ergonomic carrying comfort and ease of use  with the original X-load transfer system,  which 

offers a better distribution of the weight.  
The rucksack should be packed carefully to achieve maximum comfort. First, place the glider 
inside the harness and then put the top of harness in the bottom of the rucksack with the glider 
side next to the back of the rucksack.  Finally, tighten the internal and external compression 
straps and adjust the shoulder and waist straps to ensure the equipment stays firmly in place 

when walking. There are also two storage pockets for accessories. 
An XXL rucksack is available as an optional extra for pilots that require it. 

 

Your harness  

The Boomerang9 is certified for use with all harnesses with variable cross-bracing (GH type). 
Practically all modern harnesses are GH type harnesses. Older harnesses with fixed cross-
bracing (GX type) are not certified and should not be used. Check with the manufacturer of the 
harness or your paragliding instructor if in doubt whether your harness is a GH or GX type 

harness. 
The adjustment of the harness chest strap controls the distance between karabiners and affects 
the handling and stability of the glider. Excessive tightening the chest strap increases stability 
but also the risk of twists  following glider collapse, and it also increases the frequency of 
getting collapses due to poor feedback from the glider. The risk of twisting is also strongly 
affected by the seating position of pilot. Flying in a laid back (reclined) position makes it much 
more difficult to react in time to prevent riser twisting. With the chest strap in a more closed 
position the glider also has more tendency to maintain a stable spiral, lengthening of the chest 

strap gives more feedback from the glider but decreases stability. 
Gin calculates and draws the plan of the glider with a distance between the carabiners of 44cm. 
DHV certification test flights are also carried out with this setting. We recommend setting a 
distance of 42cm to 50cm between the carabiners, depending on the size and design of the 
harness. There is no need to fly with a tight chest strap setting with the Boomerang9, as there 

is no tendency for it to feel unstable, unlike older gliders. 

Certified Weight Range  

The Boomerang9 must be flown within the certified weight range given in the reference section 
of this manual. The weight range is quoted as the total weight in flight, i.e. the weight of the 
pilot, glider, harness and accessories. The easiest way to check your total weight is to stand on 

weighing scales with all your equipment packed into your rucksack.
