imo the worst possible scenario is drifting in, having the lines get wrapped tightly around your ankles (from kicking your legs). Then, having those lines entangle on a crap trap buoy right in the break. As the waves pull you in, it pulls the float (and you) underwater.

If you get tangled in a crap trap float, make sure you are clear of all lines (and unhooked) or make sure you don't let go of the kite while you are cutting yourself free....
