1. SYSTEM DESCRIPTION
The SD10 Sailboat Drive system makes it easy and
economical to install an autopilot on small to medium size
sailboats with access to a quadrant or tiller. The drive system
is powerful and fast - capable of delivering over 180 kg/400
lbs of cable thrust, with a normal H.O. to H.O. time of 12-15
seconds.
The system comprises of a Drive Unit, a Steering Cable and a
Universal Connection Kit. The drive unit can be installed in
any convenient location. The steering cable and connection kit
transmit the steering forces to the quadrant or tiller. Standard
steering cable length is 2 m (6 feet) – other lengths available
on request. The drive unit has a drive motor and solenoid
clutch which allows hand steering when disengaged. The drive
unit also has a built in adjustable thrust limiter and an integral
rudder feedback (RFB) device.

2. IMPORTANT INFORMATION
The Drive System will fit a large number of vessels, but please
note the following important information on operation,
installation and maintenance of the drive system.
2.1 Operation
In the event of uncontrolled automatic steering or other
emergency situations, automatic return to MANUAL steering
is provided by switching the autopilot to STBY, or by using
the Manual Override procedure.
Note ! It is strongly advised that the helmsman be formally
familiarized with this manual override procedure.
Manual Override Procedure
The helmsman can overcome the steering action of the drive
unit by exerting force on the steering wheel in the opposite
direction to the drive. With this action the drive unit thrust
limit will ‘slip’ allowing the helmsman to take control.
2.2 Mechanical Quick Release
The Cable end that attaches to the steering quadrant or Tiller
arm has a quick release pin that can be used to disengage the
cable from the main steering system therefore releasing the
Autopilot drive (see page
Note ! It is very important that the helmsman is formally familiarized
with the location of this during any passage.
