Features
Introduction
SeaStar offers rugged 3-line Hynautic Heavy Duty steering systems
for most work and pleasure vessels up to 70 feet.
Heavy Duty helms combine one or two bi-directional axial piston
pumps with pilot check and make-up check valving. The result is a
unit which prevents rudder feedback, is very efficient (even at low
RPM), and is immediately adaptable to multi-station use.
A wide choice of helm displacements and cylinder configurations make
it easy to spec a system which can handle a variety of large boat
performance requirements and accommodate most user preferences.
How to Spec a System
1 From the application guide select components appropriate for the
vessel based on:
a) hull type—displacement or planing
b) length of vessel, and
d) number of steering wheel turns desired
2 Select the fitting and hose kits required, based on type of plumbing
(1/2" or 5/8" tubing or hose) and based on number of steering stations.
3 Confirm that there is sufficient space available in the dash and engine
compartment(s) for the steering components. Refer to helm and cylinder
dimensions on page 9-8 and page 5-4.
