Alchemy is now in the boatyard, on closer inspection of the rudder, it is clear to us how lucky we were that Alchemy returned us safely to port. This was a close call.
The next steps are to remove and replace the rudder, we don’t think that repair is possible. A vehicle has been rented and transportation plans are being made for all of us to depart and return to our respective homes.
Thanks for the short but educational experience, I feel that I am a better sailor now having taken this journey.
