Picked up my first drift boat. It came with a set of what I believe to be Cataract Oars. There is a label on one oar that is really faded and I believe it says catarack. They are Yellow Fiberglass shafts with wood handles and wood blades. Handles and blades are held in with a single phillips screw. The shafts seem to be fine, the handles and blades are junk. I removed screw and tried to remove blades but no luck, I believe the wood is rotted and swelled up. My question is, I just see blades now that have the push button to attach to shafts. Are these Shafts still servicable of can you not get blades and handles like this anymore?
