1.1 Overview
D5557-2
Your Raymarine tiller pilot is a totally self-contained autopilot designed for tiller
steered sailboats. The autopilot is mounted between the tiller and a single
attachment point on the boat’s structure. It is designed for owner installation and
is ready for use after connection to the boat’s 12 V electrical system.
Operating modes
The tiller pilot has four basic operating modes:
• Standby mode: autopilot off
• Auto mode: autopilot engaged and locked onto a heading
• Track mode: autopilot on and maintaining a track between two waypoints
created on a navigation system
• WindTrim mode: autopilot on and maintaining a course relative to an
apparent wind angle
SeaTalk and NMEA compatibility
The tiller pilot is SeaTalk compatible, so it can share data transmitted from other
Raymarine SeaTalk instruments:
• wind information from a wind instrument can be used for wind vane steering
without the need to install a separate vane
• track information, from a navigator, enables the autopilot to provide waypoint control
• boat speed from a speed instrument can provide optimum track keeping performance
4 ST1000 Plus & ST2000 Plus Tiller Pilots
• SeaTalk compatibility also allows additional fixed and hand-held autopilot
control units to be easily connected at secondary steering and control positions
The ST1000 Plus and ST2000 Plus tiller pilots can also be used with any navigator
transmitting NMEA 0183 or NMEA 0180 data.
The tiller pilot can be calibrated to suit each installation to provide maximum
performance with many types of boat.

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 product performance, personal injury and/or
damage to your boat.
WARNING: Electrical safety
Make sure the power supply is switched off before you make any
electrical connections.
WARNING: Navigation aid
Although we have designed this product to be accurate and
reliable, many factors can affect its performance. As a result, it
should only be used as an aid to navigation and should never
replace common sense and navigational judgement. Always
maintain a permanent watch so you can respond to situations as
they develop.
Your Raymarine autopilot will add a new dimension 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 AT ALL TIMES, to take manual
control in an emergency.
• Make sure that all crew members 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 position 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 significant errors under some circumstances and the autopilot will not be able to detect these errors.
Product disposal
l
When you want to dispose of this product (for example, at the end of its
working life), please do so in accordance with local regulations.

2.1 Overview
WARNING:
Passage making under autopilot control is an enjoyable
experience that can, if you are not careful, lead to the relaxation
of the permanent watch. Always maintain a permanent watch no
matter how clear the sea may appear to be.
• The tiller pilot always powers up in Standby mode (indicated by a flashing ‘C’
alongside the boat’s current compass heading).
• The tiller pilot is controlled using simple push-button operations, all of which
are confirmed with a short beep. In addition to the main single key functions,
there are several dual key operations.
• To select automatic steering:
• steady the boat on the required heading

Automatic deadband control (Auto Seastate)
In Auto, WindTrim or Track modes, the tiller pilot is set to AutoSeastate (automatic
deadband control) as a default. This causes the pilot to gradually ignore repetitive
movements of the boat and respond only to true course variations.
By preventing unnecessary rudder movement, AutoSeastate provides the best
compromise between power consumption and course keeping accuracy.
If you want to switch off the AutoSeastate feature:
1. From Auto, WindTrim or Track mode, press
-1 and +1 together to switch from
AutoSeastate to Fixed Minimum Deadband.
2. The “
°” sign flashes when Fixed Minimum Deadband is selected. Minimum
deadband provides the tightest course keeping possible, at the expense of
increased power consumption and drive unit activity.

To switch back to AutoSeastate, press -1 and +1 again.
Note:
The autopilot reverts to Automatic De adband Control each time you select Standby
mode.
Operating hints – trim changes
CAUTION:
Only make major course changes when steering MANUALLY. This
ensures that the boat will safely clear any obstructions or other
boats, and you can take into account the changed wind and sea
conditions on the new heading before engaging the autopilot.
Large course changes which change the apparent wind direction can produce
large trim changes. When a sudden trim change occurs (for example due to
weather helm or sail imbalance) there will be a delay of up to one minute before
the automatic trim applies rudder to restore the locked heading.
In these situations, the autopilot will not immediately assume the new automatic
heading, and will only settle onto course when the automatic trim has been fully
established. To minimize this problem, use the following procedure to make
major course changes:
1. Note the required new heading.
2. Press
3. Bring boat onto the new heading and fit the pushrod back onto the tiller pin.
4. Press
5. Bring your boat onto the final course in 1° steps using
standby, remove the pushrod from the tiller pin, and steer manually.
auto and let the boat settle on course.
-1 or +1.
Gusting conditions
In gusting conditions, the course may tend to wander slightly, particularly if the
sails are badly balanced. By improving sail balance, you can improve course
keeping.
If you take the following precautions, the autopilot will be able to maintain
competent control even in gale force conditions:
• 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.
• It is also advisable (whenever possible) to avoid sailing with the wind dead
astern when there are very strong winds and large seas.
• Ideally, the wind should be at least 30° away from a dead run.
14 ST1000 Plus & ST2000 Plus Tiller Pilots
• In severe conditions, it may be advisable to remove the mainsail altogether
and sail under headsail only.
2.3 Switching display illumination on and off
You can switch the display illumination on and off when the tiller pilot is in
Standby mode:
• from Standby mode, press
between on (L1) and off (L0)
• to return to the previous mode either wait 10 seconds or press the appropriate
mode key
Note:
The tiller pilot normally powers-up with the illumination switched on (L1).
If other SeaTalk instruments or autopilot control units are connected via SeaTalk,
you can also control the tiller pilot’s illumination from these units.
2.4 Using Track mode
In Track mode, the tiller pilot maintains a track between waypoints created on a
navigation system. The tiller pilot computes any course changes to keep your boat
on track, automatically compensating for tidal streams and leeway. To operate in
Track mode, the tiller pilot must receive cross track error information from either:
-1 and +1 together to switch the illumination
D364-2
• a SeaTalk navigator, or
• a non-SeaTalk navigation system transmitting NMEA 0180 or 0183 data
Selecting Track mode
When you select Track mode, the tiller pilot can acquire the track in one of two
ways:
• automatic acquisition – when both cross track error and bearing to waypoint
data are available
Chapter 2: Using the Tiller Pilot 15
• manual acquisition – when Cross Track Error is the only available information
Automatic track acquisition
If cross track error and bearing to waypoint data are both available (via SeaTalk or
NMEA), the pilot can acquire a track automatically:
1. Bring the boat to within 0.1 nm of track.
2. Press
3. Press
4. An alarm will sound and the display will alternate between:

