Likely late to the party for this one, but I just added paddle making to my list and I had bought a couple of books, the one by Warren and Gidmark has a section on repairing broken shafts.
I remembered reading it, because at the time I thought it was just plain clever how they suggested the repair.
I will try and explain without pictures ( I don't have any, except the hurried sketch). Basically, they cut an arc that intersects the shaft centre ( at the break point) and extends 3-4" beyond the break. Once 1 side is done, repeat the process on the other side.
You can use different wood(s) to jazz up the repair to make it look like a feature, use similar wood to make it blend. Depending on the paddle use and type, you can extend the repair arc as required for strength or even artistic impact.
Overall I thought it was a really good repair technique.
