I have about a 8 ft piece of 1 1/4" round pvc glued into a 1 1/2" t-cupling. The 1 1/2" will then slide over the seat pole. I will set the depth and tape the light cord to the end of the pvc pole. What i like about it is you can swing it to either side of the boat or just raise it alittle and swing it onto the deck and move to a diff spot without taking anything apart.
