Well it had to happen, the first systems failure of the trip. The autopilot developed a mysterious error message so a few hours were spent trying to track down the problem, most probably a short circuit but with all the wiring being fed through small spaces it has been hard to find so that issue has been shelved until Thursday when we spend some time in port. The other issue was a dreaded blocked head (toilet). The culprit was found to be a shell and baby wipe. A joyous experience as I am sure you will all appreciate.
