1 Introduction
1.1 Key Features
Your Race Master provides a unique combination of features:
Viewable from both sides of the boat
Two LCD displays mounted at an angle to permit viewing from either
side of the boat.
Solar Power
The Race Master is powered for life by the environment. Although
feature packed and highly visible in all conditions, current demand is so
low, and the supply so efficient, that the solar-powered display is self
sufficient.
Integrated Heading Sensor
The Race Master is a powerful racing compass; with functions for Race
Timer, Wind Shift and Line Bias.
Bar Graph display
Both screens of the Micronet Race Master incorporate a bar graph to
permit analogue display of Wind Shift, Speed Trim or Depth.
Remote control capability
By purchasing an optional Tacktick Remote Display, you can control
your Race Master from any location in the boat.

2.4 Power Management and Battery Life
What makes your Race Master possible is Tacktick’s revolutionary
approach to power management. By reducing the amount of power
being used by the electronics and maximizing the potential of the sun to
provide power, the Race Master is capable of virtually perpetual
operation.
Power status is indicated by two icons on the display:
Battery Level and Charge Rate
Used together these icons will show the condition of the power supply.
If using the Race Master at night, power usage can be reduced
dramatically by switching the Backlighting to level 1.
Note: If the internal battery is fully charged then it does not matter how
much the display is subjected to bright sunlight, no further charging is
required and the Charge Rate Indicator will remain low.
If the display is to be stored for a long period before next use (e.g. over
winter), ensure that the battery is fully charged before storage.
WWaarrnniinngg::Artificial light WILL NOT recharge the battery. Placing your
Race Master close to an artificial light will seriously damage the display.
Only recharge in natural daylight.

2.5 Sleep Mode
If there is no change in heading registered on the system for a period of
ten minutes your Race Master will switch off to conserve power.
2.6 Backlighting
At any stage of the display’s operation, press and hold for 2
seconds to access the lighting control.
Pressing and will scroll through the options OFF, 1, 2 and 3
whilst changing the backlighting.
Backlighting is automatically switched off in daylight as part of the
display’s power saving feature and will not operate in daylight.
2.7 Keylock
The Keylock feature protects from accidental key presses. Keylock can
be enabled or disabled in setup (see page 15), it is disabled by default.
When keylock is enabled, pressing a key causes the unit to give the
unlock key prompt. Press followed by to unlock the keys (the
keys will function for one minute, after which the keys will automatically
relock).
2.8 Audible Signals
At stages during its operation your Race Master will beep to indicate
moments of importance.
Power-up The display will issue a single beep as it is switched on.
Button Press A single beep is issued each time a button is pressed. A
second beep is issued when a button has been held
down for two seconds.
Timer A single beep will be issued at each minute of the
countdown.
With 1 minute left to go a beep will sound every 10
seconds.
With 10 seconds to go a beep will sound every second.
Countdown complete will be indicated by a single burst
of three beeps.
2.9 Safety and Disposal
Your Race Master contains Manganese Lithium Dioxide batteries which
should be disposed of correctly. Do not dispose of any instrument in
domestic waste. Refer to regulations in force in your country.
If in doubt return the instrument to Tacktick Ltd. for correct disposal.

