We recommend initially adjusting the distance of the chest strap according to the table. Then if
necessary, make slight adjustments. In general, the carabiner distance should not be set too narrow!
For fl ight comfort and safety it is very important that you fl y with a suitable, properly adjusted
harness. In practice, it turns out that few pilots have a harness that suits their fl ying style and
paraglider. If you have any questions or doubts regarding the use of your harness with the
Boomerang 12, please contact a GIN dealer or Gin Gliders directly.
Reclined harnesses are generally completely enclosed and often have a very low main attachment
point. Active
fl ying is very different with them than with an upright harness. To achieve the same level
of e ffi ciency and safety in fl ight with a reclined harness which you are accustomed to with an upright
harness, you must systematically learn the appropriate techniques and gain a good deal of
experience.
If any problems or disturbances are encountered when fl ying with a reclined harness, the pilot must
immediately assume an upright seating position. Extreme fl ight manoeuvres fl own in a reclined
position drastically increase the risk of twist. In addition, pilots often underestimate the reduction in
control travel caused by
fl ying an extreme fl ight manoeuvre.
There is an increased risk of twist when using a reclined harness if a large section of the canopy
collapses. If there is an asymmetric collapse and the pilot tips sideways, the resulting twist around the
vertical axis with a poorly positioned harness leads to a reduction in control travel. This quickly causes
an unintended stall on the open side.
It is a mandatory requirement to carry an approved reserve for use in emergency situations where the
paraglider fails and recovery is not possible, for example after colliding with another aerial sports craft.
In choosing a reserve, you should be careful that you remain within the speci
fi ed take-off weight. The
reserve is fi tted according to the manufacturer’s instructions.
Be sure to fl y your glider within the certi fi ed weight range given in the Technical Speci fi cation section.
The weight refers to take-off weight: pilot, incl. clothing, glider, harness and equipment.
The reactions are quite different at the upper- or lower weight range. If you fl y at a high wing-
loading, the glider shows dynamic fl ight behaviour with fast reactions. This may be an advantage in
strong wind conditions, but considerable pilot skill is required.
The dynamics are reduced somewhat in the middle and lower part of the weight range.
The EN 926-2:2015 and CCC 2020 describes the weight measurement with: “All weights are subject
to an acceptable tolerance of ± 2kg”. Therefore a slight overload of the wing would be within EN/CCC
tolerances. However,
fl ying over the maximum weight further increases the dynamic fl ight behaviour.
In small bubbles, the wing has more horizontal momentum and less tendency towards lifting. A test
fl ight is always recommended if in doubt.
