Safety notices
WARNING: Product installation
This equipment must be installed and operated in accordance
with the instructions contained in this handbook. Failure to do so
could result in poor pr oduct performance, personal injury
and/or damage to your boat.
WARNING: Electrical safety
Make sure the power supply is switched off befor e you make any
electrical connections.
WARNING: Calibration
We supply th is product calibrated to default settings tha t should
provide initial stable performance for most boats. T o ensur e
optimum performance on your boat, you must complete Chapter
6: Commissioning the Autopilot before use.
WARNING: Navigation aid
Although we have designed this pr oduct to be accurate and
reliable, many factors can affect its performance. As a result, it
should only be used as an aid to n avigation and should never
replace common s ense and navigational judgement. A lways
maintain a permanent watch so you can respond t o situations as
they develop.
Y our Raymarine autopilot will add a new dim ension to your boating
enjoyment. However, it is the skipper’s responsibility to ensure the
safety of the boat at all times by following these basic rules:
• Ensure that someone is present at the helm A T ALL TIMES, to
take manual control in an emergency .
Preface ix
• Make sure that all members of crew know how to disengage the
autopilot.
• Regularly check for other boats and any obstacles to navigation –
no matter how clear the sea may appear, a dangerous situation can
develop rapidly.
• Maintain an accurate record of the boat’s posit ion by using either
a navigation aid or visual bearings.
• Maintain a continuous plot of your boat’s position on a current
chart. Ensure that the locked autopilot heading will steer the boat
clear of all obstacles. Make proper allowance for tidal set – the
autopilot cannot.
• Even when your autopilot is locked onto the desired track using a
navigation aid, always maintain a log and make regular positional
plots. Navigation signals can produce signifi cant errors under
some circumstances and the autopilot will not be able to detect
these errors.
EMC conformance
All Raymarine equipment and accessories are designed to the best
industry standards for use in the recreational marine environment.
The design and manufacture of Raymarine equipment and
accessories conform to the appropriate Electromagnetic
Compatibility (EMC) standards, but correct installation is required to
ensure that performance is not compromised.

2 ST7001+ Autopilot Control Unit - Owner’s Handbook
Functions with Type 150/150G and 400/400G autopilots
The functions provided with T ype 150/150G and Type 400/4000G
autopilots depend on whether the course computer contains an
internal GyroPlus yaw sensor:
Type 150G/400G (with GyroPlus) Type 150/400 (without GyroPlus)

Extended systems
Y ou can connect the ST7001+ to other Raymarine SeaT alk
equipment so it can send and receive SeaTalk data:
• it can use wind information from a SeaTalk wind instrument for
Wind Vane steering
• it can use waypoint information from a SeaT alk navigation
instrument to provide track control
• it can use boat speed from a SeaTalk speed instrument to optimize
track-keeping performance
Y ou can also use the ST7 001+ autopilot with any navigator
(GPS, Decca, Loran) or wind instrument that transmits National
Marine Electronics Association (NMEA) 0183 data.
The ST7001+ can display SeaT alk and NMEA instrument data in a
user-defined selection of data pages. When you are usin g the
ST7001+ to repeat instrument data, i t shows a ‘pop-up’ pilot page for
5 seconds whenever you make a change in autopilot control.
Compatibility with other autopilots
The ST7001+ is also compatible with Raymarine T ype 100 and
T ype 300 course computers (see the Appendix for more details).
Y ou can also use it as an additional repeater control unit for any
SeaTalk autopilot system, allowing autopilot control from a
secondary location.

Adjusting performance – Type 150G/400G
The main way you can adjust the performance of T ype 150G/400G
(GyroPlus) autopilot systems is by changing the response level. Thi s
is the only user adjustment you should need to make to t he autopilot
on a regular basis.
The response level controls the relationship between the autopilot’s
course keeping accuracy and the amount of helm/drive activity.
T ype 150G and 400G autopilot systems have 9 l evels of response:
• level 1 gives the least pilot activity to conserve power, but may
compromise short-term course-keeping accuracy
• levels 4 to 6 should give good course keeping under nor mal
operating conditions – with crisp, well controlled turns but
without being over-aggressi ve
• level 9 gives the tightest course keeping and gr eatest rudder
activity , but may lead to a rough passage in open waters as the
autopilot may ‘fight’ the sea
oror
2 Basic Operation
D3320-2
When you require extra tight course keeping (e.g. for pilotage in
confined and sheltered waters), increase the setting. If you want t o
minimize drive activity and conserve battery power , decrease
the setting.
8 ST7001+ Autopilot Control Unit - Owner’s Handbook
Y ou ca n adjust the default response level in either User or Dealer
Calibration (see page 89). This determines the default power-up
response level.
However, when using your aut opilot on a day-to-day basis, you can
make temporary adjus tments to the response level. By doing this
you can match autopilot performance to different conditio ns.
Temporary changes to response – Type 150G/400G
With these points in mind, you should use the following procedure to
make temporary adjustments to the response level when required:

