I wanted a paddle retainer to store my spare paddle on the front deck of my kayak. I decided this was a good idea because of two reasons. First, it will help to hold the paddles in place. Second it is a visual reminder to take the spare paddle along.
I found an pvc return pipe with 180 degree bend at HomeDepot (I think it is 2 inch) and then found an adapter the reduces the size of the hole. I drilled a hole in either side and attached it to the deck safety lines. I positioned it so that the front bungies would also act as a an additional support so it doesn't flop around in the breeze on top of the vehicle. The following images are self explanatory:

Update: Here is an addendum to my kayak retainers to give those more support by adding extension pipes. I boiled water in a pot and and put the 180 bend pipe in the water for about 5 minutes (just tried to cover the bend area with water rather than the fittings). I am not sure if the fitting bent or the bend area bent more but I was able to get a bit of an angle. I used liquid steel epoxy to glue it together - I think this will work.
Here is the result.