Manual track acquisition
If your navigator only provides cross track error information, you must acquire the
track manually:
1. Steer the boat to within 0.1 nm of track.
2. Bring the heading to within 5° of the bearing to the next waypoint.
3. Press
4. Press
auto.
-10 and +10 together to enter Track mode:
• the autopilot will start tracking to the waypoint
• the display will alternate between cross track error and the locked pilot

Manual track acquisition at low speeds
Using manual acquisition at low speeds requires additional care as tidal streams
have a far more significant effect at lower speeds than at higher speeds.
In general terms, if the tidal flow is less than 35% of the boat’s speed, you will not
notice any difference in the tiller pilot’s performance in Track mode. However, you
should take extra care during manual acquisition, as follows:
• before you select Track mode, make sure that the boat is as close as possible
to track, and that the direction made good over the ground is as close as possible to the direction of the next waypoint
• positive checks of the boat’s position at regular intervals are vital, especially if
you are close to potential navigational hazards

Returning to Auto from Track mode
To return to Auto mode from Track mode:
• press

• press -10 and +10 together.
Cross track error (XTE)
Cross track error (XTE) is the distance between your current position and the
planned route. This is displayed in nautical miles (nm) and is taken directly from
your navigator.

Tidal stream compensation
Under most operating conditions, Track mode will hold the selected track to
within ±0.05 nm (300 ft) or better.
The autopilot takes account of the boat’s speed when computing course changes
to ensure optimum performance over a wide range of boat speeds. If speed data
is available, the autopilot will use the measured boat speed. Otherwise it will use
the default cruise speed entered in Calibration Level 5 (see

Waypoint arrival and advance
CAUTION:
Waypoint advance will only operate if the tiller pilot receives
valid bearing to waypoint and waypoint name information.
The tiller pilot can only decode the first FOUR characters of a
waypoint name. It will not be able to decode names longer than
four characters, which will stop the waypoint advance feature
from working.
If your navigator transmits valid waypoint name and bearing to waypoint data,
you can advance from one waypoint to the next by pressing
together.

Chapter 2: Using the Tiller Pilot 19
Arrival
As the boat passes the target waypoint, the navigator manually or automatically
selects the next target waypoint. The pilot will then:
• detect the new target waypoint name
• sound the waypoint advance alarm
• display the new bearing to waypoint and the direction the boat will turn to
acquire it
Advance
When the waypoint advance alarm is sounding, the tiller pilot will suspend Track
mode and maintain the current heading:
• check that it is safe to turn onto the new track
• press the
alarm and turn the boat towards the next waypoint
Unless you accept the waypoint advance in this way, the alarm will continue to
sound and the tiller pilot will maintain the current course.

• if the boat remains within 0.1 nm of track, there is no need to steer back
towards the track

Safety in Track mode
WARNING:
Track mode provides accurate track keeping even in complex
navigational situations. However, it is still the skipper’s
responsibility to ensure the safety of their boat at all times
through careful navigation and frequent position checks.
Passage making in Track mode assists precise navigation and removes the tasks
of compensating for wind and tidal drift. However, you MUST still maintain an
accurate log with regular plots:
20 ST1000 Plus & ST2000 Plus Tiller Pilots
Confirming position at the start of a journey
• At the start of a journey you must always use an easily i dentifiable fixed object
to confirm the fix given by the navigation system.
• Check for fixed positional errors and compensate for them.
Verifying computed positions
• Always verify the computed position with a dead reckoned position, calculated from the average course steered and the distance logged.
Plot frequency
• In open water, you should make plots at least every hour.
• In confined waters or when near to potential hazards, you should make plots
more frequently.
Setting waypoints
• Local variations in radio signal quality and changes in the tidal stream can
produce deviations from the desired track. When setting waypoints, remember that deviations can occur.
• Thoroughly check along each track. Check up to 0.5 nm each side of the track
to ensure that there are no hazards within this zone.
• For the waypoint advance function to work, the last four characters of adjacent waypoint names must be different.
Warning messages in Track mode
