I have read more than once here how people store the spare oar in their driftboats. It takes up space and is in the way. I am setting up a boat I am just finishing and came up with this solution. In archery take down two piece long bows and recurves are quite the rage. They are much easier to fly with and travel in general. So I just applied this concept to an oar. It will work with a composite or a wood oar. First saw the Oar in two. Then take two pipe ends one with male threads and the other with female threads. Each one about 4" long and the same ID as the OD of your oar or close. Epoxy one pipe end on each end of your oar. Your Oar now will screw together when you need to use it but you can store it in two halves. Make sure you clean and sand the inside of the pipe and the outside of the oar. and seal the ends of the oar with epoxy as well. If using a composite shaft you will also need to fill the composite shaft with wood or another material the length of the pipe collar that you use. I made my own oars so I tested the breaking strength of the new set up and the wood failed on the oar shaft away from the collar so it is plenty strong. Takes about 30 minutes.
