Did you mean disconnect or depower?

If you really meant disconnect then the broken buckle was just an inconvenience, but the lack of ability to kill the kite or release it is a problem you need to get sorted out asap.

Worst case... imagine what would have happened if you got tangled in a crab trap and pulled under water? How quickly could you have released the kite?

Most people don't realize that if they get tangled in a crab trap, they are going under water in about 4 seconds and STAYING there as the kite pulls the float down wind.

Make sure you can ditch the kite in about 2 seconds with your eyes closed (by feel only).
