Seadog Nylon Oarlocks part#s SD-580157 or Sd-580158 - a pair $3.60 will work, shaft is too long so you will have to hack saw them to size (~1 1/2"), of couse you will lose the lock part which didn't work, put a small hole on each side of oarlock and run a wire between them, this will prevent them from going overboard, as they will stay on the oar. I spent some hours finding these, got mine from e-bay,(Canoe oarlocks??) but Defender Industries also spent much time helping me and also found them at Duckworks Boatbuilder's Supply (www.duckworksbbs.com) Hope this helps all, this Seawothy inflatable may be old but is still in good condition
