It is one of the nice things about kitesurfing .... the commeraderie and community that help launch and land kites, but this can make you lazy and develop a false sense of security for times when you come back to the beach after everyone has packed up and gone. It is an essential skill to know what to do in all situations, not just the easy safe ones.
If you are coming in to a narrow beach in onshore winds, pull the pin whilst you are out in the water so that the kite lands on the beach and then wind your lines in the water in the manner prescribed in our Tips and Advice page. If you are worried about kite damage, drop it on the water and roll your lines. I know the latter option is unpopular due to getting a wet kite before pack up, but it's better than some of the darker consequences should things go wrong.
Learning this and other self reliant skills you will never need anyones help and will develop a better level of confidence in your own ability. It doesn't mean disregard the help of others, just know how to handle yourself.
Good winds,
