G'day there,
Been pondering this for a while....Before I buy the bits and make one wanted to see if anyone had a better idea.
Basically a piece of wood, about the size of a large bread board, with a rope through the centre of it. Carabiner (simple 1 action type) on one end and a knot/loop on the under side. When theres a pole or suitable attachment point, wrap the rope around the pole, thread carabiner through loop and presto anchor point made. If nothing but sand, bury board on side and cover, attach to carabiner job done.
I've seen different versions of this in use and was surprised how well they held considering how shallow they are buried. Not alot of pressure applied when kite is just bobbing on its side on water/beach so not alot needed. Obviously assisted launch is better but as I'm having my first proper winter I'm finding most WA kiters are little girls and scared of the cold so I'm often alone

I also like the freedom of being able to launch and land unassisted anywhere, not having to come in cause everyone else has etc....I can self launch fine but have never been able to self land very well.
Any ideas before I start hacking away at a lump of wood would be good.....maybe the breadboard is a good idea....just need some good rope and a carabiner. She wouldn't notice would she???
Cheers
