Rudder post snapped on his way to the Azores. He did the spinnaker pole thing and got back to Bermuda. At about the same time a 60 or 70 footer was abandoned by it's delivery crew when their rudder broke. He was towed into St. Georges. Got a new rudder from Hunter, put it in without hauling and was on his way again.
We were crossing Canaries to Caribbean at the same time as the Northern Light rudder failure. The owners tried for days to jury rig something while other boats stood buy. In the end they abandoned it. It washed up on Barbados a few weeks or months later.
Canaries to Caribbean can be a very rough passage. I have done that passage three or four times and that one was the worst I had ever done. Sleep was nearly impossible. It was like being is a washing machine. Large wave trains coming from two different directions. Jury rigging steering in those conditions would be mighty tough.
Max, you have a couple of things in your favor. A skeg hung rudder and an Aquamet 22 solid rudder post. A suggest that you carry a spare set of steering chain and cables and maybe replace the ones in place if they are original. I have had broken chains a couple of times. You can buy sets made up by Edson or you can make them yourself for about 1/3rd the cost. McMaster-Carr carries the SS chain and master links. You can re-use the bronze chain ends. The cable is standard 7X7 wire and nicopress ends. You will also need some large heat shrink tube to cover the chain end to wire connections.
