Introduction
Larger yachts require a larger steering system to handle the higher
loads typically seen at the rudder(s). This system consists of two
distinct operating circuits;
a “manual” operated hydraulic system, consisting of a standard
SeaStar Helm pump and a hydraulic steering cylinder (fitted with
integral servo cylinder and power steering valve), and
a “power” steering system consisting of either an engine driven
pump (conventional), or, an eclectically driven power assist pump
(electric).
The manual circuit provides the control portion of the steering system
and the power circuit provides the power to turn the rudder(s). SeaStar
manufactures two options for the power circuit. Regardless of the
power option you choose, the correct steering cylinder(s) and helm
pump(s) (manual circuit) will need to be determined first (see page 8-2
for selection process). The power steering cylinders as well as the
helm pump are common between the two “power” systems. Before
choosing your preferred “power” option, you must determine what
cylinder is required for your application.
If you have any questions regarding the selection of your steering
system, please contact Technical Support for assistance “before”
you select your system.
