic thrusters offer two advantages compared to electric thrusters. In conjunction with a good hydraulic system these thrusters offer continuous use. This is often necessary for boats such as fishing trawlers, small ferries and some larger yachts where thrusters are used for more than close quarter manoeuvres. The other advantage of hydraulic thrusters is the ability to control speed by means of a proportional control valve. With models from 100 kg to 550 kg of thrust for use as either bow or stern thrusters, Side-Power probably has a model for your boat.
