Dometic SeaStar Power Assist


Suitable form most boat types.

The SeaStar Power Assist uses an electronically controlled hydraulic pump to provide on-demand power steering.


Dometic SeaStar Power Assist

The Dometic Seastar Power Assist unit can be installed on new SeaStar steering installations or as an easy retro-fit to existing systems. Hence suitable for most boat types. The SeaStar Power Assist uses an electronically controlled hydraulic pump to provide on-demand power steering. Designed to be easily installed into the hydraulic steering circuit between the helm and steering cylinder.

An additional feature allows the Power Assist to adjust automatically to the input voltage from the boats batteries to either 12V or 24V.

The Dometic SeaStar Power Assist can be used on boats with multiple engines and rudders, multiple steering stations and autopilots. As an in built  safety feature the steering system will automatically return to manual operation without any change to the number of lock-to-lock turns if power to the unit is interrupted for any reason.

As a result the Dometic SeaStar Power Assist helps eliminate steering loads and provides high levels of comfort and control making boating more pleasurable. This also allows the boat can be driven safely and easily even in the most extreme conditions. Also consider the Power assist Pro which delivers up to 1500 psi to suit Dometic SeaStar Pro helms.

SeaStar P/A (Power Assist) steering uses an electronically controlled hydraulic pump to provide “Power” for your SeaStar Hydraulic Steering system.

The SeaStar P/A system is comprised of two circuits: a hand operated manual system, which is the control element, and a hydraulic power pump, which is the working element.

The manual system consists of a helm pump with internal relief and check valves, as well as a built in reservoir. Two steering lines and a compensating line which provide a routing for fluid to transmit through the system, and a steering cylinder which moves the steering device on the boat from side to side.

The power system, is an electronically controlled hydraulic pump that boosts the fluid being sent from the helm pump to the steering cylinder (this will result in much easier effort at the wheel—even when under heavy loads). A compensating line connects the P/A unit to the helm pump, allowing the P/A unit to share fluid with the helm reservoir.

The SeaStar P/A is compatible with multiple steering stations, and with the use of an autopilot. In the event of a P/A power loss or failure the hydraulic system will automatically revert to a manual hydraulic system.
