the designs are pretty simple if you just want a flat rail but building it is a completely different story because there are so many different materials you can build it out of. example: sliding surface can be made from pvc sheeting, pvc pipe, metal rail or plastic deckboard. supports can be either foam billets, barrels or sitting in the shallows.
