Hi

Took out my Naish Park 2012 (second hand) for the first time and the first time for me without being in a lesson. There was a pretty good amount of wind.

I was having no problems practicing my water starts until I was preparing to start with my kite at 12 o'clock when it lost its shape completely, the lines went slack and it crashed pretty badly. This ended in me pulling the safety chord and spending ages self rescuing back to the beach.

I didn't notice a drop in wind when this happened (and I didn't see any one elses kites drop out of the sky).

Any ideas of the cause??

Cheers

This can happen for several reasons when the kites at 12 o'clock. Best to leave it at 11 or 1 so if it suddenly falls it catches the wind, instead of mr tumble tumble!

wasnt a 9m green 2012 was it? i just traded mine in

has happened to me before, but thats when the wind had died and i was too busy perving on euro chicks playing catch up the beach to notice. like mentioned 11 or 1 is better to park the park

Did the kite flex in the wind? Could be too little air pressure.

which way did it fall out the sky? Did it back flip, nose dive, etc? Was it still pretty firm when it landed?

It started to fall the normal way up and then it quickly span round and nose dived into the water.

When it landed it started to power up and because it was upside down, I decided to release the safety.

-Check that the kite is properly inflated (should be hard to bend it in half)

-Check your line length, make sure that your center lines are about the same length as your back lines. Look for advice or line tuning videos.

-Avoid going out in light gusty winds, especially when there are ''holes'' in the wind below 15 knots.

-Avoid keeping your kite at 12 O'clock, this where it's most likely to fall off the sky when the wind is flukey

Some more points...

I will relate the issue to older kites ....say up to 2006 - (I am trying to avoid saying 1 kite is better than any other)

These kites often moved back and forward when sitting at 12 - this movement was exaggerated on gusty days or when at the edge of the kite's wind range (top and more often at the bottom). The kite accelerates forward with lifting force, gets to a point where the wind is starting to act on the top surface which pushes the leading edge down - if this was too powerful for the other balancing forces (drag, and lift rotation), the kite tucked and fell out of the sky (they still do!!).

Design changes have mostly removed this instability (test comments like - handles gusts really well etc etc point to this). However if you notice your kite slacking the front lines a little and hunting back and forward near or at the top of the wind window - ...
1) Make sure U do not have too much depower on.
2) Move your bar to break the cycle of the kite.....
a) In lighter winds - Rapidly pump the kite by moving the bar down then up.
b) In stronger winds - rapidly pump the kite bar left / right/ left / right..(This ups the drag acting on the kite and will force the Leading Edge up - by dropping the kite back a little in the window... giving U the chance to..
3) Re-position the kite off to one side or the other..(as above 11 or 1 oclock).

When the kite is off to one side it can still luff but is more likely to fall off to that side - not tangle the lines - and a chance to recover your kite - easier with experience

Even when your kite has tucked - if you can try and yank one of the steering lines - this can help the kite recover to one side and not invert (=tangle the lines through themselves)

BTW - cbulota's point on line lengths - is often the source of this type of problem with modern kites - where 1 kite is falling out the sky when others are not.

So there is the reason / theory - good luck with practice..
Cheers

Your kite crashed because it front stalled. This is normal behaviour. It requires input to avoid.

If the front lines are loaded and the wind increases a little then the kite will move forward. If the wind decreases then the kite has to move back. If the decrease is a little quicker than the kite can move then it will stall and crash.

When you thrash around in the water trying to get into water start position you load up the front lines. This also forces the kite forward. If you then release the tension on the lines (by any random movements you make) the kite will front stall.

The solution is to apply a little tension on the bar, or keep the kite moving a little to stop it coming too far forward.

This used to be called Hindenberging. It was made worse in old kites because they were nose heavy and would not drift back reliably. Modern kites are more balanced and will drift back but they can still front stall.
