If you find yourself typing on google maps ‘kitesurfing lessons near me’ and you are in or around Squamish you will most likely be directed to us at Squamish Watersports. If you would rather learn a bit more theory at home start with reading the kitesurfing lessons near me
series. The last articles in the kitesurfing lessons near me focused on ‘power and depower’, ‘the sweet spot’ and ‘the Angle of attack’. Now we want to talk about the backstall and the trim strap.
Backstall Reading all this might make us think that we are always going to get maximum power from the kite by sheeting the bar all the way in but doing this can actually have the opposite effect. By pulling the bar all the way in we might over sheet the kite, giving it an AoA which is too big and causing the airflow over the kite to get too turbulent for the kite to fly. Especially in light wind this will cause the kite to back stall and fall back into the wind window before landing on the water (unless we are quick enough on letting the bar back out). On the picture you can see how the wind flows smoothly over and underneath the kite until the angle of attack is do large, causing turbulence behind the kite
Trim strap The trim strap is still called the power and depower strap by many of us kiters. Even kiters who know better might still tell you to “power the kite up” or “depower the kite” by using the trim strap. This is usually because the concept of how the trim strap works can be a little hard to grasp. So here is what really happens. When pulling the trim strap in we effectively shorten the centre lines in comparison to the steering lines (i.e. lengthening the steering lines in comparison to the centre lines). Letting the trim strap back out does the opposite (it lengthens the centre lines in comparison to the steering lines). Having read the part about the AoA we might now think that using the trim strap changes the angle of attack on the kite but this is not really correct. Using the trim strap changes where the bar (sweet spot) is positioned on the sheeting lines. In other words: it changes the position of the bar from where the kite will depower by sheeting out slightly more or power up by sheeting in. Even after having understood this we probably still say “my kite is fully depowered”. Since most people refer to the trim strap as the power/depower strap everyone will know what we mean.
We will talk more about trimming the kite throughout this series.
