I have a couple of Roberts/Attwood generic Rod Holders that I use on my 14ft Aluminum boat that I also wanted to use on my Sit In Kayak by installing the flush mount bases just forward of the cockpit on either side. The problem is I don't think they allow enough clearance for the rod handle and arn't high enough to keep my reels from getting wet. I see they make extensions for other rod holders, but what about these??? Anybody use PVC or something to get your reels outta the water??
