My local beaches are all too soft for kite ground boards (KGBs), and I can't really justify buying a buggy, since I get out so rarely these days.
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.
On other beaches, with flatter, hard-packed sand, I have been able to skid quite far on the soles of my shoes. Unfortunately, as I said, my local beaches are all too soft for that.
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.
