Glossary ReferenceGlossary Reference
Because you canít sail directly into the wind, in order to get to a point
directly upwind, you must tack, or turn, through the wind and zigzag
upwind towards your destination.
In order to tack, turn the landsailerís front through the wind. Keep the
sail trimmed in so that you keep up your speed as you turn through the
wind.
11
Steering the Landsailer
There are two things to consider when operating your landsailer: 1)
steering the front wheel, referred to as the "rudder wheel", and 2)
angling the sails referred to as "trimming the sail"
1) The rudder wheel allows you to steer your landsailer in the direction
in which you want to travel. The wheel is controlled by moving the right
joystick located on your remote control. Moving the joystick from right to
left will turn the landsailer to the left. Moving the joystick from left to
right will allow the landsailer to turn to the right.
2) The angle of the sail, as compared to the wind, will allow you to
control the speed of the landsailer. The angle, or "trim", is controlled by
moving the left joystick up or down. Moving the joystick down moves
the sail out or away from the center of the body, or hull, of the landsailer.
Moving the joystick up brings the sail closer to the center of the hull.
"Landsailer Sailing Instructions"
To help you get started, the instructions below will provide you the
correct sail angles known as "sail trim" in relationship to wind direction.
Finding the best balance between the sail trim, the landsailerís direction
of travel, and the wind direction will allow you to obtain the greatest
speeds.
6
The most challenging
direction is steering closer to
the direction from which the
wind is blowing or into the
wind. In order to sail your
landsailer close to the wind,
you must trim the sail much
more closely to the center of
the landsailer. If you are
racing upwind, the best pilots
will be able to find the
balance that will allow you to
sail as closely to the "no sail"
zone as possible.
To find the no sail zone
you can bring the sail
all the way in to the
center of the landsailer
and gradually steer
more and more into the
wind until the sail
begins to flap like a
flag, and loose the
wind. This is known as
"luffing." When the sail
is luffing, it has no
pushing or pulling
power. You can also
lose sail power by
steering more and more
away from the wind
without moving or
adjusting the sail until it
stalls.
10
Harnessing the Wind
When you are ready to sail, the first step is to determine from which way
the wind is blowing. Use the ribbon, known as a "telltale" attached the
top of the landsailerís mast to determine wind direction.
Most days, we can observe the force of the wind pushing objects such
as leaves blowing and flags flying. But, with the right equipment, such
as an airplane wing or a sail, which works very much like an airplane
wing, the wind can be harnessed to push and pull things in many
different directions - even into the wind!
Going into the wind (upwind), when the wind blows over the front end of
an angled sail, it divides and meets at the back end of the sail. Because
the wind on one side travels a farther distance around the curve of the
sail, and the wind on the other side travels a straight line, it creates a
low-pressure zone along the curved side of the sail. This force pulls the
sail, and the landsailer, attached to it forward, or towards the wind
changing the angle of the sail can change the amount of low pressure
the sail creates. When the sail is correctly angled into the wind, the
resulting force drives the sail forward at its maximum speed towards the
wind. Going downwind, the sail is no longer being pulled by the wind,
but it is actually being pushed.

There are many directions that you can sail your Landsailer.
The easiest direction is away
from the wind, also known as
"running with the wind" When
steering away from the wind,
let the sail out and point the
landsailer away from the
wind. The wind will push the
landsailer.
A more challenging direction
is parallel to the wind, also
called a "beam reach". If you
angle the sail 45 degrees
from the wind direction, you
can run the landsailer back
and forth parallel to the wind.
This angle will provide you
with the maximum speed for
the landsailer.
A general guideline for sail trim, or angle, is that when the landsailer is
pointed as close to the wind direction as possible, the sail is trimmed all
the way in. When going dead downwind, or with the wind behind, the sail
is let all the way out. When the wind is perpendicular to the boat, the sail
is halfway in, halfway out.
However, it is not possible to sail directly into the wind. The closest you
can sail towards the wind is about 45 degrees to either side of the wind
direction.
8
You can also turn around by turning the back of the landsailer through
the wind, also called a jibe, with the sails all the way out. This is usually
done when the landsailer is going away from the wind.

Assembly:
Now that you have finished assembling your Landsailer,
you are ready to learn how to sail!
2) Insert one size "9V" (6LR61)
Alkaline batteries.
1) Open or close the cover with
a Philips screwdriver.
2) Insert four size "AA" (LR6)
1.5V batteries.
1) Open or close the cover with
a Philips screwdriver.

Expert Level:
Once youíve mastered the basic directions, or points of sail, itís time to
put your Landsailing skills into action!
Set up different courses with your friends and see who can maneuver
your landsailer through the courses in the fastest times. Challenging
courses encompass all points of sail and can be upwind/downwind,
circular, triangular, or any shape.
