After one of the local boys made a simple slider box out of an old table and a bit of pvc pipe about 2m in length.
The idea of making an pvc rail that is about 4-5m in length that is easy assembled and disassembled and can be transported with ease came into my mind today.

I was thinking for the rail its self some 150mm dia PVC that is 4m in total length but with a join mid way. In on of the sections I was going to put a bend of about 30 deg in it so that it can run into the water.

For the legs I was thinking 100mm Pvc maybe 3 or 4 of them at different heights so you can increase the angle.

The legs will be hit into the sand with a sledge hammer and a bit of wood on top.

I was also thinking of cutting a hole with a hole saw on the underneath side of the pipe for the legs to fit into, with a securing pin of some sort to stop it popping out.

See my quality attached diagram.

Does anyone have a better idea? or some other designs.
Or if anyone has tried this?