Chapter 2: Basic Operation 9
Adjusting performance – Types 150/400 and 100/300
T o adjust the performance of T ype 150/400 (non-GyroPl us) and
T ype 100/300 autopilot systems you can change the response l evel.
Response level – Types 150/400 and 100/300
The response level controls the relationship between the autopilot’s
course keeping accuracy and the amount of helm/drive activity.
Y ou can adjust the default response level in either User or Dealer
Calibration (see page 89). This determines the default power-up
response level.
However, when usi ng your autopilot on a day-to-day basis, you will
need to make temporary adjustments to the response level. By doing
this you can match autopilot performance to different conditi ons.
T ype 150/400 (without GyroPlus ) and T ype 100/300 autopilot
systems have three different response levels:
• Response Level 1: AutoSeastate on ( Automatic deadband )
This setting causes the autopilot to gradually ignore repetitive
boat movements and only react to true variations in course. This
provides the best compromise between power consumptio n and
course keeping accuracy, and is the default calibration setting.
• Response Level 2: AutoSeastate off (Minimum deadband)
This setting provides tighter course keeping. How ever, this
results in increased power consumption and drive unit activity .
• Response Level 3: AutoSeastate off + yaw damping
This setting provides the tightes t possible course keeping by
introducing counter rudder yaw damping. You can adjust the
counter rudder setting in Dealer Calibration (see page 95)
To make a temporary change to the response setting:
1. Display the
the
-1 and +1 keys together momentarily .
2. Press

Note: Y ou will lose these temporary changes to response level
whenever the system is powered off. You can make permanent
adjustments in User or Dealer Calibr ation (see page 89).

Off Course warning
= deviation to port
= deviation to starboard
D4229-2
The ST7001+ activates the OFF COURSE warning when the boat has
been off course from the locked heading by more than the specified
angle* for longer than 20seconds. It shows whether the deviation is to
port or starboard.
Note: * Y ou can adjust this specified off course angle i n Dealer
Calibration (see page 97).
2 Basic Operation
1. T o cancel the off course warning, press
standby t o return to hand
steering.
2. Check whether your boat is carryi ng too much sail, or whether the
sails are badly balanced. Y ou can usually signif icantly improve
course keeping by improving the sail balance.
Note: T he ST7001+ also clears the warning if the heading r ecovers,
if you change the course, or if you change the operating mode.
Dodging obstacles and then resuming course
T o avoid an obstacle when your boat is under autopilot contr ol, you
can dodge the obstacle and then resume your previous course.

Preventing accidental gybes
Note: Fo r the gybe inhibit feature to work, the autopilot needs
suitable wind information (see page 25).
The gybe inhibit feature stops the boat from performing an AutoT ack
away from the wind – this will prevent accidental gybes. On T ype
150/150G and 400/400G autopilots, you can turn of f this feature if
required:
• with gybe inhibit on:
• you will be able to perform an AutoTack into the wind
• to prevent accidental gybes, the autopilot will prevent the bo at
from performing an AutoT ack away from the wind
• with gybe inhibit off:
• you can perform an AutoT ack into or away from the wind.
Note: Gy be inhibit is switched on as a default. On T ype 150/150G
and Type 400/400G autopilots you can swit ch it off in User or Dealer
Calibration (see page 87).
2 Basic Operation
Gusty conditions
In gusty conditions, the course may tend to wander sl ightly ,
particularly if the sails are badly balanced. If you take the following
precautions, the autopilot will be able to maintain competent control
even in gale force conditions:
14 ST7001+ Autopilot Control Unit - Owner’s Handbook
• Y ou can significantly improve course keeping by improving the
sail balance:
• do not allow the boat to heel over excessively
• ease the mainsheet traveller to leeward to reduce heeling and
weather helm
• if necessary, reef the mainsail a little early