3 Racing Functions
3.1 Some definitions and terminology
True Wind Direction (TWD), the current actual direction of the wind
over the water, expressed as a compass heading. If the boat is head to
wind, the TWD is the same as the heading of the boat.
Mean Wind Direction (MWD), the average of the True Wind Direction
over a sufficiently long period to even out any regular periodic changes
in the wind direction.
Tack Angle (TAK), the angle through which the boat turns when going
from close hauled on one tack to close hauled on the other. Typically this
is about 90 degrees.
Line Bias, the angle between the heading of the start line and a line at
right angles to the wind.
3.2 Improving Race Performance with the Race Master
Racing and Wind Shifts
Like most things in sailing, the wind does not remain constant in either
strength or direction.
The crew tend to react naturally to gusts but find wind shifts more
difficult to detect. However the wind does tend to shift in regular
patterns, oscillating from one side of the Mean Wind Direction (MWD) to
the other. Every shift in the wind requires the boat to alter its heading in
order to maintain a close hauled course. A shift that allows the boat to
change its heading closer to the Mean Wind Direction (MWD) is called a
“lift”; a shift that forces the boat to change course away from the Mean
Wind Direction (MWD) is known as a “header”.
In an oscillating wind, a boat that
regularly tacks when headed will spend
more of its time sailing a lifted course
and will sail a shorter distance to the
windward mark than a boat that regularly
sails a headed course. This gives the
boat sailing in the lifts a considerable
advantage.
In the diagram, the boat on the right sails
a shorter course by tacking when
headed and thereby sailing mostly in
lifts.
The opposite is true sailing down wind. A boat that gybes to sail in the
“headers” will sail a shorter course to the leeward mark than a boat that
sails a “lifted” course.

Optimise wind shifts
Your Race Master is the ultimate wind shift indicator, giving you precise,
clear numerical and graphical readouts.
Before the race, you program the Mean Wind Direction (MWD) and the
Tack Angle (TAK) into the Race Master (see section 3.3).
During the race, you get an instant visual display of:
Your heading as a large stable digital number (the upper display).
How far you are sailing above or below the mean close hauled
heading (lifted or headed) as a precise digital number (the lower
display).
How far you are lifted or headed in bar graph format for instant visual
impact (the vertical bar graph).
Race Master gives you this critical information when you are sailing both
upwind AND downwind. You sail your boat for maximum speed to
windward, using the Race Master to identify the headers and lifts to help
you decide when to tack. Timing your tacks and gybes is absolutely
critical to winning races and Race Master shows you the wind shifts
more clearly than ever before.
Racing and Start Line Bias
If the starting line is laid at exactly right angles to the wind, the distance
sailed to the windward mark is the same wherever the boat starts on the
start line.
If the start line is not laid at exactly
ninety degrees to the wind, there is
a favoured end to the line; a boat
that starts at the favoured end
starts upwind and therefore ahead
of a boat starting at the other end
of the line. The angle between the
actual line heading and the
theoretical line at right angles to
the wind is called the Line Bias;
the larger the bias angle, the
greater the advantage to be
gained from starting at the
favoured end of the line.
The diagram (right) shows the relationship between these values.
Optimise your start with the Race Master
Your Race Master has the ability to capture the Line Perpendicular (the
heading at right angles to windward of the start line) and to display the
Line Bias angle and the favoured end of the line.

3.3 Before the Race
Programme the Mean Wind Direction (MWD) and Tack Angle (TAK),
capture the Line Bias (LiNE) and set the Race Timer (TMR).
To set the Mean Wind Direction (MWD) and Tack Angle (TAK) in
“Single Button” mode
Go to the Wind Shift (WND) page.
Sail upwind for several minutes to determine your average close hauled
heading on each tack.
Press and hold . Rotating lines will appear on the display.
Steer your average close hauled course on either tack.
When the display shows the pop-up "TAC NOW", tack the boat and sail
your close hauled course on the other tack.
The rotating lines will reappear on the display, hold your close hauled
course until the Tack Angle (TAK) pop-up appears.
The displayed value can be adjusted using and .
To capture the Line Perpendicular and the Line Bias
Ensure that the Mean Wind Direction (MWD) has been captured (see the
section above).
Go to the Line Bias (LiNE) page.
Sail directly along the start line, then press .
A pop-up is displayed showing the Line Bias angle and the favoured
end of the start line based on the captured Mean Wind Direction (MWD).
When the pop-up closes, the bottom pane shows the Line
Perpendicular (the bearing at right angles to windward of the start line).
To check the direction of the Line Bias
If the wind changes prior to the start, provided you have captured the
Line Perpendicular, as described above, you can check the Line Bias at
any time as follows:
Go to the Line Bias (LiNE) page.
Steer the boat towards the eye of the wind until the Heading in the upper
pane matches the Line Perpendicular in the lower pane.
