I don't do kite surfing (that's the North Sea out there - people that work out there wear survival suits in the Summer, and you want me to go out there in my keks??), so that leaves little choice but to stand still and fly.
Enter the beach-skates.
Step 1: The concept.
Beach-skates are simple things - they provide a smooth surface to skid on, and can increase the size of your foot-print so that you do not sink so easily.
