We had a loose kite here in SRQ last week in about 18 mph after a harness hook broke at the welds. The damn kite motors downwind and it's time to say goodbye until it catches on a crab trap and starts flying in the middle of the pass. The kite's owner gets the kite off the crab trap, brings it back to the beach, and breaks down the kite. Then the kite (with no lines attached) gets loose again and blows off of the key. The next morning, a friend of the kite's owner finds the damn kite on the next key over and returns it.

Some days, luck is with you, some days it's not.

Wev'e had several harness hooks break in the last few weeks, so it is a good idea to attach your leash to something else on your harness just in case the hook goes.
